In writing the book, King James was heavily influenced by his personal involvement in the North Berwick witch trials from 1590. Following the execution of a notorious sorcerer in the year 1591, the news of the trials was narrated in a news pamphlet titled "Newes from Scotland" and was included as the final chapter of the text. The book endorses the practice of witch hunting in a Christian society. James begins the book: The fearefull aboundinge at this time in this countrie, of these detestable slaves of the Devil, the Witches or enchanters, hath moved me (beloved reader) to dispatch in post, this following treatise of mine (...) to resolve the doubting (...) both that such assaults of Satan are most certainly practised, and that the instrument thereof merits most severely to be punished.
