“Listen to me, youngster,” he said. “It’s not a question of picking one’s words. It’s a question of a fact, a positive, indisputable fact; and that fact is this: in all the past ten years, I have not yet knocked up against an adversary of your capacity. With Ganimard and Holmlock Shears I played as if they were children. With you, I am obliged to defend myself, I will say more, to retreat.

“Are you sure that I know it?”
