and in series eight are expecting their first child. Her capabilities develop during the series. At the start, she is a competent driver anxious to help where she can (with surprise interjections from her auto-mechanic and emergency medical training in the Mechanised Transport Corps). She picks up investigative techniques from Foyle and Milner over the years, with occasional mistakes in applying them (e.g. Series 7: Sunflower). However, by Series 8 (High Castle) Foyle is happy to leave her as lead in an interrogation and MI5 is OK with her going undercover for them. Andrew Foyle Squadron Leader Andrew Foyle DFC, RAFVR is Christopher Foyle's only child. At the outbreak of the war he was a student, and joined the RAF in "The German Woman". After undergoing training as a fighter pilot in Scotland, he is posted to the south coast and is involved in radar trials ("Eagle Day"). He sees action in the Battle of Britain. In "Enemy Fire", experiencing combat fatigue stemming from near-constant flying and grief at the loss of many friends, he briefly goes AWOL. His superior, Wing Commander Turner (Martin Turner), is understanding and transfers him to a training unit. Andrew has a girlfriend in "Among the Few", but the relationship does not last. He becomes involved with Stewart until he is posted to Debden as a training officer in "Enemy Fire" (his penultimate on-screen appearance). Soon after his posting, he ends his relationship with Stewart by letter (read in voice-over in "Invasion") after beginning a short-lived relationship with another woman. Promoted to squadron leader and posted to Malta on active service, he is demobilised and sent home after a serious bout of sinusitis ruins his eyesight. He is then an unseen character, referred to only in dialogue and props, until his return to Hastings during the intended last episode ("All Clear"). Apologising to Stewart for his poor treatment of her, he tries to resume their relationship as "friends". Although she seems to be thawing towards him by the end of the episode, in the following series he is replaced as her love interest by Adam Wainwright. Andrew is mentioned as living in London during the seventh series, but is not mentioned when his father visits London and leaves for America. In the eighth series, he is working in the City.
