Cold rain lashed against the cracked window of the study. Lord Reginald sat slumped over his mahogany desk, completely still. A single bullet hole punctured his silk waistcoat, bleeding slowly. The grandfather clock chimed midnight with a dull, hollow metallic sound. Inspector Vance stepped inside the room, shaking his heavy coat. He observed the spilled glass of amber whiskey on the rug. No signs of any forced entry appeared on the doors. The killer had entered with a key, or was invited.
