Within an Inch of His Life by Emile Gaboriau

Like all very clever men, Dr. Seignebos made the mistake of thinking other people as cunning as he was himself. M. Galpin was, of course, watching him, but by no means with the energy which one would have expected from so ambitious a man. He had, of course, been the first to be notified that the case was to be tried in open court, and from that moment he felt relieved of all anxiety.

As to remorse, he had none. He did not even regret any thing. He did not think of it, that the prisoner who was thus to be tried had once been his friend, -- a friend of whom he was proud, whose hospitality he had enjoyed, and whose favor he had eagerly sought in his matrimonial aspirations. No. He only saw one thing, -- that he had engaged in a dangerous affair, on which his whole future was depending, and that he was going to win triumphantly.
