Pristine potion in which an eccentric botanist gets the find of his career with the seeds of a sacred Andean plant, and disappears after their receipt. Suspected-mildly -- of his unproven murder are his foster-daughter, her fiance, and Nicholas, a writer. The plant in blossoming points the way to the corpse and the killer. Intended as a Lorror story, this doesn't scare up much -- not even a heebiejeebie.
