It begins with a photograph Charlie takes for school. His shot of a swimming otter is striking -- and baffling, because there have been none in the area for years. As Charlie tries to find out where the animal came from, he keeps crossing paths with the unnerving Peter Luttrell. Why is Peter so fascinated with an ordinary photograph? Why do Peter's classmates call him 'Evil Eye'? And why do the mysterious otter's tracks lead directly to Peter's yard?
