Brotherhood of the Wolf
While investigating another victim, Fronsac finds a fang made of steel. A traumatized child witness swears that the beast is controlled by what seems to be a human master. As the investigation proves unfruitful, the king's weapons master, Lord de Beauterne, arrives to put an end to the beast, and Fronsac is sent back in Paris. He realizes that the beast is actually an instrument of a secret society: The Brotherhood of the Wolf, which is working to undermine public confidence in the king and ultimately take over the country. Back in Gévaudan, the attacks by the real beast continue, and Fronsac returns to put an end to the beast's killings. At a secret rendezvous with Marianne, they are attacked by the beast, where it mysteriously refrains from attacking her.
