One, Two, Buckle My Shoe // Patriotic Murders // An Overdose of Death — Agatha Christie

It was shortly after his 12:30 appointment that Dr. Morley was found with a bullet through his right temple. The gun was on the floor beside him. The authorities were satisfied that the amiable old dentist had shot himself. Hercule Poirot was not. But who could have murdered him? One of Dr. Morley's glamorous patients? His hard-drinking partner? His secretary's disgruntled boyfriend? All Poirot has is a hunch, too many clues and a killer who will not be satisfied with only one victim.

THE SUICIDE OF A HAPPY MAN

Why should a perfectly respectable and successful dentist kill himself? Was it in response over administering a fatal dose of drugs to his mysterious patient? Or was there some other explanation hidden in the private life of those around him? Or was it suicide at all?

These questions work Hercule Poirot's “little gray cells” overtime in a baffling case where the loves of a dozen men and women are entwined with politics, cloak-and-dagger intrigue, and blackmail…with the life of one of England's great men at stake.
