Rain hammered the greenhouse glass. Inspector Vale hated wet mornings. The body lay facedown there. Someone had arranged her hands. Palms up, like an offering. Orchids bloomed above the corpse. Their white petals looked scrubbed. No mud, no prints, nothing. Sergeant Okafor crouched beside him. She pointed at the neck. A thin bruise ringed it. Garden wire, Vale said quietly. The victim was Margaret Crowe. She owned this entire estate. Six guests had slept upstairs. None of them heard anything. Vale doubted that very much. Rain kept hammering the glass. The orchids smelled like funerals. Someone here loved arranging things.
