The entire comedy drama series from Alan Plater. In 'The Beiderbecke Affair' (1984), woodwork teacher and jazz buff Trevor Chaplin (James Bolam) has always fantasized that a beautiful blonde will enter his life and simultaneously provide him with rare recordings of his hero Bix Beiderbecke. Unlikely as it seems, this is just what happens one evening when Trevor is at home in his flat. It is an encounter which will ultimately involve him and his colleague, independent political campaigner Jill Swinburne (Barbara Flynn), in exploding lawnmowers, political corruption and the strange world of 'black economists' Big Al (Terence Rigby) and Little Norm (Danny Schiller). In 'The Beiderbecke Tapes' (1987) Trevor and Jill find themselves plunged into another jazz-related mystery when the former purchases some Bix Beiderbecke tapes from a pub barman. Jill is intrigued when one of the tapes contains a conversation about the planned dumping of nuclear waste in the Yorkshire Dales, her curiosity being roused still further by the discovery that the barman who sold Trevor the tapes has now gone missing... The intrepid duo soon find themselves up to their necks in trouble once more as their investigation takes them from the relative safety of Yorkshire to the mean streets of Amsterdam and Edinburgh. In the final part of the trilogy, 'The Beiderbecke Connection' (1988), Trevor and Jill are still living together, and they now have a baby boy to look after as well. Their household is increased still further when old friend Big Al asks them to take in a refugee as a favour; Trevor is reluctant until he discovers that his new guest is, like him, an ardent jazz fan. However, this visitor is only the first of many who will involve Trevor and Jill in yet more intrigue and deception.
