Thunder rattled the manor windows. Detective Mara entered before midnight. Inside, every candle burned blue. Twelve guests awaited their host. His chair remained strangely empty. Then the library bell screamed. Mara counted each startled face. Nobody had touched the cord. Upstairs, a locked door opened. A body toppled downwards, smiling. Around its throat gleamed silver. Mara recognized her missing necklace.
