Rain hammered the glass while Inspector Vale entered the library. A candle burned beside Sir Julian, pale and quite dead. His right hand clutched a ticket for the midnight train. Across the room, Lady March smiled without showing her eyes. The clock stopped at eleven, though its pendulum still swayed. Outside, thunder hid the scrape of a key turning twice. Vale noticed ink on the cuff, fresh as new blood.
