Henry gets some disturbing news - his business partner Arthur Langham ( Michael Napier Brown ) suspects wife Connie ( Yolande Turner ) of having an affair, and has placed a tape recorder in his flat, hoping to identify her mystery lover.
Said lover is none other than Henry himself. Packing off Arthur on a business trip to Africa, he sets about hunting for the recorder. With Connie's help, the flat is turned upside down. Nothing is found.
Whenever Henry and Connie wish to talk, they have to leave the flat, and in so doing attract the attention of a neighbour ( Donald Morley ). Henry tries to justify his presence by pretending to be a canvassing Tory candidate. When Henry is still there hours later, the neighbour grows suspicious.
Exhausted and in despair, Henry returns to his office for an angry confrontation with Arthur. But the voice on the tape recorder is not the one he expected to hear...
With Watergate very much in the news when this was made, the timing could not have been better. A year after this went out, Francis Ford Coppola made 'The Conversation' in which surveillance expert Gene Hackman destroys an apartment trying to find a tape recorder. Was Coppola a 'Casanova 73' fan? The mind boggles. There is a sub-plot about representatives from an African state threatening to cancel their account with Henry's company as their entrant in an international beauty contest got pregnant - Henry strikes again! - whilst in London but nothing is made of it.
Janet Davies - 'Mrs.Pike' from 'Dad's Army' - is the wife of the Langhams' garrulous neighbour. Great performance by the late Donald Morley. His 'are you planning to set up committee rooms?' as he spots Henry outside Connie's flat late at night is beautifully delivered.
Funniest moment - Henry realising Connie has not only been unfaithful to her husband, but to him too!
