Secret Army is a British television drama made by the BBC and the Belgian national broadcaster BRT (now VRT) created by Gerard Glaister.

It tells the story of a fictional Belgian resistance movement in German-occupied Belgium during the Second World War, an escape line dedicated to returning Allied airmen, usually shot down by the Luftwaffe, to Great Britain.

Their operations are placed under strain when the fervent Nazi, Gestapo Sturmbannführer Ludwig Kessler is assigned to work with Luftwaffe Major Erwin Brandt and close down the evasion line.

Flight Lieutenant John Curtis, a former evader, is sent back by London as a Special Operations Executive liaison officer to coordinate its activity.

The series highlights the risks that the main characters take to rescue the young airmen whilst under German occupation, protecting their safe houses, and evading investigation.

Kessler orders a troop encirclement of Brussels, but Curtis manages to escape to Switzerland by posing as bus driver for a local Hitler Youth group that is travelling out of the city on a day trip.

This venture is 60% clandestinely owned and financed by London, so as to enable the members of Lifeline to cater for senior German officers, allowing them to overhear indiscretions and to provide better cover for their activities.

Secondary storylines include Kessler's developing romance with lonely Belgian 'society woman' Madeleine Duclos, whom he meets while dining alone at Le Candide, and Brandt being asked to join a conspiracy to assassinate Hitler.

As news of the Allied troops' imminent arrival reaches the streets, the Germans find it increasingly difficult to keep order and eventually they leave the Belgians to their own devices.

Reinhardt is a cynical and world-weary war hero (he has been awarded the Knight's Cross), whose unorthodox approach is at odds with Kessler's by-the-book methods.

In Albert's absence, Lifeline is helped by Major Nicholas "Nick" Bradley, a charismatic British agent who previously appeared during the second series.

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.

Albert is hanged after a Communist-run 'kangaroo court' finds him guilty of treachery for his part in the death of Max Brocard; just in time, he is cut down and saved by British troops.

The character of John Curtis was influenced by the experiences of the series's technical consultant, Group Captain William Randle, who escaped from occupied Europe in 1942 and was later Keeper of the Battle of Britain Museum.

The End of the Line covers several series three episodes, principally Revenge, Ring of Rosies, Just Light the Blue Touch Paper, Collaborator, Bridgehead and The Execution.

This features reviews of every episode, information on the real-life events that inspired the series, behind-the-scenes production material, a location guide, and reminiscences and photos from cast and crew.

This also carries interviews with cast members Angela Richards, Clifford Rose, Juliet Hammond-Hill, Terrence Hardiman and Hazel McBride.

The songs performed by Angela Richards and pianist Ken Moule proved so popular with audiences that a BBC soundtrack album entitled Au Café Candide was released.

Tracks include Richards's own compositions "Memories Come Gently" and "If This Is The Last Time I See You", together with popular Forties numbers such as "Lilli Marlene" and "J'attendrai".
