Agatha Christie 
The Murder on the Links 

The Murder on the Links is a work of detective fiction by Agatha Christie, first published in the US by Dodd, Mead & Co in March 1923 and, in the same year, in the UK by The Bodley Head in May. It features Hercule Poirot and Arthur Hastings. 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.
