Detective Miller arrived at the crime scene just after midnight, the rain lashing against his trench coat as he surveyed the dimly lit alley. The victim lay motionless near the dumpster, blood pooling on the wet pavement while nearby officers secured the perimeter. Miller knelt carefully beside the body, noting the victim's contorted expression and the single stab wound to the chest. The rain had washed away most footprints, but Miller spotted a distinctive heel print near the victim's right hand. His phone buzzed with an urgent message: the victim was a prominent businessman with many enemies and few friends. Miller's eyes caught something glinting in the victim's pocket - a small silver locket with a broken chain. The forensic team arrived, their flashlights cutting through the darkness as they began their meticulous search for clues. Miller noticed a discarded cigarette butt near the trash can, brand unfamiliar but expensive, perhaps a clue. As the first morning light began to creep in, Miller realized this murder was far more complicated than he initially thought. The victim's phone rang suddenly, startling everyone at the scene - the caller ID showing an unknown number.
