Auzou Book for expedition: the Atlantic

March 1941. Stuck in bombed-out London, Papi and Lucien are called to a new mission. General de Gaulle lui-même invites them to join him in Brazzaville, at Congo, where the capital of the Free France has been established. There was no question, however, of returning via France, which had been invaded by the Nazis. Papi and Lucien embark on a cargo supply ship, bound for Africa. But Helmut, the Nazi soldier who is as relentless as he is stupid, has also come on board, with a single aim: to take revenge on Papi and Lucien.
