The body lay crumpled beneath the old oak tree outside. Detective Morgan arrived at the scene just after midnight struck. Rain had washed away most of the evidence by then. A single red scarf was wrapped tightly around her neck. No one had reported the young woman as missing yet. Her eyes stared upward at nothing, frozen wide with terror. Morgan knelt down and studied the bruises on her wrists. This was no robbery and no random act of violence. Someone had taken great care arranging the body like this. Her hands were folded neatly across her chest, almost peaceful. A folded note protruded from the pocket of her coat. Morgan pulled on gloves before carefully retrieving the damp paper. Three words were scrawled in ink that had barely smudged. The message was simple and cold: she deserved this fate. Morgan stood slowly and scanned the dark tree line ahead. Somewhere out there, a killer was watching and feeling proud.
