Rùzový Hubert plot
Things get nasty at night at Chelford Castle. Since Abbot Hubert was murdered there some 400 years ago, his ghost haunts the abbey during the dark nights. Each time there is a devil's howl as his ghost haunts through the wisps of mist. Sergeant Putler, Scotland Yard's most intrepid and successful investigator, will delve into the case at Richard Chelford's request. However, his brother, Lord Henry, is more interested in the legendary golden treasure that must have been hidden somewhere on the estate since the death of Abbot Hubert.
