Agatha Christie is known throughout the world as the Queen of Crime. Her books have sold over a billion copies in English with another billion in 100 foreign languages. She is the most widely published author of all time and in any language, outsold only by the Bible and Shakespeare. She is the author of 80 crime novels and short story collections, 19 plays, and six novels written under the name of Mary Westmacott.

An urgent cry for help brings Poirot to France. But he arrives too late to save his client, whose brutally stabbed body now lies face downwards in a shallow grave on a golf course.

But why is the dead man wearing his son's overcoat? And who was the impassioned love-letter in the pocket for? Before Poirot can answer these questions, the case is turned upside down by the discovery of a second, identically murdered corpse...
