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

But why is the dead man wearing an overcoat that is too big for him? And for whom was the impassioned love letter in the pocket? Before Poirot can answer these questions, the case is turned upside down by the discovery of a second, identically murdered corpse.?

Agatha Christie is the most widely published author of all time, outsold only by the Bible and Shakespeare. Her books have sold more than a billion copies in English and another billion in a hundred foreign languages. She died in 1976.
