The rain lashed against the windows as Inspector Whitmore stepped into the dimly lit library. Lord Pembroke lay sprawled across the Persian rug, a single bullet wound clearly visible in his chest. A bloodstained letter clutched in his hand bore the name of a vanished woman, Eliza Thorn. The butler claimed he was in the wine cellar, polishing glasses when the shot rang out. Outside, thunder roared as the storm trapped everyone within the manor’s ancient, creaking halls. Whitmore’s gloved fingers traced a smudge of lipstick on the victim’s collar, crimson and fresh. No signs of struggle, yet the window stood open, its latch unfastened from the inside. A shattered teacup near the fireplace hinted at hurried footsteps or a desperate escape. The widow’s trembling voice had whispered, “He was poisoned by someone he trusted,” before fainting. Inspector Whitmore frowned, noting inconsistencies in every alibi, each one crumbling like the storm outside.
