Sir William Magnay

During a ball at Wynford Place one of the guests goes missing, a man with a unsavory reputation. When his body is discovered a day later in a locked room at the top of a mediaeval tower attached to the manor house it at first looks like a case of suicide. But as events unfold suspicion is thrown on first one and then another of the guests and household until the final solution is revealed to… The Hunt Ball Mystery.
