Rain hammered the greenhouse glass. Inspector Vale arrived past midnight. The orchids were still blooming. Beneath them lay Gregory Ashworth. His hands clutched pruning shears. Blood darkened the white gravel. Someone had arranged him carefully. The pose seemed almost devotional. Vale crouched, studying his face. No fear lingered there whatsoever. Only mild, unremarkable surprise remained. He had known his killer. The greenhouse door was locked. From the inside, Vale noted. Behind her, the housekeeper wept. Six guests waited inside, listening. One of them was lying.
