The fog swallowed Blackthorn Manor. At midnight, the bells stopped. Detective Vale arrived before dawn. Nobody had summoned her there. Yet someone expected her arrival. The front door stood open. Inside, candlelight trembled against portraits. A woman lay beneath them. Her throat bore no wound. Her eyes remained terribly wide. One hand clutched a photograph. The other pointed toward Vale. Vale recognized the dead woman. She had buried her yesterday.
