Rain battered the abandoned manor. Detective Mara arrived after midnight. Someone had telephoned her twice. Neither caller had sounded alive. The front door stood open. Inside, thirteen clocks ticked backward. A woman waited beside them. Her black gloves dripped blood. “You’re late,” she whispered softly. Mara glanced toward the staircase. A body blocked its landing. The dead man wore pearls. His mouth held Mara’s photograph. She recognized the picture immediately. It hadn’t been taken yet. Behind her, the door locked. Upstairs, a second woman screamed.
