Cold rain lashed the old manor’s fogged glass window panes. A sharp scream split the tense hush of that night. Guests dropped their champagne flutes frozen mid-toast right that instant. None had noticed their wealthy host leave three full hours. The family’s sharp lawyer volunteered to check the west wing. He twisted the old library’s rusted heavy iron entry handle. Thick warm blood pooled across the polished antique oak floor. The host’s crumpled body lay slumped over his mahogany desk. A silver letter opener jutted straight from his bare throat. No stray footprints marked dust by the locked back exit.
