The grand marble clock struck midnight with a slow, deliberate chime throughout the dark, silent mansion. Detective John Hale stepped across the threshold into the cavernous, shadow-filled foyer, his expression grim. One single, powerful beam from his heavy flashlight cut through the oppressive, dusty gloom ahead. It illuminated a terrible scene: Lord Ashworth’s body lay sprawled upon the Persian rug. A silver dagger, ornate and cruel, protruded from his motionless, starched white shirtfront quite obviously. There would be no peaceful sleep for anyone within these old, cold walls tonight.
