Rain tapped the dark window. A clock ticked too loudly. Detective Mara Bell stood still. The manor smelled of smoke. Lord Ashby missed his dinner. His chair sat empty downstairs. Mara checked the locked study. A silver knife lay shining. Blood stained the pale rug. No footprints crossed the floor. The window was shut tight. A clock chimed one time. Someone knocked at the door. Mara turned toward the sound. The butler entered with tea. His hands trembled very slightly. "Where is Lord Ashby now?" Mara picked up the knife.
