Jack-in-Irons

Jack-in-Irons is a spectre said to haunt the lonely roads of Yorkshire, England. A tall, Demonic figure draped in chains, the Jack-in-Irons reportedly jumps out at travellers and gives them a fright. The chains make Jack-in-Irons an unusual spectre, for few ghosts have them in folklore and legend, despite a popular portrayal of ghosts in chains in art and literature (see Haunting of Athenodorus).
