The cold rain fell hard against the old manor windows. Detective Hale stepped inside, shaking cold water from his coat. A young woman's body lay motionless beside the stone fireplace. Her wide eyes stared upward, frozen forever in silent fear. No weapon lay near her, only silence and deep shadows. Hale knelt down slowly, studying the room for hidden clues. Something about this whole crime scene felt deliberately staged tonight. He knew this strange case would haunt him for years.
