The Witches of Angel's Rise (S22E06)

Every year, the community of Angel's Rise celebrates the Psychic Fayre, a tradition established by the Saint-Stephens family to honor their deceased daughter. This popular event draws mediums, psychics, and enthusiasts of the mystical arts. However, when a corpse is discovered adorned with ritualistic markings just before the festival begins, Barnaby is compelled to delve into the realm of the supernatural to uncover the murderer.
