James Carpenter is a successful doctor at the peak of his career and is also an orchid fanatic, much more devoted to his flowers than he is to his elegant wife, Hermione. And Carpenter is also in love with a younger woman, Samantha. Then a research posting to the U.S. gives the doctor the idea for the perfect murder... Alas for Carpenter and his mistress, the victim has a trick up her sleeve, even from the grave...
