Rain fell hard on Elmwood. Detective Grace stood by door. A body lay near fireplace. Blood pooled dark on rug. No one heard the scream. Grace knelt beside the victim. His eyes stared into nothing. She noticed a torn letter. The killer left no fingerprints. Grace sighed, then lit cigarette. This case would haunt her. Somewhere, the real killer smiled.
