The Fiend with Twenty Faces, the first in the Boy Detectives series by Japan's master of mystery Edogawa Rampo, helped create a new genre in Japan and enthralled thousands of young readers.
When 1930s Tokyo is threatened by a master thief who claims he can take on any disguise and stymie any matter of law enforcement, the people of the city have nowhere else to turn but Japan's greatest detective, Akechi Kogoro. Unfortunately for Tokyo, however, Akechi Kogoro is off on overseas business, so it becomes the job of his 12-year old assistant, Kobayashi Yoshio, to track down the thief and desperately keep him at bay until his mentor returns.
In the spirit of Sir Arthur Conan Doyle's Baker Street Irregulars, The Fiend with Twenty Faces is a classic mystery tale by a world-renowned author filled with disguises, tricks, "A-ha!" moments, and spiced with a unique Japanese flair. Will Kobayashi's intrepid band of little detectives be able to outwit the nefarious fiend, or will Tokyo be forever at the mercy of the face-swapping phantom?
