The prophet's business manager is missing and suspected of the murder. Ellery cannot solve the crime with the little information he has, but six months later in Long Island, New York, a neighbour of one of his university professors is found headless and crucified to a totem pole in the same way, in the new neighbourhood of the Egyptian prophet and his followers. This corpse is clutching a red piece from a game of checkers. The third victim is a millionaire yachtsman, similarly crucified.
