Freezing rain lashed against the tall windows of Blackwood Manor. The grandfather clock in the dark hall struck midnight slowly. A piercing scream shattered the heavy silence within the library. Inspector Vance dropped his warm tea and ran upstairs quickly. He kicked open the heavy oak door with sudden force. Lord Harrington lay motionless across the expensive Persian velvet rug. A silver dagger protruded deeply from his stiff woolen coat. Fresh crimson blood soaked into the delicate patterns below him. The terrace door swung wide open in the chilling gale. A single black glove rested beside the shattered wine glass. The cunning killer had vanished into the stormy midnight shadows.
