The grandfather clock stopped thirteen minutes before they discovered Eleanor. Outside, rain worried the windows like fingers seeking an invitation. I arrived carrying flowers, which suddenly seemed an unforgivable extravagance. The butler took my coat without looking at my face. His gloves were immaculate, except for one darkened little finger. Eleanor lay beneath her portrait, wearing somebody else's pearl necklace. Her own pearls scattered across the carpet, bright as teeth. Nobody mentioned the knife protruding neatly between her narrow shoulders. They watched me instead, six relatives arranged around untouched champagne. Apparently, my invitation had arrived considerably later than everyone else's. Inspector Vale stood beside the fireplace, studying its cold ashes. He asked whether Eleanor had written anything unusual to me. I felt her letter pressing against my damp breast pocket. Behind him, her grieving husband smiled with terrible, unmistakable relief. Eleanor's final message had warned me not to trust him.
