Dig for a Treasure

This is the second book in The Invisible Island series. It begins with the arrival of the Lennox family and their two children, Hugh and Barbie. The Lennox family has been staying with various relatives since the father got out of the army, but now, they’ve found a house to rent in the small town of Anchorage, Connecticut. The children are looking forward to having a yard to play in, and the mother wants to have a garden.

Unfortunately, when they arrive they are shocked to see that the house they were going to rent has been destroyed by fire. Their landlord, Mr. Prentice, is also on the scene, and he regretfully tells them that the fire just happened, although they don’t know the cause, and that there are no other houses in the area to rent. At first, they think that they will have to go back to staying with relatives, but Mrs. Lennox says firmly that they won’t. The family has had enough of staying with relatives, and they desperately need a place of their own. It’s summer, so her idea is that they can camp out on the property of the burned house for a few months while they look around for another place to rent. The children are excited about the idea of a camp-out. Mr. Prentice says that he wouldn’t have any problem with the family camping on the land, and he returns their rent deposit to them, saying that they can stay at his house that night and get some camping equipment the next day.

While Hugh and Barbie are exploring the area and looking for their cat, who ran off, they meet the children from the first book in the series. Hugh is about the age of David Guthrie, and Barbie is about the same age as Winkie Guthrie, the youngest of the children who play on the island they call “The Invisible Island.” Since the previous book in the series, they have finished their stone hut, and it has a grass and sod roof and four built-in beds for the four Guthrie children. Mr. Guthrie is an architect, and he helped the children build the house.

Hugh and Barbie admire the hut, and they say that they wish they had a stone house like that because it couldn’t catch fire. They explain to the other children what happened to the house that their family was going to rent, and they ask the children if they would consider renting the stone hut to their family until they can find another place to live. Mr. Lennox isn’t really happy about the idea of camping in tents because he lived out of tents when he was in the army.

At first, the Guthrie children and the Leigh children aren’t sure that they want to rent out their stone hut. They spend a lot of time there, and they’ve been trying to save up money to add improvements. The hut really belongs to the Guthries, who built it, but they want to add an extra room for the Leighs. However, after thinking it over, they realize that they can earn more money as rent from the Lennox family than they can by just doing chores, and while the Lennox family stays in the hut, they can camp out on other parts of their little island, like the woods that they call “Sherwood Forest.”

Since the little hut is just a one-room hut with no bathroom or other amenities, the children aren’t sure at first whether the Lennox adults would want to stay there or not. However, staying in a stone hut does sound better than in a tent, where they would also have no bathroom or amenities. Mr. Lennox is also intrigued by the pond, where he can go fishing. The children and the Lennox family talk things over with Mr. Prentice and the Guthrie children’s parents, and they all agree to renting the stone hut to the Lennox family.

The Lennox family still isn’t sure whether or not they’ll find another house for sale or rent in the area. They want to stay in the area because Mr. Lennox has a job nearby and Mrs. Lennox knows that some of her ancestors used to live in the area, although she doesn’t know much about them. However, Anchorage is a small town, and most of the houses already have people living in them. There is only one empty house in the area, but the owner has always refused to rent it or sell it. Mr. Prentice explains that the owner believes that there is a treasure in the house or nearby, a necklace that once belonged to a queen, and she’s been looking for it for years. Mr. Prentice doesn’t think that there really is a necklace or, if there once was, it’s probably long gone, but the owner insists that it exists and is still there, somewhere.

The children are fascinated, and they ask Mr. Prentice to tell them the story of the queen’s necklace. He says that during the time of Queen Elizabeth (Tudor), the ancestors of the Winthrop family who owned the house did something for Queen Elizabeth that caused her to reward them with a golden necklace that was passed down through the family for generations. When the Winthrops came to the colonies in America around 1650, they brought that necklace with them. However, when they came to this area and settled there, they had problems with the local Indians (Native Americans).

Mr. Prentice says that he can’t blame the American Indians for resenting strangers coming and taking over their lands and hunting grounds or for them trying to stand up for their rights, but the situation escalated with increasing violence. David Guthrie protests that American Indians scalped people and that, if he’d been there at the time, he’d “show them.” Mr. Prentice explains that was exactly the problem – everybody who was there at the time thought he’d “show them”, and that’s why the violence escalated. As for the scalping, Mr. Prentice says that white people committed their share of atrocities, too, and when David is older and learns more about it, he might not feel so proud of his side in this battle. (I thought that was an amazingly honest and self-aware interlude about European colonization and its effects on Native Americans for a book written in the late 1940s, when cowboy and western shows were becoming popular, and American Indians were mainly portrayed as violent enemies to be defeated. I was a little concerned at first when “Indians” entered the story, but I was relieved that the author took this attitude.)

Continuing with the local legend, Mr. Prentice explains that the colonists received warning one day that the local tribe was going to attack. In preparation for the attack, some families hid valuable items that they didn’t want stolen or destroyed in the coming battle. Some people buried valuables, and others hid their valuables in wells or caves. Presumably, the Winthrops hid their necklace, called the Queen’s Chain, during this time, but nobody really knows what happened to it. The colonists fled the area, and the American Indians burned the entire village to the ground. Every man-made structure was destroyed during this attack. Although people later returned to the area and rebuilt the town, it’s unknown what valuables they retrieved or when or if they ever retrieved them from their hiding places. Because all the buildings and some of the trees were burned, many landmarks were destroyed, so some people might not have found their hidden valuables again, even if they managed to return to look for them.

Mr. Prentice is related to the Winthrop family, and so is his cousin, Lizzie, who currently owns the rebuilt house known as the Winthrop house. Lizzie is firmly convinced that the Queen’s Chain is still there, somewhere. She thinks it was never hidden during the attack that destroyed the first house and was passed down through the family but hidden by a later generation, which is why she won’t sell or rent the house. Mr. Prentice, on the other hand, thinks that the necklace is lost forever. He thinks that either the necklace was hidden with other valuables that were never retrieved after the attack or that the family found the necklace and sold it to get money to rebuild the farm that was destroyed. Mrs. Prentice, on the other hand, sides with Lizzie, saying that nobody in the Winthrop family would have sold the necklace because it was part of a family trust.

The children are fascinated by the story, and they immediately begin thinking about searching for the necklace themselves. They talk to Miss Lizzie about the story Mr. Prentice told them and use some of the descriptions that she gives them of the old Winthrop property and the plants that once grew in their herb garden to see if they can pinpoint the exact location of the original house and the hiding place that the Winthrops might have used for their valuables. Even though everything manmade was destroyed in the attack, some plants have a way of coming back, and the remains of the old herb garden might still be there, even almost 300 years later.

The treasure hunt takes on greater importance when the Guthrie children learn that their family might not be able to buy the island from Mr. Prentice. Mr. Prentice is also the Guthrie family’s landlord, and the family has been saving up to buy their house from him. They had also hoped to be able to buy the island where the children have been spending so much time, but Mr. Prentice is reluctant to sell it. Lumber is valuable, and he’s thinking of cutting down the pine trees on the island to sell the wood. The children are horrified at the thought that their beloved “Sherwood Forest” might be cut down! Perhaps, if they can find the missing treasure, they can persuade Mr. Prentice to sell the land to them and Miss Lizzie to rent her house to the Lennox family.

The book is available to borrow and read online through Internet Archive (in audio form!).

There isn’t as much imaginary play as “castaways” in this book as their was in the first book in the series, but the theme still shows up in some ways. The kids still go camping on the island. They use tents when the Lennox family is living in their hut. The children’s search for treasure also offers plenty of outdoor adventure, and I really enjoyed the element of mystery in the story.

The children approach the treasure hunt from the assumption that the necklace is still hidden wherever the Winthrops hid their valuables. They do find that spot and recover some relics of the 17th century, but the necklace is not among them. Readers probably won’t guess exactly where the necklace has really been hidden, but there are a few clues to notice along the way. Mrs. Lennox says at the beginning that her ancestors were from this town, even though she doesn’t know much about them. I had guessed that they might have a connection to the Winthrops, especially when Miss Lizzie explains that the name of the girl who hid the family’s valuables before the attack was Elizabeth, and there are other Elizabeths in the family. Besides Miss Lizzie, Mrs. Lennox is called “Betty” when her husband addresses her by her first name, and Betty is another nickname for Elizabeth. When Barbie recognizes something that Miss Lizzie has as being like something her family owns, Miss Lizzie realizes that the Lennox family is related to her. By comparing what each of them has and what Miss Lizzie knows about their family, they figure out what really happened to the necklace. It not only solves the mystery of the necklace, but once Miss Lizzie realizes that the members of the Lennox family are relatives, she’s happy to have them living in the old Winthrop house.

The problem of what will happen to the children’s island and the trees on it is solved when the children win a bet with Mr. Prentice. In the first book, the children called their island “The Invisible Island” because it isn’t obvious at first that it really is an island, surrounded by water on all sides. So far, the children have kept the knowledge to themselves and their parents. When the children accidentally refer to the island in Mr. Prentice’s presence and realize that Mr. Prentice isn’t aware that it’s really an island, they start to explain. Mr. Prentice can’t believe that there’s actually an island on his land, and he says that he will give up ownership if they can prove that it’s really an island. The children easily demonstrate that it’s truly an island, showing him all of the waterways and bodies of water around it, and Mr. Prentice says that they’ve won. The Guthries end up with control of the island and the trees on it.

The Mystery of the Goldfish Pond

Three Cousins Detective Club

Timothy’s father wants him to sing at his boss’s retirement dinner. The boss’s wife heard Timothy sing once with his choir, and she wants him to sing a special song for her husband at the start of the dinner. His cousins are invited to come along so he won’t be the only kid there. Timothy doesn’t really want to do the singing, but his parents convince him to do it anyway because the boss’s wife is so fond of him and his singing.

Timothy’s father hopes that the dinner will go well because the boss has been worried about the possibilities of competitors getting their hands on information about their new product. Earlier, the boss temporarily misplaced an important memo about it, and he was worried that someone else got their hands on it.

Timothy’s song goes well, and after the dinner, the kids are allowed to walk outside in the garden while the adults listen to a series of speeches. The gardens outside the banquet hall are beautiful, and the kids start to enjoy themselves. Then, they accidentally overhear a couple of adults talking. They can’t quite catch everything they say, but something strange is going on, and something secret is hidden somewhere in the garden.

The theme of this story is Proverbs 11:13, “No one who gossips can be trusted with a secret, but you can put confidence in someone who is trustworthy.”

The book is available to borrow and read for free online through Internet Archive.

The crime that the adults were plotting involves the theft of information. The kids have to figure out the parts of the conversation they couldn’t hear clearly to figure out where the information is hidden. I thought that the clue the children try to figure out was fairly easy. Part of the conversation the kids try to figure out sounds like “-ake -urtle”, and there aren’t many words that sound like “-urtle.”

The boss’s wife seemed eager for the children to go outside, into the garden, and tell her about it later. The kids wondered why she seemed so eager for them to go outside and what she was hoping that they would tell her afterward. It sets the stage for the kids to expect that something unusual or mysterious might happen, which proves to be the case when they overhear the important conversation. The boss’s wife says later that she suspected something might happen because she knew her husband was worried about people stealing company information, and she realized that this dinner would be a convenient place to hand it off to someone.

We never learn exactly what kind of information or new company products the adults were concerned about. We also don’t know exactly who was trying to steal the information or what happens to that person later. The part that the children care about is that they were able to stop the hand-off of the information.

The Mystery of the Eagle Feather

Three Cousins Detective Club

Timothy is excited because he has a chance to meet his pen pal, Anthony Two Trees, for the first time. Anthony is a Native American, and he will be dancing at a powwow. Timothy’s cousins get to come along on the trip, too.

Soon after they arrive, though, they learn that someone has been taking pieces of the dancers’ costumes, like fans or headdresses made of eagle feathers. Who could be taking the costume pieces and why?

The costume pieces and the eagle feathers they contain are very expensive, and the kids realize that the thief might be thinking of selling them. It is illegal to deal in eagle feathers because eagles are an endangered species. Even the Native American dancers have to write to the government in order to get eagle feathers for their costumes from eagles that died in zoos. Therefore, the costumes are expensive and require a lot of effort to put together, and losing them is a real blow. The rarity and cost of the feathers might prove to be a temptation to a thief.

The theme of the story is self-control.

I wasn’t sure if I was going to like this story. I understand the fascination kids have with Native Americans and their costumes and dances. I felt like that when I was a kid, too, but there’s also an element of cringe to it. The cringiness comes from kids (and even adults) who get wrapped up in the fascination of the appearance of other people’s traditions and treat them more like playing dress-up than traditions with deeper, underlying meaning and significance or depicting Native Americans as being stereotypes from old movies and books rather than real, living people.

Fortunately, I was pleased at how this story shows that Timothy’s friend, Anthony, is a regular boy who shares his interest in baseball. They emphasize that Native Americans don’t live in tepees any more, and they don’t treat the Native American characters like stereotypes. I enjoyed some of the facts the story provided about Native American dances and costumes, like the regulations regarding the use of eagle feathers.

The Mystery of the Silly Goose

Three Cousins Detective Club

As soon as they arrive home from their trip to the powwow in the previous book, the cousins are approached by Timothy’s neighbor, the snobby 13-year-old Lyddie, with another mystery. While they were out of town, someone went around the neighborhood, stealing lawn ornaments. Lyddie is concerned because her grandmother has come to live with her and her parents, and her lawn geese were stolen. One of the geese was the mother goose with a silly-looking bonnet on her head, and the others were her goslings. Lyddie’s grandmother is rather attached to the geese because they were a present from someone.

The three cousins don’t really like Lyddie because she and her friends are usually unfriendly and too concerned with being “cool” all the time. However, they feel sorry for her grandmother and agree to take the case. To their surprise, most of the lawn ornaments are actually pretty easy to find. They were hidden in some obvious places around the neighborhood. The only ones that are difficult to find are the geese. Who hid the lawn ornaments and why?

The theme of this story is Proverbs 24:3-4, “It takes wisdom to have a good family. It takes understanding to make it strong. It takes knowledge to fill a home with rare and beautiful treasures.”

The book is available to borrow and read for free online through Internet Archive (multiple copies).

Part of the mystery has to do with image, but it also has to do with sentimental attachment. Lyddie is very obsessed with image because she and her friends try so hard to maintain their cool image. Although she calls in the cousins to find the missing lawn ornaments, she only does it because her grandmother takes the loss of the mother goose so hard. Lyddie doesn’t see why the goose is so important, although she knows that her grandmother is attached to it because it was a present from someone.

The situation changes when Lyddie’s grandmother reveals the full story behind the lawn geese and her own understanding of the situation. Lyddie cares for her grandmother, and she comes to see the geese in a new light once she understands why they matter to her grandmother. It’s not the value of the geese, and it’s not about how the geese look. It’s all about the person her grandmother associates with them. Fortunately, Lyddie’s grandmother is a very understanding woman, and when the lawn ornament thief explains the issue, they work things out to everyone’s satisfaction.

The Mystery of the Haunted Lighthouse

Three Cousins Detective Club

Sarah-Jane’s parents have been planning a trip, and her cousins, Titus and Timothy are coming, too. At the request of an old family friend, Ned, they are going to visit him and take a look at an old lighthouse that he is thinking of buying. He wants to turn the lighthouse into a bed and breakfast.

However, strange things have started happening at the lighthouse. Someone has vandalized the outside, and Sarah-Jane sees a frightening face up in the tower. Could the old lighthouse be haunted?

The theme of the story is faithfulness.

The book is available to borrow and read for free online through Internet Archive.

Since this is a Christian-themed mystery, readers can guess that there won’t be any real ghosts. This is more of a light, pseudo-ghost story, like Scooby-Doo mysteries, with another explanation for what’s happening.

There’s more than one kind of haunting. People can be haunted by memories, and living humans are also attached to the places associated with their happy memories. There is someone who has an attachment to the lighthouse and is unhappy that it’s being sold. This person needs to reconcile their feelings to the situation.

Some Christians don’t like the concept of ghost stories at all. In the book, Sarah-Jane likes hearing ghost stories, although she admits that she doesn’t like remembering them later, when she’s alone at night. She enjoys a little spooky excitement, as long as she knows it’s just a story, and she’s hearing it in a safe setting.

The Mystery of the Runaway Scarecrow

Three Cousins Detective Club

#26 The Mystery of the Runaway Scarecrow by Elspeth Campbell Murphy, 1999.

Sarah-Jane astonishes her cousins when she tells them that Buster, the scarecrow her mother made, which has been sitting outside of a local restaurant, has gone “on vacation. Scarecrows don’t just get up and go on vacation, and when they say that, Sarah-Jane says that Buster left a note saying that he had gone on vacation. The boys don’t believe scarecrows can write notes any more than they can go on vacation. Sarah-Jane admits that scarecrows don’t write notes, but someone else wrote a note on Buster’s behalf and left it behind when Buster disappeared. The note says that Buster is going on vacation and will be back when someone figures out where he’s gone. That’s weird enough, but Sarah-Jane says that Mr. Wesley, who owns the restaurant where Buster was, has been receiving pictures of Buster on his trip in the mail since he disappeared.

It seems like someone is playing a bizarre prank or maybe setting up some kind of treasure hunt involving the scarecrow. The town mayor says that Buster’s “vacation” has created more publicity for the town’s upcoming Fall Festival, so it could even be a publicity stunt. However, it’s been a few days since the last pictures of Buster arrived, and Mr. Wesley is inviting Sarah-Jane and her cousins to investigate Buster’s disappearance and find him because he knows that they like to solve mysteries.

The kids study the pictures for clues to Buster’s whereabouts, but the pictures are pretty generic. They show him outside a motel, at a gift shop, and at a gas station, but the locations aren’t very distinctive and could be found in any number of cities. The postmarks on the envelopes that pictures came in are all still in the area, so it seems like Buster didn’t go very far. They need to hurry if they’re going to find Buster in time for the town’s parade because the parade is tomorrow!

Then, Sarah-Jane reveals that something else mysterious has happened in the area recently. Someone stole a rare coin from Mr. Clark. This is also an intriguing mystery, but they don’t have many clues to start. Mr. Clark isn’t exactly sure when the coin disappeared because he doesn’t get out his coin collection very often.

For some strange reason, an older boy in Sarah-Jane’s neighborhood, Billy, seems very concerned about whether Sarah-Jane and her cousins have made any progress in finding Buster. Could Buster’s disappearance also have something to do with the missing coin?

Theme of the Story:

“The land has produced its harvest; God, our God, has blessed us.”

My Reaction and Spoilers

I liked the way the person who took the scarecrow used the pictures to provide clues to their treasure hunt. Readers won’t be able to figure it out right away without explanation from the characters because the book doesn’t show all the pictures, but I liked the concept for how the culprit worked a series of clues into the pictures. There’s also a fun backstory behind the scheme. The prankster doesn’t have a sinister motive. The scarecrow caper is meant as a kind of prank/game/harmless publicity stunt.

I guessed pretty quickly who had taken the scarecrow, based on motive, but I liked the addition of Billy and the coin because it complicated the story and provided a second mystery on top of the first. There is a genuine crime in the story, but it’s not the one that the kids start out investigating.

The story takes place during October, but it’s not on Halloween. The town’s Fall Festival just seems to kick off the fall season in general.

The UFO Mystery

This book is part of the Sherlock Street Detectives series.

Halloween is approaching, and the Sherlock Street Detectives are talking about their costumes. David is going to be a bear, and he made his costume out of an old rug. Pedro is going to be a clown. Walter and Ann, who are twins, refuse to tell anyone what their costumes are because they want it to be a surprise.

Then, David says that he has to go home because it’s dinnertime, and after dinner, he’s going to look for a comet with his telescope. Pedro says that he’s never used a telescope before and asks if he can look, too. David says he can, and Pedro says that he will come back to his house when it’s dark.

When David and Pedro meet to use the telescope, David shows Pedro how to use a star map to find the constellations. While Pedro is looking through the telescope, he thinks that he sees a UFO! At first, David doesn’t believe him. It’s too early to see the comet, so he thinks maybe Pedro saw a meteor. Pedro insists that it was a UFO, and David points out that UFO stands for Unidentified Flying Object. That means that anything that “unidentified” can be a UFO. Pedro can’t identify exactly what it was he saw, but that only means that he didn’t recognize the object. It doesn’t have to be an alien spacecraft, just some normal thing he didn’t recognize, like a meteor, a comet, or even just a firefly.

Since David’s dad works for NASA, Pedro says that they should ask him if it could have been a comet other than the one they were expecting to see. However, David’s dad confirms that there should only have been one comet that night and that the comet should have been in a different part of the sky. The boys talk about getting Walter and Ann to help them investigate, but then, they see some strange creatures in the bushes!

What did Pedro really see through the telescope, and could those weird creatures really be aliens?

The book is available to borrow and read for free online through Internet Archive.

This is fun mystery picture book! Figuring out what/who the aliens are is the easiest part of the mystery, since this is before Halloween and the twins were being mysterious about what their costumes are, although it might seem harder to young children. The answer to what Pedro thought he saw through the telescope is revealed first, although I wasn’t entirely sure what to think of it myself. At first, I thought that the “aliens” might have been throwing around some glowing toy or something, but they would have to have thrown it really high to get it in front of the telescope because the boys were using the telescope on the roof. There’s a perfectly logical explanation behind the phenomenon, and David figures it out by noting where the object was and it was moving. David’s father confirms David’s guess with a call to NASA.

One of the nice things about this simple mystery story is that it introduces some real concepts for stargazers and amateur astronomers. There is a vocabulary list and glossary in the back of the book.

This series also offers good representations for racial diversity. Racial issues don’t enter into the story. The kids are just a bunch of kids who happen to live in the same neighborhood and are friends and like to solve mysteries, but they are a mixed racial group, and that’s nice to see. David is black, Pedro is Hispanic, and the twins are white. The children’s races are not referred to in the text of the story, but they are shown in the pictures.

Spooky Sleepover

A couple of weeks before Halloween, Ernie decides to have a sleepover party for her friends. The kids enjoy scaring each other with ghost stories, and a thunderstorm adds to the spooky atmosphere.

Michael, in particular, keeps insisting that an old witch called Mrs. Maloney used to live in Ernie’s house with a bunch of cats. When spooky things happen during the course of the evening, Michael says that Mrs. Maloney and her cats have returned to haunt Ernie’s house. The kids try to stay up until midnight because ghosts are supposed to appear at midnight, but there’s no telling what they might actually see.

The kids fall asleep, but they wake up around midnight when they hear a crashing sound from the basement. Although they are afraid, they take their flashlights and go down to see what it is. Will they find a ghost?

The book is available to borrow and read for free online through Internet Archive.

This is one of those stories that has a pretty simple explanation, but the adventure seems bigger to the kids because their imaginations run away with them. I remember liking this series when I was a kid, and I think this is one of the books I read back then. I liked the creepy-cozy atmosphere of the story. Even though the kids have been scaring each other with ghost stories, they’re still just at a sleepover in an ordinary, safe house, and there’s nothing there that is harmful. It’s that kind of safe scariness that Halloween represents to young kids. They can enjoy the spookiness, knowing that there’s a logical explanation for everything. Adults and older kids will figure out pretty quickly what’s really going on.

Frankenstein Moved In on the Fourth Floor

Frankenstein Moved In on the Fourth Floor cover

Frankenstein Moved In on the Fourth Floor by Elizabeth Levy, illustrated by Mordicai Gerstein, 1979.

Frankenstein Moved In on the Fourth Floor new neighbor

Sam lives with his brother and mother on the 19th floor of a large apartment building. One day, when he and his mother are going to meet his brother at a friend’s house, they try to take the elevator down to the ground floor, but it doesn’t seem to be working. With no other choice, they take the stairs, and when they reach the fourth floor, they discover the reason why the elevator isn’t working.

A new neighbor, Mr. Frank, is moving into the apartment building, and he’s stopped the elevator at his floor to unload all of his stuff. He has boxes and boxes of wires and other electronic components, and he gets really upset when anybody else touches them. He has refused all offers of help to unload the boxes, he’s kept the elevator tied up, and he’s been rude to his new neighbors about these things.

Frankenstein Moved In on the Fourth Floor reading book

Sam thinks that Mr. Frank is frightening. He looks weird with those strange headphones with an antenna he keeps wearing. When he and his mother go to pick up his brother, Robert, Sam tells him about Mr. Frank and his theory that Mr. Frank is actually a monster. Sam thinks that Mr. Frank looks like Frankenstein. Both of the boys are into movie monsters, but Robert thinks at first that Sam is making it up. The boys have a debate about whether Mr. Frank would actually be Frankenstein the scientist or the monster that Frankenstein created in the book and movie because, although many people call the monster Frankenstein, that was actually the name of the monster’s creator. When the boys consult an abridged version of Frankenstein, Sam becomes convinced that the book’s description of Frankenstein the scientist sounds like Mr. Frank.

The next day, the boys go down to the apartment house’s basement, where tenants have storage rooms. Sam wants to see what Mr. Frank is storing in his storage room, but when the boys start talking about the possibility that he might keep bodies in there, they chicken out. In the meantime, Mr. Frank gets on everyone’s nerves at the apartment house. He’s always bringing in new boxes of stuff and leaving empty ones around. Neighbors hear weird noises coming from his apartment that sound like moans and groans. Mr. Frank claims that the noises are his music. Then, he overloads the electrical circuits in his apartment and causes the entire building to black out. Nobody knows what he’s doing with all that electrical equipment of his. Mr. Frank’s weird electrical experiments make Robert think maybe Sam was right about Mr. Frank being Frankenstein.

Frankenstein Moved In on the Fourth Floor discovering the Dracula doll

The boys decide that it’s important for them to take a look in Mr. Frank’s storage room, but when Robert accidentally leaves his Dracula doll behind, they realize that Mr. Frank will find out that they’ve been snooping. They may have to face the wrath of Frankenstein!

The book is available to borrow and read for free online through Internet Archive (multiple copies). There is a sequel to this book called Dracula is a Pain in the Neck.

My Reaction and Spoilers

Frankenstein Moved In on the Fourth Floor confrontation

This story is a kind of mystery story because the boys are trying to figure out if Mr. Frank is actually Frankenstein and if he’s making monsters with his electrical experiments. However, it really reminds me of the The Adventures of the Bailey School Kids, a series about kids who suspect various people in their town of being different supernatural creators. This book is older than that series, and from the way the story goes, there are more logical explanations for Mr. Frank’s behavior. However, like with The Adventures of the Bailey School Kids, the kids don’t really get firm answers at the end. It looks like Mr. Frank is probably just some weird, temperamental musician who likes to experiment with electronics, but the story leaves it open to interpretation.

The Mystery of the Invisible Dog

The Three Investigators

Shortly after Christmas, a frightened man, Fenton Prentiss, calls the Three Investigators to his apartment to help him. Mr. Prentiss is an elderly art collector, and he says that he is being haunted. Things in his apartment get moved around when he’s not there, and he can tell that someone has been reading the mail in his desk. Sometimes, he even sees a shadowy figure when he is home, although he’s never gotten a good look at it before it disappears. He swears that it can’t be another person because he’s the only one who has a key to his apartment. He is also sure that there are no secret passages in his apartment building and that there’s no way for any living person to enter his apartment without being seen by someone. Mr. Prentiss could just be imagining the haunting, but Jupiter is intrigued, and if the boys don’t have a mystery to work on during the holidays, they know that Jupiter’s aunt will just assign them a bunch of chores.

They tell Mr. Prentiss that they need to talk over the assignment together before they accept his job, but Jupiter’s mind is made up when he also sees a shadowy figure that he initially mistakes for Pete just before they leave the apartment. However, Pete is not in the room where Jupiter saw the shadow. Did Jupiter just see Mr. Prentiss’s mysterious ghost?

When the boys get outside the apartment, they hear a loud bang and running feet and see a man in a ski mask running away. Pete tries to follow, and the police stop him, thinking that he might have something to do with a burglary that has just taken place. Fortunately, Mr. Prentiss speaks up for Pete, saying that the boys only just left his apartment and couldn’t have anything to do with what the police are talking about. The police think that the suspect who ran away could have gone into a nearby church, but he seems to have vanished. Mr. Earl, the janitor and caretaker of the church swears that he was in the church the whole time and no one came in, although the housekeeper at the rectory, Mrs. O’Riley, says that Mr. Earl is practically deaf and wouldn’t have heard anybody.

The place that was burgled turns out to belong to a deceased artist friend of Mr. Prentiss. His friend’s death is part of the reason why Mr. Prentiss is so on edge because it was very upsetting to him. The artist’s brother, Charles, hadn’t finished clearing out his brother’s house when it was robbed. He tells the boys that his brother was a sculptor, and his best piece was based on a legend of a ghostly, demonic hound from Eastern Europe. This is the sculpture that was stolen. It’s a bitter blow to Mr. Prentiss because the artist made this sculpture especially for him.

Jupiter believes Mr. Prentiss that someone has been sneaking into his apartment, so he sets a trap that will cause the intruder’s hands to be stained. Mr. Prentiss leaves for a while with the boys, and when they return, his nosy landlady’s hands are stained, indicating that she has been the intruder. Mr. Prentiss confronts her, and she admits that she had a spare key made for his door. The landlady has a long-term habit of spying on her tenants. Mr. Prentiss confiscates her spare key and thinks that his problem is over, but really, it’s just beginning.

Having seen the shadow in Mr. Prentiss’s apartment himself, Jupiter knows that the mysterious shadowy figure was not the landlady. For Jupiter to have mistaken the shadowy figure for Pete, he knows that the person is male and of similar size to Pete. Jupiter is not surprised when Mr. Prentiss calls them up to say that he’s seen the shadow again. The landlady was undoubtedly snooping, but there must also be a second intruder. At first, Jupiter thinks that he knows who the second intruder must be because there is another person in the apartment building who vaguely resembles Pete and who also seems to know about things that Mr. Prentiss owns when he’s supposedly never been in Mr. Prentiss’s apartment before. However, this person is accounted for when the intruder makes another appearance. Jupiter investigates the nearby church when he sees a light there, and he has a frightening encounter with a figure that Mrs. O’Reilly believes is the ghost of the former pastor.

Mr. Prentiss soon gets a ransom demand from the person who stole the sculpture. Then, strange misfortunes start to befall Mr. Prentiss’s neighbors. Some of these misfortunes look like accidents while others are direct attacks. Someone is apparently attacked by the thief, someone else is poisoned, someone’s apartment catches fire, and someone else’s car is sabotaged, and people are ending up in the hospital. It seems like someone who is close to these people is responsible for sneaking around Mr. Prentiss’s apartment, stealing the valuable sculpture, and harming the neighbors, but who is doing these things and why?

The book is available to borrow and read for free online through Internet Archive (multiple copies).

I enjoyed this mystery because it has many different facets. First, there is a wonderful cast of eccentric characters. All of Mr. Prentiss’s neighbors/suspects are eccentrics. There’s the nosy, sneaking landlady and a guy who takes care of stray cats. Mrs. O’Reilly at the church believes that the church is haunted by the ghost of a former pastor, adding another haunting figure to the mystery. Another resident of the apartment house works nights at the local market and is saving up money so he can go to India and find a guru to help teach him the secrets to life. His father wanted him to be a dentist, but instead, he wants to study meditation so he can see through life’s illusions and be truly awake, achieving the ultimate level of consciousness. It’s ironic because he’s so tired from working nights that he often falls asleep while meditating. The mystery somewhat resembles a classic old dark house mystery in the sense that it takes place in a contained area with a very definite set of suspects who are also either victims or potential victims.

Second, I enjoyed the layers of the mystery. We have a mysterious intruder (or intruders), the theft of a valuable sculpture, a possible haunted church, and a series of mysterious accidents or attacks on residents of the building. Are these things all connected or are some of them unconnected incidents that confuse the issue? Readers have the feeling that there are at least some connections, but it’s not clear for most of the story what the connections are and who’s responsible for what. On the one hand, books with several different mysterious happenings can feel a little cluttered and confusing to readers, but on the other, figuring out which of these incidents are connected to the main issues provide clues to the identity of the real villain.

There is a surprising supernatural element to the story that the Three Investigators discover when they consult a parapsychologist at a university. There was a strong interest in parapsychology during the 1970s and 1980s, which is why the subject of psychic abilities and people who study it appears in children’s books and tv shows around this time period. (Spoiler) It seems that the guy who is studying meditation has some psychic ability, and the things he experiences while meditating aren’t just him falling asleep and dreaming, although it seems like that at first. Because he really wants to get away from his boring life and dead end job when he meditates, he’s actually been using a kind of astral projection without being fully aware that’s what he’s doing. The characters realize this because he knows things that he shouldn’t really have any way of knowing from places where he shouldn’t have been and how he can sometimes appear in certain places when he’s actually somewhere else. Some of the strange things that people see around the apartment building at due to his astral projection, possibly including the ghost in the church, although part of that is left unclear at the end. However, there is a real thief and villain in the story who is unrelated to the psychic phenomena, and incidents that harm people in the building are related to the thief’s attempts to keep people away from the hiding place of the stolen sculpture. I thought both the psychic angle and the solution to the theft were clever, and I kept guessing all the way through the book who was responsible for what.
