At midnight, rain erased every footprint outside the old theater. Detective Mara Voss found one umbrella beneath the locked balcony. Its silver handle bore initials belonging to the missing mayor. Inside, the stage curtains stirred though every window remained sealed. A single spotlight illuminated the victim’s empty, bloodstained chair. From backstage, someone whispered Mara’s name, then laughed softly. She drew her pistol and stepped toward the darkness alone.
