Rain hammered the greenhouse glass. Detective Nora Vance arrived late. The body lay among orchids. Someone had arranged him carefully. His folded hands held lilies. Funeral flowers, Nora thought grimly. The gardener wept near steps. Nobody else had touched anything. She doubted that claim immediately. Mud tracked across pale tiles. Two sets of prints, actually. One belonged to the victim. The other wore smaller shoes. Thunder rolled above the roof. Nora crouched beside the corpse. No wound was immediately visible. His parted lips looked blue. Poison, then, she decided quietly. Behind her, the door clicked. Someone had locked them inside.
