Tom Ripley is quietly living in luxury at his chateau at Villeperce. He has a past, however, that would not bear too much close scrutiny. He is certain that he has covered his tracks where murder and forgery are concerned. But when David Pritchard moves in next door, Ripley fears that his secrets may be discovered. Pritchard is a fellow American whose boorishness marks him as something of Ripley's alter-ego. Inexplicably familiar with all the incriminating details of Ripley's past, Pritchard is determined to expose him. He shadows Ripley's every move, first spying on him at home in France and then following him to Morocco. Tensions build on their return to Villeperce as Pritchard sets out to locate a body Ripley would prefer remain hidden in a nearby river.
