Alison Device alleges in her confession that her familiar (Anonymous 186) appeared to her in the form of a black dog this last March, when she tried to buy some pins from a pedlar, John Law, and was refused. Her familiar asked what she would have him do to Law, and she instructed him to lame him. Law fell down in the road.(R3v-R4)

John Law gives deposition alleging that this last March, he walked through Colne with his pack of wares and there met Alison Device. Device demanded pins, but he would not give her any, and she became angry. When he left her, he fell down lame. After some time, he was able to make it to a nearby ale-house, and lay there in great pain unable to stir his limbs. He saw a great black dog standing by him, with fiery eyes, large feet and a "terrible countenance." Device came shortly thereafter, looked at him for a short time, and left. He claims that he was tormented day and night by Device thereafter, and remained lame.(R4v)
