Thick fog blanketed Blackwood Manor. Inside, the grand clock chimed. Lord Reginald sat very still. Red blood stained his collar. A silver dagger pierced him. No one heard his scream. Cold rain lashed the windows. The heavy wooden door creaked. A shadow slid inside quickly. The killer smiled, then vanished.
