The rain fell hard on the cobblestone streets of London. Detective Inspector Graves pulled his trench coat collar up tight. A constable stood shivering outside the old theater's stage door. Inside, the famous actress lay crumpled on the cold floor. Her emerald necklace was missing, but no blood was visible. Graves carefully knelt down, studying the victim's frozen lifeless expression. A single red rose was clutched in her stiff hand. He noticed a torn theater ticket stub under her shoe. The room smelled of perfume, dust, and something metallic underneath. This was no simple robbery; the killer had been precise.
