Sly (a.k.a. Sylvia) has newly set up shop as a neighborhood detective, and the advice from Kirkus Reviews is plain and simple: "Clear some shelf space" for this funny, engaging series.With each zany mystery brought to her by friends and parents—this time involving soccer, ballet, swimming, and basketball—Sly uses her keen observation and reasoning skills to solve the case, while young readers will get a kick out of guessing the solutions alongside her.Best-selling author Donna Jo Napoli and her son, Robert Furrow, and illustrator Heather Maione, have created an enormously likable detective who is smart, spunky, and very witty!
