Edogawa Ranpo is recognized as the father of Japanese detective mystery novels. His works have both the rigorous conception of the "original style" and the fantasy of the "changed style". The cases are interlocking and highly suspenseful; the narrative is filled with a sense of monster and absurdity at all times, making people feel as if they have entered a twisted alien world and enjoy the beauty of horror. This has become a source of inspiration and material for various films, television and animation. This "Ranpo Masterpiece Short Story Collection" series, sorted by publication time, collects all the short stories he created in full. There are thirty-five articles in total, and the attached "Lady Rose" is the final unfinished draft.
