Rain fell softly over town. The old house stood silent. Detective Cole arrived after midnight. A scream broke the silence. Neighbors peered through their curtains. Blue lights flashed against windows. Inside, a body lay motionless. Blood pooled beneath the desk. Cole knelt beside the victim. Something felt deeply, terribly wrong. The killer was still nearby.
