Masterpiece Mystery Fair is foul and foul is fair in the hamlet of Much Deeping, where the Pale Horse Inn is run by a trio of enterprising witches, and the annual celebration of the town's witch trials of 1664 is about to commence. Arriving just in ... (more)time is Miss Marple, who has set her knitting aside to pursue the murderer of her old friend, Father Gorman. Armed with a list of names sent to her by the clergyman just prior to his death, Miss Marple follows clues as she joins the assemblage of guests and infiltrates the witches' inner circle. But when a fellow guest at the Pale Horse Inn is found dead, the unassuming sleuth must determine whether black magic or something even more sinister is at work.
