Poirot and Hastings are on holiday in Deauville and receive a visit from Paul Renauld, who believes he's being cheated by Chileans. Renauld is kidnapped and his body is later found buried in a new golf bunker. French detective Giraud unwisely challenges Poirot to catch the killer before he can. Meanwhile, Hastings is diverted by love - he has fallen heavily for an actress called Dulcie Duveen. Dulcie has a twin sister called Bella. And one of them appears to be mixed up in the killing of Renault.
