Shortly after Hercule Poirot’s visit, a dentist lies murdered in 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?
