Another exceptional episode of "Thriller" - one of the best.
Roger Masters (Michael Jayston) is a butler employed by widow Laura Vallance (Nyree Dawn Porter). Unknown to her he has already poisoned his last employer. Immediately he is at odds with the existing maid Betty (Clare Sutcliffe) so he frames her for a theft to get her fired, then brings in his girlfriend Lisa (Janet Key) as her more accommodating replacement. The pair slowly poison Laura, aided by a disgraced doctor (Thorley Walters).
Over time Laura becomes sicker and suspicious as Masters cuts her off from outside contact, particularly with her American friend Hugo (Barry Nelson). He also becomes worried by Masters's refusal to let him see her. Masters starts to realise that he is under pressure and the stage is set for some very fateful decisions...
This riveting story was written by the excellent Terence Feely. The direction by Robert D. Cardona is first class and creates a very tense ambience. The climax is superb. The script also features some very witty dialogue.
There are many fine acting displays. Jayston is marvellous as the spiteful Masters. Behind his terribly correct exterior Masters is aggressive and bullying. Jayston pulls this image off with ease. His nastiness is irresistible to watch. Especially powerful are the scenes with the disgraced doctor, very capably played by Thorley Walters, in which Masters's resentment at his humble origins explodes in the presence of the shambling, alcoholic doctor who has squandered his privileged upbringing. Nyree Dawn Porter is, as always, accomplished as the hapless Laura, and generates real affection for her character. Sadly she virtually disappeared from the screens after this. In the supporting roles there are strong displays by Janet Key, Clare Sutcliffe, and Victor Winding as a very sharp detective.
Definitely an episode to check out - you will not be disappointed!
