Cold rain lashed the gabled stone manor’s tall dark windows. Eight shaken guests huddled around the old library’s crackling fireplace. The host’s young daughter noted her father missed the gathering. A quiet footman volunteered to climb the west wing stairs first. His sharp frantic scream echoed down the cold uncarpeted halls. A sharp silver letter opener pierced the host’s still throat. The heavy oak bedroom door locked tight from the inside. The sealed stained-glass window let no one enter or leave. No guest claimed to have left the library all evening. A crumpled blackmail note slipped from beneath his stiff hand.
