When Calder Pillay travels with his father to a remote village in England, he finds a mix of mazes and mystery . . . including an unexpected Alexander Calder sculpture in the town square. Calder is strangely drawn to the sculpture, while other people have less-than-friendly feelings towards it. Both the boy and the sculpture seem to be out of place . . . and then, on the same night, they disappear! Calder's friends Petra and Tommy must fly out to help his father find him. But this mystery has more twists and turns than a Calder mobile . . . with more at stake than first meets the eye.
