Eerie things are happening at Chelford Castle at night: Since the murder of Abbot Hubert some 400 years ago, his ghost is said to haunt the abbey on dark nights. Devilish howls can be heard as he wanders through clouds of fog. Sergeant Putler, Scotland Yard's most intrepid and successful detective, is hired by Richard Chelford to investigate the case. His older brother, Lord Henry, is much more interested in the legendary treasure of gold that is said to have been hidden somewhere on the grounds since Hubert's death. The situation escalates when Henry's secretary, Mary Brown, disappears without a trace one night, and a man in a monk's habit with a knife appears in Richard Chelford's bedroom, intent on killing him. Meanwhile, Sergeant Putler chases the mysterious monk's terrifying screams through the foggy and eerie night...

At the center of the crime story is the very large Kremp family, living in the family villa with other relatives and a subtenant. The parents had four adult children, two sons and two daughters, one of whom recently died. The investigation focuses on the recent death of their son Jan. The young man was considered the family "fool", whom no one except his mother liked, because he played various mischievous tricks on everyone. However, his death, as Captain Exner investigates, was not an unfortunate accident, but a murder. Who could have been interested in his death? Was the murderer someone from the immediate family? Captain Exner is looking for a motive...
