Rain fell on Ashford Manor. Inspector Harold Briggs arrived late. The corpse lay beneath it. Nobody had touched anything yet. Blood pooled across marble floors. A shattered glass lay nearby. Lady Eleanor Ashford died tonight. Her husband waited by hearth. His hands trembled without pause. Someone in this house lied. Briggs noticed one missing necklace. Its clasp had been cut. The murderer was still inside.
