When a lock keeper is killed and Jacques is injured, Natalie's fate looks uncertain as she is taken hostage by an impetuous evader whose identity is in doubt... AJ and Andy critique 'the one with the mud' and find a lot more to discuss and explore than this episode's memorable denouement. There is high praise for Juliet Hammond-Hill's performance as Natalie as the character takes centre-stage for the first time, and appreciation of the sequence in which Monique is attacked as a collaborator in the Candide, a troubling rehearsal of events later in the series.  The episode's protagonist, young South African airmen Noel Uys, played by Christopher Douglas, also comes under the spotlight. In a special episode, in two week's time, you will be able to hear AJ's exclusive interview with Christopher to find out what he remembers about his time on Secret Army. As well as focusing on Viktors Ritelis's direction and Raymond London's design, the episode's distinctive soundscape is discussed. And thanks to one of our wonderful listeners we can also reveal the episode's principal windmill and mudflats locations, so you too can lose your shoes and roll around waist-deep in mud should the fancy take you.  Thank you for your continued support of Down the Line and don't forget that we'd love to hear your thoughts on each episode either on Twitter (@secretarmypod) or email ([email protected]), or as a voice-note, also by email (ee will be recording our episode about 'Bait' next if you want to contribute). Edmund Pegge's excellent autobiography, referenced in this episode, is called Forever Horatio and is available on Amazon. Next Time (20 April): Interview with Christopher Douglas (Noel Uys)
