A dense fog shrouded the cobblestone streets. Gas lamps flickered, casting eerie shadows. A lone figure strode purposefully ahead. His coat collar was turned up against the chill. He paused at a secluded alleyway. A muffled scream echoed through the mist. He hesitated, then stepped into the darkness. Inside, a lifeless body lay sprawled on the ground. Blood seeped from a wound in the victim's chest. The man knelt, touching the cold, clammy hand. He looked around, spotting a discarded knife nearby. Panic surged, but he fought the urge to flee. Instead, he pulled out his phone and dialed a number. The ringing echoed in the silence of the night. "I need to report a murder," he said grimly.
