“The Secret of the Frontenac Family” is Mauriac’s softest and most lyrical novel, in which literary scholars find autobiographical motives. A very unusual family story for France at the beginning of the 20th century. The principles of mutual love, understanding and respect prevail in the family. It is from this that a talented young writer comes out, who has no doubt about his calling. Life will not always be kind to him, but the family values learned in childhood will help him cope with the difficulties, disappointments and defeats of adulthood.
