Matthew Hopkins, self-appointed 'Witchfinder General', led a campaign against alleged witches in the 1640s, resulting in numerous executions. Residing in Mistley, he is believed to have died in 1647. His association with The Mistley Thorn, where he purportedly conducted interrogations, has led to reports of his ghost appearing in the hotel. Guests and staff have described encounters with a stern-looking man in 17th-century attire, sudden chills, and an oppressive atmosphere in certain rooms.
