Rain slicked the alley as the clock struck midnight sharply. A shadow lingered near the door, watching for unwary footsteps. Inside, a lamp flickered, casting pale echoes across polished surfaces. The victim lay unmoved, a note clenched within stiff fingers. Detective Mara approached quietly, cataloging clues with practiced, deliberate patience. The note hinted at betrayal, yet offered no clear motive. Outside, rain intensified; distant thunder forced the city to listen. Somewhere, a piano sighed, as secrets tucked themselves beneath shadows.
