I missed this story somehow. It seems that security cameras at Hampton Court Palace in London, home of King Henry VIII in the 16th century, have caught a ghost on film.
On several occasions security guards were alerted to an open fire door in an exhibition area of the palace. After securing the door each time, they returned to their office to view the CCTV footage to see who had opened them.
On the first occasion the footage showed the doors flying wide open, but no evidence of why they had.
On the second, the guards were stunned when a ghostly figure in period dress suddenly appeared on the screen and closed the doors. The same thing happened on a third day, but again no figure appeared.
Here’s another story on the event. and it includes a slideshow of the pictures and a link to the video, though I can’t get the video to work.
