Locked Room Murders is a bibliography containing a description of the problem and, separately, the solution to locked room and impossible crime novels and short stories.  It has been a classic in the locked room pantheon for over 40 years, beginning with a 1972 article by Bob Adey in The Armchair Detective. The first edition of Locked Room Murders, published by Ferret Fantasy in 1979, covered 1280 titles. The 1991 second edition, published by Crossover Press, covered 2019 titles. This revised version contains the same 2019 titles, but with corrections and additional references which have appeared since 1991.

A Supplemental Edition to Locked Room Murders was published in December 2019, including novels and short stories (with translations from sources outside the Anglosphere), films, TV series, graphic novels, and other media published since 1991. It does not contain any of the titles in the Second Edition, Revised.

There is no plan for Kindle versions of either book.
