Sparkling Cyanide

Beautiful Rosemary Barton , wife of wealthy George Barton, dies by poison at a dinner party, and as one of the guests is a government minister who was having an affair with Rosemary, Colonel Geoffrey Reece (Oliver Ford Davies) and his wife Dr Catherine Kendall (Pauline Collins) are called on to solve the mystery. Although some of the characters are very different from the ones in the book, the basic plot remains the same, as does the identity of the murderer. The detectives, Reece and Kendall, have replaced the novel's Colonel Race (contrary to what another reviewer seems to think, Sparkling Cyanide is not a Poirot novel) but I didn't mind that as I found their characters very entertaining, rather reminiscent of the elderly Tommy and Tuppence, especially as their children are, like Tommy and Tuppence's offspring, unaware of the exciting activities of their parents. I would have liked to see them in some more adventures. I suppose it's too late now for a spin off series.
