D’Artagnan had been there scarcely five minutes when M. de Treville entered.  At the first glance, and by the joy which was painted on his countenance, the worthy captain plainly perceived that something new was on foot.

All the way along d’Artagnan had been consulting with himself whether he should place confidence in M. de Treville, or whether he should only ask him to give him carte blanche for some secret affair.  But M. de Treville had always been so thoroughly his friend, had always been so devoted to the king and queen, and hated the cardinal so cordially, that the young man resolved to tell him everything.

“Did you ask for me, my good friend?” said M. de Treville.

“Yes, monsieur,” said d’Artagnan, lowering his voice, “and you will pardon me, I hope, for having disturbed you when you know the importance of my business.”

“Speak, then, I am all attention.”

“It concerns nothing less”, said d’Artagnan, “than the honor, perhaps the life of the queen.”

“What did you say?” asked M. de Treville, glancing round to see if they were surely alone, and then fixing his questioning look upon d’Artagnan.

“I say, monsieur, that chance has rendered me master of a secret—­”

“Which you will guard, I hope, young man, as your life.”

“But which I must impart to you, monsieur, for you alone can assist me in the mission I have just received from her Majesty.”

“Is this secret your own?”

“No, monsieur; it is her Majesty’s.”

“Are you authorized by her Majesty to communicate it to me?”

“No, monsieur, for, on the contrary, I am desired to preserve the profoundest mystery.”

“Why, then, are you about to betray it to me?”

“Because, as I said, without you I can do nothing; and I am afraid you will refuse me the favor I come to ask if you do not know to what end I ask it.”

“Keep your secret, young man, and tell me what you wish.”

“I wish you to obtain for me, from Monsieur Dessessart, leave of absence for fifteen days.”

“When?”

“This very night.”

“You leave Paris?”

“I am going on a mission.”

“May you tell me whither?”

“To London.”

“Has anyone an interest in preventing your arrival there?”

“The cardinal, I believe, would give the world to prevent my success.”

“And you are going alone?”

“I am going alone.”

“In that case you will not get beyond Bondy.  I tell you so, by the faith of de Treville.”

“How so?”

“You will be assassinated.”

“And I shall die in the performance of my duty.”

“But your mission will not be accomplished.”

“That is true,” replied d’Artagnan.

“Believe me,” continued Treville, “in enterprises of this kind, in order that one may arrive, four must set out.”
