Locked Room Murders – 20 Solutions

From Robert Adey's Locked Room Murders (Ferret Fantasy, London 1979)

Major discussions on the subject of locked room murders are to be found in Carr's The Hollow Man, Rawson's Death from a Top Hat and Holmes' Nine by Nine.

There appear to be some 20 different ways in which a locked room can be breached.

Analysis of solutions

4 Mechanical and other devices.

5 Animal.

7 Victim killed earlier but made to appear alive later.

8 Presumed dead but not killed until later, e.g., by the first person to enter the room.

  A further mystery is the price and rarity of the much enlarged edition from Crossover Press 1992. A copy on Canadian Amazon (often a home for awesome prices) at $10000 seems to have now vanished...
