The fog clung low over the cobblestone streets at midnight. A lone figure hurried past shuttered shops with quick strides. Their breath came in sharp bursts, visible in the cold air. Behind them, shadows flickered in the dim glow of streetlamps. Something metallic gleamed faintly near the alley’s overflowing trash bin. The figure paused, sensing movement where there should be none. A gloved hand reached down to pick up the object. It was a pocket watch, its face cracked but ticking. Before they could react, a scream pierced the silent night. The figure dropped the watch and ran toward the sound.
