The grandfather clock struck midnight. Heavy rain lashed the glass. Lord Blackwood poured red wine. A sharp scream shattered silence. His crystal goblet crashed down. Footsteps echoed down the hall. The heavy door creaked open. A masked figure stepped inside. Gleaming steel caught the moonlight. Lord Blackwood gasped for breath. Fresh blood stained the carpet. Another murder shook the estate.
