Cold rain fell heavily upon the dark and empty street. Detective Miller knelt beside the lifeless body lying there. Dark crimson blood pooled slowly underneath the heavy winter coat. A shattered pocket watch ticked softly in the muddy gutter. He checked her icy wrist for any faint human pulse. Nothing remained except the empty silence of the night air. Someone had ended her promising life with extreme brutal force. Miller looked toward the looming shadows of the alleyway.
