Rain slicked the grimy cobblestones of the alley. A lone figure lay huddled and still. His bowler hat had rolled into a puddle. Detective Miller surveyed the disturbing, gruesome scene quickly. The watch on his wrist read midnight. Blood pooled darkly spreading under the victim. A glinting dagger lay beside him oddly. Miller sighed and slowly knelt to examine. This would be a long, miserable night. The chill wind carried a haunting whisper.
