The rain hammered against the tall windows of old Blackwood Manor as guests gathered for dinner that fateful stormy evening. Lord Ashworth raised his crystal glass high and proposed a warm festive toast to celebrate his daughter's engagement announcement tonight. Nobody noticed that the butler's pale hands were trembling slightly as he carried the silver soup toward the long table. At precisely nine o'clock, a terrible piercing scream suddenly echoed through the grand quiet halls and shattered the celebration completely. The trembling maid discovered Lord Ashworth lying completely motionless on the cold study floor, his glassy eyes staring at nothing. A gleaming silver letter opener protruded gruesomely from his chest, and a half-finished glass of expensive old brandy sat nearby. Every guest inside the isolated old house had a compelling motive, and every single one swore they were utterly innocent. Detective Inspector Marsh arrived promptly at midnight, his sharp grey eyes already quietly cataloguing every suspicious detail he encountered there. The violent storm had completely washed out the only access road, trapping the killer among them until morning finally came. Somewhere inside that dark sprawling house, a cold murderer was waiting patiently for the next perfect opportunity to strike again.
