Rain fell hard over town. The old house stood silent. Detective Kane arrived after midnight. A woman screamed from upstairs. Blood pooled beneath the window. No one had heard anything. The victim's eyes stared blankly. Kane knelt beside the body. Something metallic glinted near her. This case would haunt him.
