The body lay motionless on the cold, hard ground. Blood pooled around the victim's head, a gruesome sight. Detective Johnson arrived at the scene, his mind already racing. He knelt beside the corpse, examining the wounds. The killer had used a blunt object, he deduced. The victim's face was unrecognizable, making identification difficult. Johnson searched the area for clues or witnesses. He found a scrap of paper nearby, a cryptic message scrawled in haste. As he pondered its meaning, his partner approached. "We've got a real mystery on our hands," she said gravely.
