Cold November rain battered the tall gothic windows of Blackwood Manor while thunder rattled the ancient wooden floorboards beneath me. Lord Arthur lay motionless beside the roaring fireplace with an ornate silver dagger protruding straight from his silent bleeding chest. I knelt carefully upon the expensive Persian rug to examine the dark crimson stain spreading slowly toward his polished shoes. Clutched tightly inside his cold stiff fingers was a torn velvet ribbon smelling faintly of jasmine perfume and bitter almonds. Every single heavy oak door remained bolted from within, meaning the ruthless killer was still hiding somewhere inside this house. Suddenly, the flickering brass chandelier went completely dark as soft footsteps echoed menacingly down the narrow corridor just behind me.
