Haunting in The Old Citadel

The sisters especially wanted to see "The Lost Cadet", a ghost who is said to haunt the hotel. He appears to be a teenager and is reported to be a happy chap. He supposedly only has half a head, from his eyebrows up there is nothing as if a cannon ball took the top off. Some employees call him "Half Head" but since he causes no mischief they are only startled by him and not frightened. The sisters could not find him but can you find them in the atrium or courtyard?
