Murray Matheson plays Thomas Edward Griffith, a 19th century man and skilled poisoner who has just gotten married to his beautiful wife Frances(played by Sarah Marshall) He has just offered her a toast after presenting her portrait, when his "perfect" world is shattered by the unexpected arrival of her abrasive mother, and sickly, wheelchair-bound sister who have come to live with them. Frances apologizes for not mentioning their existence, but the in-laws only care about his money, though all are in for a collective financial disappointment, and Thomas realizes that he will have to put his skills to use to remedy this situation... Matheson is superb as the poisoner, charming but ruthless, and episode is richly scored and atmospheric.
