Yeah, the gambler cheated so they cut orf his hand.
It is thought that there are two wandering spirits: the Grey Lady, who is searching for her child; and the Demented Whist Player who is tormented by the loss of his hand, severed in a card game due to cheating. In the House of Lords is a mummified hand discovered in the 19th Century, which may have belonged to the ghost. In March 2004 it was stolen feared never to be returned but reappeaed in mysterious circumstances 6 weeks later.
