A dentist lies murdered at his Harley Street practice?
The dentist was found with a blackened hole below his right temple. A pistol lay on the
floor near his outflung right hand. Later, one of his patients was found dead from a lethal
dose of local anaesthetic. A clear case of murder and suicide. But why would a dentist
commit a crime in the middle of a busy day of appointments?
A shoe buckle holds the key to the mystery. Now ? in the words of the rhyme ? can Poirot
pick up the sticks and lay them straight?
