September 1940: When the police and the civil authorities suspect that petrol is being stolen from a local depot, Foyle agrees to let Sam Stewart go undercover as a driver to see if she can find out what is going on. Sam is partnered with Connie Dewar who is in love with a flying officer, Rex Talbot who just happens to be Andrew Foyle's best friend. It becomes apparent to Sam that Connie is involved in the petrol thefts and when she is found dead, there are a number of suspects. Connie is also several months pregnant but she didn't tell anyone who the father was. For DCS Foyle, the case becomes especially complicated when it turns out his son Andrew was perhaps the last person to see her alive. Written by garykmcd

Sam Undercover
1 August 2016 | by (United States) – See all my reviews

With the advent of fuel pirating, Foyle allows Sam to begin doing undercover work. Unfortunately, there are some really bad characters, including those who would kill to cover up their actions. She stumbles on documents that would bring about an investigation into out and out treason. It is a little hard to swallow that Sam is doing this work. She also gets caught in the middle of a relationship among several women with whom she works. There is tension, as she must lie frequently to keep her cover. She also unwittingly brings herself into a series of close calls. She does valuable work for Foyle, but he fears for her life every step of the way. The conclusion of this episode is a bit much to believe. But it is fun seeing the young lady going through her paces.
