The south of France is a land of religious and political passions. Anger here fades quickly, but hatred lasts a long time. After the fall of Napoleon, Catholics began to mistreat Protestants, who were protected by the empire. The troubled situation led to the emergence of organizations that called themselves dispensers of justice, but often acted like criminals. Among these is the Brotherhood of Black Sinners. Covering their faces with black hoods in the manner of an ancient monastic order that prayed for the souls of penitent sinners, the newly-minted champions of justice sowed fear and confusion in the hearts of the inhabitants of Provence. What are their real goals, who is their leader - there were many rumors and suspicions on this subject, but there was no exact answer. The next volume of "Masters of Adventure" includes Ponson du Terrail's novel "Captain of the Black Sinners." Using real facts, the writer, whose childhood was spent not far from the places described, sets out his version of the events that agitated the whole of Provence during the reign of King Louis-Philippe I.
