This episode presents three unsolved supernatural mysteries: the vengeful spirit of "Bloody Mackenzie" haunting Edinburgh’s Greyfriars Kirkyard, a ghostly figure in period dress captured on CCTV at Hampton Court Palace, and the mysterious faces appearing in the concrete floor of a Spanish home. The host recounts the history behind each location, from 17th-century political executions to the tragic death of Catherine Howard, and details the eerie phenomena reported by witnesses, including physical injuries, unexplained cold spots, and paranormal activity that persists decades later.
