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.

Few people realize that the fame of Leonardo da Vinci’s 16th century painting was created in large measure by its theft in the 20th century. The lively narrative alternates between the artist and the search for the missing painting. Sardonic illustrations add humor and interest to this well-documented and fascinating story.
