An American airman has written a magazine article about his experiences being shot down in Europe and getting back home with the help of the evasion lines. British Intelligence has blocked the article’s publication, but Brandt has managed to obtain a copy from German intelligence based in America. Studying the article, he begins to deduce the probable route taken during the evasion and travels to the Pyrenees, where he enlists the aid of Malaud, a French policeman, to close in on the line. Meanwhile, Lisa is also in the area, taking some evaders down the very route Brandt is so close to tracking down.

With so many evaders, Lifeline’s resources are once more stretched to the limit and they must watch their backs after recent events. Jacques and Natalie are dispatched to check out a young South African evader, Noel Uys, and have to consider eliminating him when his answers to their questions fail to satisfy either them or London. In desperation to survive, Uys overpowers Jacques and armed with a shotgun, takes Natalie as his hostage.

Curtis’ cover has been blown and Kessler knows that he is part of the resistance. To avoid endangering the others, Curtis goes to ground in Brussels. Knowing that Lifeline is at last in his sights, Kessler orders that all routes out of the city are blocked and co-ordinates a house-to-house search throughout the city. In desperation, Curtis goes to the Candide to ask for help, and Monique comes up with a highly audacious escape plan.
