Mysterious murders take place one after another on the estate of the respected werewolf Shamura bel-al Sepio. The werewolf's relatives die, his servants die. Are these accidents or is there some kind of spell at work here? Or did agents of the Principality of Chaos, neighboring the state of Valibur, have a hand in this? There is something to puzzle over the fox-werewolf Khoja Nasledi. He is a notorious womanizer, but in other respects an ascetic, a teetotaler and a terribly nervous type. Khoja Nasledi has also been working as a private detective for a long time, and he seems to be doing a good job at it. But the task before him is very difficult.
