Rain hammered the greenhouse glass. Inspector Vale hated wet mornings. The body lay among orchids. Someone had arranged her hands. Palms up, fingers gently curved. One petal covered her mouth. No blood stained the soil. Vale crouched, studying the wound. Something thin had pierced her. Her name was Margaret Ashcombe. She owned this entire estate. By tomorrow, everyone would know. The gardener waited outside, trembling. The door was locked, apparently. Vale checked it himself twice. Only one key existed here. It hung around her neck. Rain kept hammering the glass. Vale stood and surveyed everything. Wet footprints crossed the floor. They ended in the middle. Nothing about this made sense. Somebody had wanted her found. That was the whole point.
