The heavy iron clock struck twelve inside the dusty hall. Cold rain lashed against the tall windows of the manor. A silver dagger lay gleaming upon the expensive Persian rug. Lord Arthur Thorne crumpled silently onto the pale velvet chair. His frozen eyes stared blankly at the dark velvet curtains. The bitter scent of almonds drifted through the silent room. No living soul heard the final breath leave his chest. Somewhere deep within the house a single floorboard creaked loudly.
