Ghostly image leaves experts baffled

AN eerie image of a figure in period costume at a Scottish castle has spooked experts conducting the biggest ever investigation into photographic evidence for ghosts.

The picture, taken in May 2008, appears to show a man or woman in a ruff peering out of a barred window at Tantallon Castle.

No mannequins or costumed guides are employed at the castle, and three photographic experts have confirmed that no digital trickery was used on the photo.
