Rachel Baker is the main character in Washington Wax Museum, but this isn't the first we've seen of her. The previous American Chiller, South Carolina Sea Creatures, introduces Rachel as a secondary protagonist partway through the story, along with her brother Derek. Derek isn't in Washington Wax Museum, but Rachel will have plenty of trouble to handle by herself when her class at school takes a field trip to a new wax museum in their home city of Seattle, Washington. Judging by promotional photos, she knows the realistic wax figures are almost impossible to distinguish from live humans. The horror exhibit, at least, promises to be entertaining, but Rachel and her friend David Rydell are about to get more adventure than they bargained for.
Being scared of wax figures seems silly, but Rachel gets a chill as she first enters the big, echoey museum. Mr. Lakley, the museum director, greets the kids in a startling yet memorable manner, then leads them on a tour of the building, explaining its long history and why the city arts council decided to turn it into a museum. Rachel and David don't mean to get separated from the group—their teacher, Mrs. Tupper, has promised to take the class out for pizza if their behavior meets expectations—but Rachel forgets about this incentive once she and David discover that a few wax figures of U.S. presidents are suddenly missing. Before they have a chance to alert Mr. Lakley, Rachel, David, and Amber Caplin—a girl Rachel does not get along with—end up lost in the basement, where they see dozens of wax figures that aren't up for display. What are so many of them doing down here, out of the public eye? The museum sure has some peculiar practices.
The field trip was meant to be fun, but Rachel, David, and Amber's lives are imperiled when they stumble onto the truth: thieves are stealing the wax figures to sell to international collectors. The whispers Rachel heard earlier from seemingly unoccupied parts of the museum weren't ghosts as she feared, but burglars in action. Would these men harm Rachel, David, and Amber to stop them from telling anyone what's going on? Can three kids bring the bad guys to justice, or will the field trip end in disaster?
There isn't much that establishes Washington Wax Museum as a story set in the Evergreen State. A few "fascinating facts" about Seattle are mentioned, but most of the action takes place indoors, and a wax museum could exist in any state. Aside from that minor issue, the story is plausible and has a scattering of exciting moments as Rachel, David, and Amber do their best against the thieves. Like a few other American Chillers—including Poisonous Pythons Paralyze Pennsylvania and Creepy Condors of California—Washington Wax Museum contains no supernatural elements. It's the best entry in the series since Virtual Vampires of Vermont, however, and David is an especially likable character whose level-headedness comes in handy when faced with outlaws. I enjoyed this book.
