Well, be assured," added he, with the familiarity of a Gascon, "you shall not wait long." And he bowed in order to retire, and as if he considered the future in his own hands.
"But wait a minute," said M.de Treville, stopping him.

"I promised you a letter for the director of the Academy.

Are you too proud to accept it, young gentleman ?" "No, sir," said d'Artagnan; "and I will guard it so carefully that I will be sworn it shall arrive at its address, and woe be to him who shall attempt to take it from me!" M.de Treville smiled at this flourish; and leaving his young man compatriot in the embrasure of the window, where they had talked together, he seated himself at a table in order to write the promised letter of recommendation.

While he was doing this, d'Artagnan, having no better employment, amused himself with beating a march upon the window and with looking at the Musketeers, who went away, one after another, following them with his eyes until they disappeared.
M.de Treville, after having written the letter, sealed it, and rising, approached the young man in order to give it to him.

But at the very moment when d'Artagnan stretched out his hand to receive it, M.de Treville was highly astonished to see his protege make a sudden spring, become crimson with passion, and rush from the cabinet crying, "S'blood, he shall not escape me this time!" "And who ?" asked M.de Treville.
"He, my thief!" replied d'Artagnan.
