After meeting Burnside and the rest of SIS in Series 1 of The Sandbaggers, we had just about got to grips with the many acronyms of Whitehall and were soon ready to delve into Series 2.
I rejoined Spybrary host Shane Whaley and fellow fans Jeffrey Westhoff and Peter Newman to discuss more on The Sandbaggers.
If you fancy exploring more from the top secret Spybrary files, you can find more episodes on the Spybrary website.
The podcast has an active Facebook group and is a really welcoming community for both new and veteran espionage fans.
