Supernatural detective Ishmael Jones knows all there is to know about solving mysteries. Together with his love and partner in crimes, Penny Belcourt, he specializes in cases of the weird and uncanny.

Lucas Carr went to Glenbury Hall, an old country manor house turned hotel. He signed in at reception, took his key, and went upstairs to his room. But he never got there. Somehow he vanished along the way, with not a single clue to suggest what might have happened to him.

Lucas belonged to the same mysterious organization that employs Ishmael and Penny, so they are sent in to solve the mystery. But when they arrive at grim and isolated Glenbury Hall, they discover it has a reputation as one of the most haunted old houses in England. None of the usual headless monks or walled-up nuns—just stories of lost souls that dance with the statues in the grounds, doors that won’t stay shut, rooms that aren’t always there, and something that prowls the house in the early hours, endlessly searching—and they say it crawls.

Does Lucas’s disappearance have something to do with the organization or the Hall’s haunted past? Ishmael and Penny have to work their way through a series of mysterious clues and misleading suspects, uncovering secret after secret, before they finally arrive at a truth that no one suspected.

The problem with history is that it’s not always content to stay in the past.
