“Mais à peine se vit-il en chemin qu’une pensée terrible l’assaillit, et telle, que peu s’en fallut qu’elle ne lui fît abandonner l’entreprise commencée.” — But scarcely did he see himself on the road when a terrible thought assaulted him, and such that little was missing to make him abandon the enterprise he had started.
