The heavy rain hammered against the tall, arched windows of Blackwood Manor, mirroring the storm that raged inside Eleanor's heart. She stood alone in the cavernous library, staring at the portrait of her late husband, Lord Ashworth, with cold fury. A sudden, sharp crack of thunder made her jump, and she spilled her glass of expensive sherry onto the rug. Cursing softly, she knelt to blot the stain, noticing a strange, dark smear near the edge of the Persian carpet. It wasn't wine; it was thick, red, and sticky, and it led towards the heavy velvet curtains on the wall. With trembling hands, she pulled the heavy fabric aside, revealing a sight that would forever haunt her deepest, darkest nightmares. There, slumped against the cold stone sill, was the lifeless body of her brother-in-law, Detective Inspector Marcus Thorne, eyes wide. A silver letter opener, a family heirloom, protruded from his chest, glinting wickedly in the flickering candlelight of the room. Eleanor screamed, a long, piercing sound that echoed through the empty halls, but no one was left alive to hear.
