Rain hammered the windows of Blackwood Manor the night Lord Edmund Harrow was found dead in his locked oak study. Inspector Mara Quill arrived at midnight, her umbrella broken, her patience thinner than the fog curling across the gravel drive. The butler, pale and trembling, led her through the great hall where portraits of dead Harrows watched her every step. Nobody had touched the study door, he insisted, until the family broke it down together just before eleven o'clock tonight. Inside, Lord Harrow slumped across his desk, one hand still clutching a silver letter opener buried deep beneath his ribs. Mara knelt beside the body and noticed that the window was latched from the inside, exactly like the heavy door. Somebody in this house had killed a man inside a sealed room, and she fully intended to learn precisely who. Behind her, the grandfather clock struck twelve, and somewhere upstairs a woman began to scream, high and long and terrible.
