«Hercule Poirot 3-Book Collection 1» by Agatha Christie

The first three Hercule Poirot books see the former Belgian policeman tempted out of retirement to solve a series of outlandish murders in Britain and France, assisted by the redoubtable Captain Hastings, setting him on the path to becoming the World's Greatest Detective!
THE MYSTERIOUS AFFAIR AT STYLESAgatha Christie’s first ever novel. With impeccable timing Hercule Poirot, the renowned Belgian detective, makes his dramatic entrance on to the English crime stage.
MURDER ON THE LINKSAn 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.
POIROT INVESTIGATESFirst there was the mystery of the film star and the diamond… then came the ‘suicide’ that was murder… the mystery of the absurdly chaep flat… a suspicious death in a locked gun-room… a million dollar bond robbery… the curse of a pharoah’s tomb… a jewel robbery by the sea… the abduction of a Prime Minister… the disappearance of a banker… a phone call from a dying man… and, finally, the mystery of the missing willl.
What links these fascinating cases? Only the brilliant deductive powers of Hercule Poirot!
