Goodnight Sweetheart - Season 3 (1996)

Gary, Reg and Phoebe attempt to apprehend a Nazi spy.

As Ron's marriage problems hit a new low, an overconfident Gary offers him some seemingly sound advice.

Ron unexpectedly turns up at the Sparrow household with suitcase in hand. Phoebe suggests Gary should assume teaching duties for the local children who haven't been to school in months.

Gary bumps into his former talent agent, Sidney Wix, which leads to an unwelcome collaboration with superstar ukulele player, George Formby.

Phoebe's husband Donald, who has escaped from the prison camp in Italy, returns. Gary feels he must give Phoebe up for good - Ron suggests he tell her he is an alien from the planet Zircon - but both Phoebe and Donald tell Gary separately that they allowed themselves to be pushed into a somewhat passionless marriage by relatives. It is implicit in what Donald tells Gary that his real love was Steve, with whom he planned to emigrate but was killed in North Africa. Donald takes his leave, bidding Gary to take care of Phoebe. Yvonne is devastated because Gary again fails...

When Phoebe is ill with pneumonia Gary brings her penicillin, the bottles belonging to Yvonne and Ron, who had some for his poorly dog Sheba. Phoebe recovers and, seeing the name Sheba on the label, suspects Gary is seeing another woman. He decides to tell her the truth about Yvonne but she has already fallen asleep.

When the Yanks come to the Royal Oak Gary is able to get Ron the parts he needs to build his own jeep and Reg discovers he has a black cousin, in the area to trace his ancestors. A racist corporal called Billy Joe tries to ban the black soldiers from the pub so Gary gets him drunk and knocks him out. Yvonne is so thrilled by the success of the memorabilia shop that Gary is worried by her zeal and takes steps to dampen her enthusiasm.

Gary's parallel lives run parallel as Yvonne puts their house in Cricklewood on the market to move to 'yuppy heaven' with a gym and a pool and Phoebe rents a house in the suburbs from a woman who is moving to Devon for the war's duration. Both women are pregnant by him but, as he tells Ron, Phoebe needs him more, meaning he must spend less time in the present.
