Rain hammered Blackwood House while the whole village slept below. At dawn the butler found the library door wide open. Inside Sir Adrian Vale lay cold beside his oak desk. A silver letter opener rested beside his curled right hand. The tall window stood open though the storm had passed. Wet mud darkened the carpet yet no footprints remained visible. Every clock in the house had stopped at twelve sharp. By breakfast Inspector Mara Crowe arrived with one question already.
