As mysterious things happen in and around their Chicago school, Petra and Calder use their knowledge of the painter Vermeer, their intuition, and their problem solving skills to retrieve a stolen painting. The book’s Illustrations contain clues that are revealed only upon close (and multiple) examinations. This quirky mystery is sure to please fans of E.L. Konigsburg’s From the Mixed-Up Files of Mrs. Basil E. Frankweiler.
