TACK Secret Service by Marvin Miller and Nancy K. Robinson, 1982.

This book is part of the TACK mystery series, which is very much like the Encyclopedia Brown series, although it’s not as well known and doesn’t have as many books. In fact, my copy references Encyclopedia Brown on the back: “Move over Encyclopedia Brown … make way for the TACK Team!”

The books in the series are collections of short mysteries that readers are invited to solve along with the characters before looking at the answers. TACK is an acronym for the names of the main characters. They’re kind of a mystery-solving club of neighborhood kids, although they say that they don’t really have a clubhouse or regular meetings. They just help out members of their community by solving problems whenever they can.

T = Toria – Her full name is Victoria Gardner, but she doesn’t like being called Vicky. She is the one who narrates the stories. She wants to be a newspaper reporter when she grows up, and she considers the journals she keeps of the group’s cases to be good writing practice.

A = Abby – Her full name is Abby Pinkwater. Abby and Toria were best friends before she moved away. Now, Abby is considered their “Agent-on-Remote” because the others still consider her part of the group, and she still becomes involved with their mysteries, even though she no longer lives close.

C = Chuck – The stories in this book don’t explain very much about Chuck and his background compared to the other characters, although he has a dog named Duchess who is the subject of one of the stories.

K = Will – His full name is Will Roberts, and he’s the leader of the group, although he leads in a very informal way. Will’s initial is the odd one out. They use ‘K’ in place of his initial both because it makes their acronym easier to pronounce and because ‘K’ stands for “SWITCH” in telegraph language, and they think that’s an appropriate code name for him “because of the way his mind can switch all over the place.”

Overall, I like the characters in the stories, and I think they’re well-written. They would be of interest to people who like Encyclopedia Brown and similar types of Solve-It-Yourself style mysteries.

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

Stories in the Book:

TACK Secret Service: Operation Goldfish

The kids are getting ready for the science fair at school. They are not looking forward to the arrival of kids from a rival school because they don’t play fair, and a boy called Red Jamieson sometimes deliberately wrecks other kids’ projects. Will is helping a boy named Hugo to protect his project because someone stole the plans for the project the day before. The kids suspect Red and his friend, Lester. As the kids try to maintain surveillance on the exhibits, someone steals one of their walkie talkies and threatens to ruin it if they don’t turn over Hugo’s invention for remotely feeding goldfish.

The Locked House Mystery

Will and his brother Cyrus are staying with Toria’s family for a few days while their parents are on a skiing trip. The only problem is that Toria’s family has a cat, and Cyrus is allergic to cats. At first, they think it will be okay because Cyrus has his allergy pills, but it turns out that he forgot them at home, and he also forgot the house key. How can they get his allergy medicine from a locked house when they can’t reach the spare key?

The Pirates of Sandy Harbor

Toria is writing a report about the founder of their town, Simon Hawk, but she needs more information. She goes to the local historical society, but there, she discovers that an old note has been found that indicates that Simon Hawk may not have been the hero that everyone believes he is. Rather than chasing off the pirates that plagued the area, he may have been in league with them! Toria can’t finish her report until she knows the truth, but fortunately, Will spots something about the message that clarifies everything.

The Dance of the Trees

Toria’s sister, Holly, is in a dance recital with her ballet class where the best dancer in class gets to be a fairy, and the other girls get to be living trees. (Holly isn’t thrilled about that until she see the tree costumes, which are pretty cool.) Unfortunately, the girl playing the part of the fairy gets sick, and there isn’t enough time for someone else to learn her part. What can they do?

A Slipper for Ripper

Chuck worries that his mother will give away his dog, Duchess, if she doesn’t stop chewing things. They’ve tried giving her all kinds of chew toys, but she doesn’t like any of them. She just wants to chew things that belong to people. Will’s younger brother, Cyrus, thinks he’s found a solution, figuring out how to make what he calls “dognip.” However, when they arrive at Chuck’s house, Duchess has a slipper belonging to Chuck’s mother. Cyrus hurriedly gets the slipper away from Duchess and throws it into the next yard, but that’s where the violent dog Ripper lives. At first, the kids’ attempts to distract the dog and get the slipper only make the situation worse, but Will figures out how they can retrieve everything from Ripper’s yard safely.

The Case of the Haunted Dollhouse

Toria’s best friend, Abby, who moved away before the beginning of the book, calls Toria to tell her that her family is coming back to town to visit her grandmother, and she can see Toria when they come. However, this isn’t just an ordinary visit. Abby’s family is concerned because her grandmother is acting strangely, and her parents are worried that she might be getting senile. She’s talking about selling the fantastic dollhouse that she’s had since she was little, which is now a family heirloom. She’s become afraid of it because she thinks it might be haunted.

The Haunted Dollhouse – Part II

The kids figure out what’s created the haunting phenomena in the doll house, but when they go to tell Abby’s grandmother about it, they learn that she’s moved out of the old family home where she also runs her antique shop because other strange things have been happening. The temperature in the house inexplicably drops, and she’s been hearing music that seems to come from the dollhouse with no apparent cause. The adults are still concerned about her mental state, but the kids realize that there’s someone who’s behind all the strange things that have been happening. Who is playing ghost?
