Houston homicide detective Stuart Haydon receives photographs that he has never seen before: two portraits of his late father, two of a woman painting at an easel and standing on a Mexico City street, and one of Haydon himself, with a bullet entering his head drawn on the photo. His search to solve the riddle of these pictures leads to a Mexican professor of anthropology whose interest in pre-Columbian civilization has crossed from the scholarly into the psychotic. Following the intended killer's trail, Haydon travels to Mexico City, where he learns that his patrician father carried on a long affair with the mother of the killer, a fiery, beautiful Mexican artist, in whose studio an explosive denouement takes place. Unfortunately, Lindsey's narrative drags and fails to satisfy.
