In the foothills of the Alps sheep are being slaughtered, apparently by an enormous wolf. The story attracts national interest, including that of Adamsberg. Another thing that catches Adamsberg’s interest is that he thinks he sees a previous girlfriend, Camille, on the news coverage of the story.
When the ‘wolf’ kills her elderly friend Suzanne, Camille goes on the hunt with Suzanne’s adopted son Soliman and her sheepherder Watchee. It soon begins to appear that the wolf is being directed by a human, a madman, serial killer.
Adamsberg only gets fully involved in this story in the final third of the book. He applies his usual blend of vague intuition and clear observation, and along the way gets reacquainted with Camille.
This is an enjoyable read, with a good balance of suspense, humor, and human interest.
