The discovery of the body of a young, red-haired school mistress, lying in a pig-pen with her face half-eaten away, is the beginning of a new investigation for Charlie Woodend. But it is to be an investigation he is soon ordered to abandon when Helen Dunn, the daughter of Wing Commander Dunn - and a pupil at the school where the dead woman taught - suddenly vanishes into thin air. While Woodend and Rutter race against time in the desperate hope of finding the girl alive, Woodend's bagman, Monika Paniatowski, continues to work on the murder, under the supervision of the mysterious Chief Inspector Horrocks, a Scotland Yard man who seems to have only a mild interest in finding the killer. Are the two cases connected? Woodend begins to wonder. And if they are, who is it who seems to be blocking both investigations at every turn?
