The rain began at midnight. It hammered against dirty glass. Detective Evans hated the rain. A call came in then. The phone shattered the thick silence. He lifted the worn black receiver. The voice was a whisper. "There is a body here." The line suddenly went dead. The address was old, abandoned. He drove through flooded streets. His headlights cut the dark. The house was deeply still. Its front door hung open. A single light burned upstairs. He stepped onto creaking wood. The smell was sickly sweet. A red scarf lay crumpled. It was not a woman's. A man was slumped forward. A single wound marked him. His hand gripped a photograph. A woman’s face was scratched.
