At the same time Barbara Park was making a name for herself with juvenile humor novels in the 1980s, so was Lois Lowry. One might not think of her as a humorist, but Ms. Lowry could be almost as funny as Barbara Park. Caroline Tate, age eleven, is an apartment-dwelling girl of 1980s New York City. Her interest in dinosaurs is insatiable; she regularly visits the Museum of Natural History to explore the prehistoric exhibits, and has made friends with Gregor Keretsky, a vertebrate paleontologist with an office at the museum. Caroline is serious about growing up to be a paleontologist, as her thirteen-year-old brother J.P. and their mother know. Caroline's closest friend from school, Stacy Baurichter, is from a much wealthier family than Caroline but shares the same mild level of eccentricity, desiring to be an investigative reporter. Caroline and Stacy imagine all sorts of mysteries for them to look into together, but a serious possible threat is about to emerge.
Caroline is curious about Frederick Fiske, who lives on the top floor of her apartment building. She knows every other resident well but hasn't received more than a curt nod from Mr. Fiske, and she's not pleased with his opaqueness. Then Caroline finds an opened letter in the apartment entryway's wastebasket, containing eye-opening information. A man named Carl Broderick wrote the letter to Mr. Fiske, suggesting he "eliminate the kids." Elsewhere, Mr. Fiske's mail indicated a peculiar interest in forensic toxicology. But the man lives alone; what kids would he kill? The dots connect when Caroline learns her mother is dating Mr. Fiske. If he dislikes children, would he do away with Caroline and J.P.? It's time for Caroline and Stacy to launch an investigation.
The girls find further circumstantial evidence that Frederick Fiske is a potential murderer, but Caroline is afraid to tell her mother. Joanna Tate wouldn't believe such a wild story. Caroline is usually at odds with J.P., an electronics whiz who takes pleasure in provoking his sister, but even he agrees something must be done when Caroline presents him with her case against Mr. Fiske. They're convinced it's a matter of time before Mr. Fiske poisons them, so they need to trick him into confessing now. Stacy, Gregor Keretsky, and Mr. Fiske are invited for a dinner party at the Tate apartment, where Caroline and J.P.'s plan to entrap Mr. Fiske will be put into action. How will the drama play out by evening's end?
Lois Lowry is famous for writing on sobering topics, notably her Newbery Medal winners Number the Stars (1990) and The Giver (1994). But she always did humor well: The Willoughbys, The Birthday Ball, and her Anastasia Krupnik and Gooney Bird Greene series are just a few examples. The One Hundredth Thing About Caroline isn't innovative or emotionally riveting, but offers laugh-out-loud moments, and the quirky characters are fun to be around. I'd read the sequel, Switcharound. If comedy is what you're after, you'll enjoy The One Hundredth Thing About Caroline.
