On a dark stormy night the butler found the dead body of the rich owner lying on the study floor. Blood stained the expensive carpet around the victim while a broken window suggested the killer had escaped into the night. Rain poured heavily outside as the inspector questioned all the shocked household staff about their whereabouts during the fatal incident. Everyone present in the mansion had a possible motive for the crime making this case particularly difficult to solve quickly.
