After inquiry it was proved that a young and demented girl called Perrenette Gandillon believed herself to be a wolf and had done this horrible deed. She was caught by the populace and torn limb from limb. This case occurred in the Jura mountains in 1598.

Soon afterwards Perrenette's brother Pierre was accused of being a wer-wolf, and confessed that he had been to the witches' Sabbath in this form. His son George had also been anointed with salve and had killed goats whilst he was in animal shape. Antoinette, his sister, was accused of sorcery and of intercourse with the devil, who appeared to her in the form of a black goat. Several members of the Gandillon family were arrested, and in prison Pierre and George conducted themselves as though they were possessed, walking on all fours and howling like wild beasts.

Not long after the Gandillon family had been disposed of, one Jeanne Perrin gave evidence that she was walking near a wood with her friend Clauda Gaillard, who disappeared suddenly behind a bush, and that the next moment there came forth a tailless wolf which frightened her so much that she made the sign of the cross and ran away. She was sure that the hind legs of the wolf were like human limbs. When Clauda saw her again she assured Jeanne that the wolf had not meant to do her harm, and from this it was thought that Clauda had taken the shape of the wolf.

One of the best known of the wer-wolf trials concerns Jacques Rollet, the man-wolf of Caude, who was accused of having devoured a little boy.

He was tried and condemned in Angers in 1598. Rollet came from the parish of Maumusson, near to Nantes, and he carried on his practices in a desolate spot near Caude, where some villagers one day found the corpse of a boy of about fifteen, mangled and blood-bespattered. As they approached the body three wolves bounded into the forest and were lost to sight, but the men gave chase, and following in the animals' tracks, came suddenly upon a half-naked human being, with long hair and beard, his hands covered with blood and his teeth chattering with fear. On his claw-like nails they found shreds of human flesh.

This miserable specimen of man-animal was hauled up before the judge, and under examination he inquired of one of the witnesses whether he remembered shooting at three wolves. The witness said he remembered the incident perfectly. Rollet confessed that he was one of the wolves and that he was able to transform himself by means of a salve. The other wolves were his companions, Jean and Julian, who knew the same means of acquiring animal shape. All the particulars he gave as to the murder were accurate, and he confessed to having killed and eaten women, lawyers, attorneys, and bailiffs, though the last-named he found tough and tasteless. In other respects his evidence was confused, and he was judged to be of weak intellect, and though condemned to death was sent finally to a madhouse, where he was sentenced to two years' detention.

There was an epidemic of lycanthropy throughout this year, and on the 4th of December a tailor of Châlons was burnt in Paris for having decoyed children into his shop, a cask full of human bones being discovered in the cellar. For the space of a few years no notorious wer-wolf trials appear to have taken place, but the year 1603 was almost as prolific in this respect as 1598.

Information came before the criminal court at Roche Chalais that a wild beast was ravaging the district, that it appeared to be a wolf, and that it had attacked a young girl called Margaret Poiret in full daylight.[38]

A youth of thirteen or fourteen in the service of Peter Combaut deposed to the fact that he had thrown himself upon the said Margaret, whilst transformed into a wolf, and that he would have devoured her had she not defended herself stoutly with a stick. He also confessed to having eaten two or three little girls.
