In Albert's absence, Lifeline is helped by Major Nicholas "Nick" Bradley, a charismatic British agent who previously appeared during the second series. Monique resents his presence, believing he threatens her new authority, whereas Natalie has been attracted to Bradley since his earlier visit. Bradley's job is to make sure the remaining evaders are fed and armed to protect themselves whilst they hide in the Ardennes. During his time in Belgium, Bradley succeeds in saving Alain from torture by the Gestapo, blows up a convoy, destroys a V-2 site and discovers where the Germans have laid explosives in the city. Bradley is later shot dead the day before the German withdrawal, being found in the streets after curfew.
