The far-right leagues of the 30s, Vichy, the collaboration with Germany, the purification, the Cold War, the events of Algeria, the African oil ... Philippe Richelle revisits the History of France for years 30 in our day in a great detective series carried by three talented designers: Pierre Wachs, Alfio Buscaglia and François Ravard. In three cycles of independent stories, police investigating crimes will enter the obscure meanders of the great history, sometimes showing it in its most ignored aspects. Scenario: Richelle, Philippe. Drawing: Wachs, Pierre.
