First published by Dedalus in 1997, this locked-room detective novel from 1908 is a classic of early 20th-century detective fiction. At the heart of the novel is the enigma: how could a murder take place in a locked room which shows no sign of being entered? The novel is also about the rivalry between detective Frederick Larson and a young investigative journalist, Rouletabille. Larson finds a suspect who is put on trial, only to have him cleared by Rouletabille, who dramatically reveals the identity of the real murderer. The Mystery of the Yellow Room is a novel which consciously tries to outdo the traditional detective novel with classic intellectual conundrums.
