James was convinced that the storms which kept him and his queen so long from meeting were the results of diabolical agencies. After his return to Scotland, suspicion fell on a dangerous gang of witches and warlocks at Tranent, and the king resolved to inquire into the whole case, with the laudable design of getting rid of such wicked subjects should he find them guilty. A man named David Seytoun, who held the appointment of deputy bailiff of Tranent, had a young female servant named Geillis Duncan, celebrated among the town's people for her skill in curing diseases. Seytoun, becoming suspicious that she was in league with Satan, questioned her closely without receiving satisfactory answers. Not to be defeated, he first put her to the torture, which he thought he had a right to do in virtue of his office, and then searched her person for devil's marks. One of those sure tokens of witchcraft being found on her throat, she was committed to prison. There she made a full confession, in which many persons were implicated. She admitted that the cures effected by her were brought about by means of witchcraft. Of those said to have been associated with this woman in her guilty deeds, the most noted were Dr. John Fian, sometimes called John Cunningham, and three women, named Agnes Sampsoun, Euphame Mackalzeane, and Barbara Napier. Fian was a schoolmaster at Tranent, a small town on the south side of the Firth of Forth, and about nine miles east of Edinburgh. He admitted that he was an agent of the evil one. One night, he said, the devil appeared to him, and induced him to become his servant, under the promise that he would never want if he served him faithfully and well. The offer being tempting, the unscrupulous doctor became an instrument of evil. That there might be no mistake about the bargain, the devil put his mark on Fian's person. From that time the doctor was a sorcerer: he was often carried away in the night to visit distant places of the world, and was present at, and took part in, all the nightly meetings of witches held in the Lothians. He rose so high in the devil's favour, that he was appointed registrar and secretary of the conventions. One night Fian was carried through the air to North Berwick, where he found a number of witches and sorcerers assembled listening to Satan preaching to them from a pulpit. He implored them to give up all slavish fears of him; promised them great rewards so long as they were his servants, and assured them, that so long as they had hairs on their bodies they would receive no injury. He exhorted them to do all the evil they could, and to eat and drink and be merry. One night when Fian was riding home along a dreary road, in danger of losing his way, Satan came to his assistance, and put four candles on the horse's ears, which enabled the traveller and his servant to see as well as if it were day.
