Case For Three Detectives by Leo Bruce

Mrs Thurston is an amiable, benevolent, harmless middle aged woman. She loves to entertain and play the hostess, one evening when she was playing her part as a hostess to perfection, sleep induces her to leave her party and retire to bed. A few minutes later the guests in her drawing room below hear blood curling screams of a woman, the party rushes upstairs only to find Mrs Thurston's bedroom bolted from the inside.

They break open the door and find the poor lady murdered, her throat has been slit and there is no sign of the killer, there are two windows in the room, but looking outside they see no one and the flower bed beneath the window is undisturbed. After a through search of the room no one is found hiding in the room and there is no indication of a secret entrance. Then, where did the killer go? pretty soon people realize that they have all just witnessed a locked room murder, a locked room murder is obviously out of the league of local police sergeant, Beef.

Enter Lord Plimsoll, Amer Picon and Monsignor Smith, three amateur detectives who will remind the reader of three very famous literary detectives, as the three detectives race against each other to solve the crime, Sergeant Beef sits contemptuously in the background shouting that he has the solution, but will anyone listen?
