The storm raged outside, hammering rain against the ancient windows of Blackwood Manor with unrelenting, furious force. Inside, however, a chilling silence had fallen over the grand ballroom, broken only by the creak of settling timbers. Lord Ashworth lay sprawled near the untouched mahogany table, his silk smoking jacket stained with crimson, a profound stillness upon him. A single, ornate letter opener protruded from his chest, glinting dully in the weak light filtering through the heavy velvet curtains. Inspector Davies stepped carefully over the Persian rug, his keen eyes scanning the scene for any detail others might have missed. The air hung thick with the scent of expensive perfume mixed strangely with the metallic tang of newly spilled, unfortunate blood. No signs of forced entry disturbed the solid oak doors, suggesting the killer was certainly someone known intimately to the household. A forgotten teacup sat upon a nearby side table, its contents still warm, betraying a recent, unexpected visitor’s presence. The terrified butler wrung his trembling hands, his face a mask of pale horror at the terrible event he had witnessed. This wealthy recluse, known for his eccentric habits, now rested eternally, a dark mystery veiled by family secrets and old money.
