Muller had been sent to spy on the first alien race mankind had ever encountered. But they discovered him, and cursed him with a terrible power that made his presence unbearable to his fellows, theirs to him.
Now, alienated and embittered, he chooses to live out his life in an abandoned city on a long-dead planet. But men must enter Muller's murderous labyrinth and try to lure him out, for humanity still needs his unique talents.
