Three people receive the same mysterious letter, a curious book shows up, and a Vermeer painting is stolen. Coincidence? Not according to Calder Pillay and Petra Andalee. Then the art thief challenges the world to take a closer look at Vermeer’s work, but for Calder and Petra, there are more personal reasons for solving the mystery. Using secret codes and intuition, the unlikely pair forge a friendship and are determined to get to the bottom of things—no matter how dangerous things may get. Because neither can rest until Vermeer’s A Lady Writing is returned where she belongs. Readers can also find an interactive mystery in the book's illustrations. Read Balliett's The Wright 3 and The Calder Game for more adventures with Calder and Petra.
