The rain hammered hard against the tall black library windows. Inspector Vale arrived too late to save the old curator. A silver letter opener protruded from his purple velvet waistcoat. Nobody heard screaming though the storm swallowed every midnight sound. Three guests remained downstairs pretending calm beneath the crystal chandeliers. Vale noticed mud leading inward from the locked garden door. Somewhere upstairs a brass clock began striking thirteen without mercy.
