Rain lashed against dark glass. The grandfather clock struck midnight. A sudden scream pierced silence. Lord Harrington lay completely still. Fresh blood soaked expensive silk. A silver dagger protruded deeply. His cold eyes stared upward. Footsteps echoed down the hall. The study door slowly opened. Detective Vance entered the darkness. He examined the gruesome scene. The killer remained inside tonight.
