Christie Agatha Christie 
Poirot Investigates (Hercule Poirot series Book 3) [EPUB ebook] 

First there was the mystery of the film star and the diamond… then came the "suicide" that was murder… the mystery of the absurdly cheap flat…a suspicious death in a locked gun room… a million dollar bond robbery… the curse of a pharaoh’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 will. What links these fascinating cases? Only the brilliant deductive powers of Hercule Poirot!
