The Red House Mystery is a "locked room" whodunnit by A. A. Milne, published in 1922. It was Milne's only mystery novel. The Red House Mystery was immediately popular; Alexander Woollcott called it "one of the three best mystery stories of all time", though Raymond Chandler, in his essay The Simple Art of Murder (1944), criticised Woollcott for that claim, referring to him as, "rather a fast man with a superlative". Chandler wrote of Milne's novel, "It is an agreeable book, light, amusing in the Punch style, written with a deceptive smoothness that is not as easy as it looks ...] Yet, however light in texture the story may be, it is offered as a problem of logic and deduction. If it is not that, it is nothing at all. There is nothing else for it to be. If the situation is false, you cannot even accept it as a light novel, for there is no story for the light novel to be about."
