At Lincoln, Margaret accused her mother of witchcraft, while Phillipa admitted to witchcraft on behalf of herself, Margaret and Joan. The sisters said they had entered into communion with familiar spirits that had assisted them with their schemes. The mother's familiar was a cat named "Rutterkin". The women admitted that they stole the glove of Lord Ros and gave it to their mother, who had dipped it in boiling water, stroked it along Rutterkin's back, and pricked it. Combined with some incantations this supposedly caused Lord Ros to become ill and die. An attempt to harm Lady Katherine, the Earl's daughter, had failed when it was found that "Rutterkin" had no power over her. The women had also taken some feathers from the quilt of Rutland's bed and a pair of gloves. By boiling these in water mixed with blood they cast spells to prevent the Earl and Countess from having any more children. Both women admitted to experiencing visions of devils and that their familiar spirits visited them and sucked at their bodies.
