Cold sleet whipped violently against the broken parlor window pane. Lord Ashford lay motionless upon the stained white wool rug. A crimson pool spread slowly beneath his cold, pale neck. The grandfather clock chimed midnight with a solemn, heavy ring. Dripping footprints led directly toward the dark oak cellar door. Inspector Vance removed his wet trench coat near the foyer. He found a golden hairpin gleaming in the dim light. No one in this grand mansion possessed a clean alibi. The killer was definitely still hiding somewhere inside this house.
