The list of famous actors and actresses is impressive, John Glover, Bernard Fox, Len Cariou, Eric Braedon, and Jenny Agutter. Len Cariou episodes are always enjoyable; he is so dashing and suave. He also has a strong romantic interest in Jessica.
The plot, like all episodes, has an interesting twist at the end. The only problem, which is common as to be hackneyed, is ability of a dying man to have the presence of mind to grab a white rose, which surprise, surprise are the flowers growing in the garden, to identify his killer. This silly and implausible vehicle is used in far too many murder mysteries. We are expected to believe that a man who dies in a few seconds is able think clearly enough to spot the white roses and realize he can leave cryptic clue about his killer by grabbing one.
That complaint aside, this is an excellent episode, I recommend it.
