Rain hammered the cracked pavement. Streetlights flickered like dying candles. Silhouette lingered near dark alley. A scream shattered midnight silence. Detective Marlowe arrived, coat soaked. He surveyed the scene, unsettled. Blood pooled beside broken vase. A single glove lay abandoned. Footprints led toward the river. Moonlight reflected off trembling water. Someone whispered, justice will find. The night held its breath.
