The image of a ghostly figure in ancient dress was captured by a security camera at Hampton Court Palace in southwest London, England. Actually recorded sometime in October, the ghost was not seen on the video until security guards reviewed tapes because a fire door had been inexplicably opened. On the video, which has not yet been released, the ghost appears on the screen in the doorway and closes the door. "We're baffled too - it's not a joke. We haven't manufactured it," said Vikki Wood, a Hampton Court spokeswoman. The Palace has long been known for its haunting activity.
