A true detective answers at least one of three questions: “Who? How? For what?" And it doesn’t matter where and when the action takes place: in steam-punk Britain, in modern Russia, ruled by vampires, or in 19th-century France. Whether you are a galactic policeman or a German landsknecht, until you find the answers to these “eternal questions,” you will not find the criminal. Ten fascinating stories from the best science fiction writers of several generations. Ten puzzles set in unimaginable worlds. Only new stories written specifically for this collection. Forward, reader! The game begins!..
