It's just before Christmas. Snow is falling outside the windows of Pelham, an isolated country house. Loveable, enthusiastic Luke Brightman disappears without trace from a locked room. His sister-in-law is convinced there's something supernatural at play, but her logical friend Jemima believes she can solve the mystery through deduction. She investigates secret passages, gothic crypts and strange amulets, but can she find the missing Luke? And can she explain the ghostly figure of the man with the lantern? Inspired by locked room mysteries, Christmas ghost stories and the Bedfordshire countryside, this comic mystery is part of the collection Tales from the Old World.
