Rain polished the windows as midnight silenced Blackthorn Manor. Detective Mara Voss arrived before servants barred the doors. Inside, Lord Blackthorn waited beneath a shattered chandelier, dead. His clenched hand concealed a crimson feather and key. Nine guests watched Mara, each wearing identical crimson masks. “Count everyone,” Mara ordered, studying their spotless evening shoes. The butler counted twice, then whispered, “We have ten.” From upstairs, a woman screamed, then abruptly began laughing. Mara checked the corpse and found warm wax beneath. “Lock every window,” she said. “Our murderer has vanished.”
