Jean Valjean advanced, carefully avoiding the furniture. At the far end of the room he could hear the even, quiet breathing of the sleeping bishop.

He was almost completely dressed in bed, because of the cold Basse-Alpes nights. His head was tilted back on the pillow in the unstudied attitude of sleep. His face was lit up with a vague expression of a contentment, hope, and happiness. It was almost a radiance, a luminous transparency, for this heaven was within him: it was his conscience.

Jean Valjean stood in the shadow, erect, motionless, terrified. He had never seen anything like it. The moral world has no spectacle more powerful than this: a troubled, restless conscience on the verge of committing a crime, contemplating the sleep of a just man.

--Victor Hugo, Les Miserables
