A self-proclaimed white witch has been called to Edinburgh Dungeon to exorcise a ghost said to be haunting the attraction's boat ride.
There have been a number of problems with the boat since the dungeon opened on Friday April 13th and it has broken down numerous times, including nine times in August alone.
Kevin Carlyon is also going to Scotland to lift the curse on Shakespeare's play Macbeth by summoning the spirit of the real King Macbeth of Scotland, who ruled from 1040 until 1057.
Kevin, from St Leonards-on-Sea, East Sussex, said: "I will have to set up an altar and perform a series of powerful incantations using a force which I prefer to call 'earth magic', in order to rid the Dungeon of any malevolent spirits.
"My guess is that the choice of Friday 13th for their opening day really did unleash a malign presence."
Emma Ross, dungeon boss, said: "We've still got engineers and technicians working overtime on our boat ride but their remedies have thus far all proved temporary."
She said that, although the problem appears to have been fixed, they have still asked Kevin to carry out the exorcism tomorrow as 'extra insurance'.
While in the city, Kevin also intends to go to Edinburgh Castle where he will call upon the spirits to determine whether the Stone of Scone or Stone of Destiny is really a fake or not.
Controversy has surrounded the Stone, which was returned to Scotland from England on St Andrew's Day 1996, with claims it is a fake.
