Vipers' Tangle by Francois Mauriac tells the story of Monsieur Louis, an embittered aging lawyer who keeps a journal—and shares it with his estranged family—in which he records the vipers’ tangle of his own heart and soul. The novel masterfully explores the corruption caused by pride, avarice, and hatred, but then examines the divine grace that remains available to each of us until the very moment of our death.
