The Wright 3
Blue Balliett
 Calder's friend Tommy Segovia, who moved away a year before, has moved back to Hyde Park, Chicago. He is immediately jealous of Calder and Petra as they received the "glory" of saving a Vermeer painting in the previous book (Chasing Vermeer). Tommy feels that he deserves something as well. In his first new day of class, Ms. Hussey announces that the world-famous Robie House is soon to be demolished, which she considers to be murder. The class takes a field trip to the house, and both Calder and Petra discover that there are many secrets concerning the building that they were not aware of. After Tommy learns to tolerate Petra, the three (who call themselves 'The Wright 3') work to save the house, even breaking into it toward the end. Tommy finds a fish talisman in the Robie House garden and realizes it is worth a lot of money. Finally, after saving their own lives against a band of robbers in the Robie house, they manage to save that of the house. In almost every illustration, there is a drawing of a fish (referring to Frank Lloyd Wright's lucky talisman) that is usually hidden by nature. They appear in each chapter with the fibonacci sequence. On one of the last illustrations, a dragon can be found, expressing the change from carp to dragon in the story. Toward the bottom of the last picture there are footprints from the invisible man. In several images, a face can be spotted.
