Here is a teaser from Death in the Orchid Garden by Ann Ripley:
"Around her arose an imported jungle of palms and lacy casuarina trees, Norfolk pines as tall as a five-story building, giant armed monkeypods, blazing philosophy trees, and snakelike cactus growing on random walls. Ringing the lagoon itself were splotches of croton, ginger, plumeria, guava, ficus, and hibiscus...It was her business, since she was host of the PBS garden show, Gardening With Nature, in Washington, D. C."
