Neighbour and former friend Grace Thurlow testified that when her son Davy was sick, she asked for Kemp's help. Davy temporarily recovered from his illness and Thurlow believed that Kemp had cured him. Some time later, Thurlow and Kemp argued over the care of Thurlow's baby daughter Joan. At a few months old, Joan fell from her cradle and died of a broken neck.Brooklyn Museum When Thurlow became lame, she again asked for Kemp's help. Kemp agreed to heal her for 12 pence. Thurlow got better but then refused to pay Kemp her fee, saying she could not afford it. The two women argued again and Kemp threatened to get even with Thurlow, who became lame again. Thurlow testified that since that quarrel, either she or her son had suffered. She blamed Kemp for her son's illness, her own lameness, and the death of her baby. Thurlow complained to the magistrate and an investigation followed.
