Chasing Vermeer is a 2004 children's art mystery novel written by Blue Balliett and illustrated by Brett Helquist. Set in Hyde Park, Chicago near the University of Chicago, the novel follows two children, Calder Pillay and Petra Andalee. After a famous Johannes Vermeer painting is stolen on route to the Art Institute of Chicago, Calder and Petra work together to try to recover it. The thief publishes many advertisements in the newspaper, explaining that he will give the painting back if the community can discover which paintings under Vermeer's name were really painted by him. This causes Petra, Calder, and the rest of Hyde Park to examine art more closely. Themes of art, chance, coincidence, deception, and problem-solving are apparent.
