Decades before "The Witcher" and George R. R. Martin’s universe, Fritz Leiber ruled the world of sword-and-sorcery. The fantasy duo of grandmaster antiheroes—the barbarian Ruth the Cutthroat, who can sing quite well, and the nimble thief who knows magic tricks—was originally conceived by the author as a subtle parody of Howard’s Conan. But it quickly found its own unique fate and, just as quickly, won fame. In the grim world of Nevon Fafhrd and the Grey Mouser, they plunge without hesitation into the most incredible predicaments, work miracles of survival, and never lose their humanity or their sense of humor.
