Shadow of Fu Manchu, The
Fu Manchu was an evil Chinese physician bent on revenge after his wife was accidentally killed by a British officer during the Boxer Rebellion. Fu Manchu might have revolutionised science but chose the path of evil instead. Some of the weapons he devised included a snake in a cane handle, killer fungus and a green mist, which was delivered in letters. Once the letter was opened, green mist filled the room and killed everyone instantly.
