Cold rain fell steadily upon the dark and empty street. Detective Miller knelt beside the lifeless body lying there. Dark crimson blood pooled slowly beneath the broken open skull. A shattered pocket watch rested near the stiff pale hand. Midnight had passed hours ago in this forgotten quiet neighborhood. No witnesses remained to tell the grim and sudden story. He sighed deeply and prepared for a long difficult investigation.
