The Vicomte de Bragelonne by Alexandre Dumas

After the austere lesson administered to De Wardes, Athos and D'Artagnan together descended the staircase which led to the courtyard of the Palais-Royal. "You perceive," said Athos to D'Artagnan, "that Raoul cannot, sooner or later, avoid a duel with De Wardes, for De Wardes is as brave as he is vicious and wicked."

"I know such fellows well," replied D'Artagnan; "I had an affair with the father. I assure you that, although at that time I had good muscles and a sort of brute courage-I assure you that the father did me some mischief. But you should have seen how I fought it out with him. Ah, Athos, such encounters never take place in these times! I had a hand which could never remain at rest, a hand like quicksilver,-you knew its quality, for you have seen me at work. My sword was no longer a piece of steel; it was a serpent that assumed every form and every length, seeking where it might thrust its head; in other words, where it might fix its bite. I advanced half a dozen paces, then three, and then, body to body, I pressed my antagonist closely, then I darted back again ten paces. No human power could resist that ferocious ardor.
