The Three Investigators

#12 The Mystery of the Laughing Shadow by William Arden, 1969.

The mystery begins when Bob and Pete are bicycling by the old Sandow estate and they hear a call for help. Although it’s dark they can’t see who yelled for help, they can tell that the person threw something small that lands near them. They pick it up and discover that it is a small gold amulet. Then, Bob and Pete have to hide when a dark, shadowy figure comes looking for the amulet. The figure appears humpbacked and has a weird laugh that Bob and Pete have trouble describing.
They tell Jupiter what happened, and he joins them in searching for the person who called for help and figuring out the significance of the amulet. Someone steals the amulet from Jupiter, although Jupiter manages to save a message that was hidden inside the amulet. Then, they consult an expert in Native American languages and antiquities and learn that the amulet may be part of the Chumash treasure hoard, a treasure stolen from the Spanish settlers of the area many years ago by Chumash Indians (Native Americans) who once lived in the area. People have searched for the treasure for many years, but no one has found it. However, the message that was hidden inside the amulet is written in a language that belongs to the Yaquali Indians of Mexico (this is a fictional group, not the Yaqui), a remote tribe mostly living in isolation but known for their climbing skills. The expert is puzzled because he can’t figure out what the connection can be between the Chumash and the Yaqualis. The two group don’t live in the same area, their languages aren’t related, and the Yaqualis had nothing to do with the lost Chumash treasure hoard.

Jupiter says that their next move should be to investigate the Sandow estate. At first, they plan to make an excuse that they’re researching the Sandow estate for a school project, but to their surprise, Ted Sandow, grandnephew of Sarah Sandow, who owns the Sandow estate, shows up at Jupiter’s uncle salvage yard. Ted is just a few years older than the Three Investigators, and he explains that he came from England to visit his Great-Aunt Sarah after his father died. He says that his aunt wants to clean out a bunch of old things that have been in storage on the estate and that someone recommended the salvage yard to him. He invites the boys to the estate so he can show them some antiques that Jupiter’s uncle might want to buy. It seems like quite a coincidence that Ted Sandow would just come looking for them and give them an invitation to the Sandow estate just when they were planning to investigate the place, but the boys can’t pass up the invitation.

At the Sandow estate, the boys are amazed at the antiques that Sarah Sandow is offering to sell, and they’re sure that Jupiter’s uncle will be interested. They spend some time chatting with Ted, Great-Aunt Sarah, and Mr. Harris, a friend of the Sandows who has started a Vegetarian League with the help of Sarah Sandow. Sarah tells the boys that the reason she wants to clean out some of the clutter around the estate is that they recently had a burglary. They all explain to the boys that a small gold statue (the amulet) was stolen from the estate by an unknown boy. It was one of a pair that used to belong to Sarah’s brother, who was Ted’s grandfather. The boys explain that they are investigators and that they would be happy to help them recover the little statue, without telling them that they had it in their possession at one point or about the message they found with it. The Sandows hire boys to find it, promising them a reward if they’re successful, but some things about their offer don’t ring true.

For one thing, Ted Sandow asks the boys about the meaning of the question marks on their business card before he even looks at the card, indicating that he already knew about their investigation business and that he sought them out for that purpose rather than just to sell things to the salvage yard. It’s also strange that he stresses that they will reward the boys for the return of the amulet with “no questions asked” about how they found it. What are the Sandows hiding, and what is the meaning of the message that was with the amulet? Do they know the location of the Chumash hoard, or do they have it themselves? Who was the mysterious shadow with the weird laugh? Lives may hang in the balance as the boys struggle to learn the identity of the laughing shadow.

My Reaction
I like books that reference history, but this book bothers me a little because of the introduction of the Yaquali. The Chumash are real, but the Yaquali are a fictional group, and it just feels strange to have the book start with a real group of Native Americans and then incorporate a fictional group. It also makes the story feel a little contrived that the villain needs the Yaquali for their excellent climbing skills to reach the treasure when it doesn’t seem like the Yaquali had anything to do with placing the treasure where it’s hidden.
The explanation behind the laughing shadow also feels a little contrived. There’s a logical explanation but at the same time, it depends on the villain having a pet that makes a sound that sounds like a laugh, and this pet’s origins point to the villain’s origins.
The part of the story that I thought was most interesting was that, while the Three Investigators are suspicious of the Sandows, it’s implied that the suspicious is mutual. The Sandows offer the Three Investigators the job of finding the amulet with “no questions asked” about how they found it, and there is an implication that they suspect that the boys stole it. The implication that the “no questions asked” is actually an invitation to the boys to return what they took with a promised reward and no repercussions. However, at the same time as the boys accept the job from the Sandows, they have their own suspicions about what the Sandows are doing and what the meaning of the message in the amulet is. They see the investigation job as a way to learn more about what’s going on. The interesting part is that, while each of them has some reason to suspect each other, the real culprit in this situation isn’t either of them.
Spoilers
Although the boys suspect Ted at first, the real villain is Harris. Years ago, Sarah Sandow’s brother, Ted’s grandfather, learned that the Chumash hoard was located on their property, but for reasons that no one seems to know, he killed the only person who could tell him where it was and had to leave the country. Ted was born in England, and he has been visiting his Great-Aunt Sarah. He met Mr. Harris on the way here, and Harris introduced himself to Sarah on the pretext of getting a donation to help set up a society for vegetarians in the area. He had already figured out where the hoard was located on her property, and he had convinced some young Yaqualis from Mexico to come to the United States to help him get it.

The treasure is hidden in a cave which can only be reached by experienced climbers, and the Yaqualis are known for their climbing skills. One of the Yaqualis realized that what Harris wanted them to do was illegal and that he was planning to do away with them when it was all over. He managed to get word to his family, and he put the message in the amulet in the hopes that someone would find it later and help him and the others.
Jupiter figures out that Harris is the villain when he realizes that the mysterious laugh isn’t human; it was caused by a kookaburra, a pet of Harris’s from Australia. His shadow only looked humpbacked because the bird was sitting on him at the time. Jupiter gets the police to check with the Australian authorities, and they learn about Harris’s criminal past. By then Harris has taken Bob and Pete hostage, and they must stage a daring rescue to save them. For a while, Bob and the young Yaqualis are trapped in the cave with the treasure, but a couple of other Yaqualis who have been searching for them help to rescue them. At the end of the book, the ownership of the treasure still has to be determined, but many museums are hoping to acquire pieces for their collections.
