Locked Room Mystery - Authors and Works

Authors and Works

The acknowledged master of the locked-room sub-genre was John Dickson Carr, who also wrote as Carter Dickson.

His novel The Hollow Man was voted the best locked room mystery novel of all time by 17 authors and reviewers, although Carr himself names Gaston Leroux's The Mystery of the Yellow Room as his favorite.

The Hollow Man gives an explicatory recipe for crime writers: Chapter 17 of the book consists of a theoretical digression entitled "The Locked-Room Lecture". In it, Dr Gideon Fell (the detective) gives an extensive explanation of how the murderer is able to deceive everyone else (at least until the riddle is finally solved). How, for example, Fell asks, can the perpetrator create the impression of a hermetically sealed chamber when in fact it is not? What means are there of tampering with a door so that it seems to be locked on the inside? This is just one of the answers—and, as it happens, the most simple one—given by Fell:

... An illusion, simple but effective. The murderer, after committing his crime, has locked the door from the outside and kept the key. It is assumed, however, that the key is still in the lock on the inside. The murderer, who is first to raise a scare and find the body, smashes the upper glass panel of the door, puts his hand through with the key concealed in it, and finds the key in the lock inside, by which he opens the door. This device has also been used with the breaking of a panel out of an ordinary wooden door.

There are six other categories of locked room as expounded by Dr. Fell. Clayton Rawson in Death from a Top Hat describes nine. Anthony Boucher in Nine Times Nine and Derek Smith in Whistle Up the Devil are two other authors to offer a comprehensive overview of locked-room methods. The reader is warned: while these lectures may well be erudite and educational in their own right, their true purpose in each case is to divert attention from the method actually used in the book.
