The grandfather clock struck midnight. Rain lashed the dark windows. Lord Blackwood poured his wine. A strange shadow crossed outside. Sudden footsteps echoed nearby halls. Heavy wooden doors burst open. The study lights flickered out. A sharp blade gleamed silently. Crimson blood stained cold marble. The crystal glass shattered loudly. Nobody heard his dying gasp. A gloved hand stole everything. Footsteps faded into deep darkness. The wealthy master was dead.
