Rain polished the manor windows. Inside, someone had stopped breathing. Detective Mara Vale arrived alone. The front door stood ajar. Every clock showed eleven seventeen. Except one, which ticked backward. Lord Bellamy lay beneath portraits. His mouth held one key. His hands were perfectly clean. The carpet beneath him wasn't. Blood spelled Mara beside him. She had never met Bellamy. Then the telephone rang upstairs. She lifted the dusty receiver. A voice whispered, “You're late.” It sounded exactly like Bellamy.
