How the impossible happened

In any murder mystery featuring an amateur sleuth, members of the police force are almost always too quick to jump to the wrong conclusions, if they aren't portrayed as being downright stupid. This cliche gets turned on its ear in Case for Three Detectives (1936) by Leo Bruce.

Bruce gives us a classic locked-room mystery, so common at that time. A group of people are guests at the home of Dr. Thurston and his wife. Soon after Mrs. Thurston goes up to bed, the others hear a scream. After her securely locked bedroom door is broken open, she is found with her throat cut. There is an open window behind her, and a knife is found in the yard. How did the murder happen? How did the killer get away? Who could have done it when the others were gathered in a room below?

The next day three famous amateur detectives show up: Lord Simon Plimsoll (patterned after Lord Peter Wimsey), Monsieur Amer Picon (Hercule Poirot) and Monsignor Smith (Father Brown). Also present is Sergeant Beef, the local police officer, who immediately declares that he knows who the murderer is and how the crime was committed. Nobody believes him, however, or even asks him to explain. He has been told by his superiors to allow the three distinguished detectives to complete their investigations before making an arrest, and so Beef sits in the background while Plimsoll, Picon and Smith do their thing in the manner fans of Dorothy L. Sayers, Agatha Christie and G.K. Chesterton will be familiar with.

In the end, each of the three detectives names a different murderer and explains a totally different manner in which the crime was committed. And each brilliant deduction seems entirely convincing. But then Sgt. Beef tells what really happened, and offers the proof that the other three lacked.

Bruce gives us four -- make that five -- possible solutions to a crime that seems to have no solution at all. His novel is a treat for any fan of classic mysteries, and especially for fans of Wimsey, Poirot and/or Brown.
