At length, after waiting a quarter of an hour and just as twilight was beginning to thicken, a carriage appeared, coming at a quick pace on the road of Sevres. A presentiment instantly told d’Artagnan that this carriage contained the person who had appointed the rendezvous; the young man was himself astonished to find his heart beat so violently. Almost instantly a female head was put out at the window, with two fingers placed upon her mouth, either to enjoin silence or to send him a kiss. D’Artagnan uttered a slight cry of joy; this woman, or rather this apparition--for the carriage passed with the rapidity of a vision--was Mme. Bonacieux.

By an involuntary movement and in spite of the injunction given, d’Artagnan put his horse into a gallop, and in a few strides overtook the carriage; but the window was hermetically closed, the vision had disappeared.

D’Artagnan then remembered the injunction: "If you value your own life or that of those who love you, remain motionless, and as if you had seen nothing."

He stopped, therefore, trembling not for himself but for the poor woman who had evidently exposed herself to great danger by appointing this rendezvous.

The carriage pursued its way, still going at a great pace, till it dashed into Paris, and disappeared.

D’Artagnan remained fixed to the spot, astounded and not knowing what to think. If it was Mme. Bonacieux and if she was returning to Paris, why this fugitive rendezvous, why this simple exchange of a glance, why this lost kiss? If, on the other side, it was not she--which was still quite possible--for the little light that remained rendered a mistake easy--might it not be the commencement of some plot against him through the allurement of this woman, for whom his love was known?

His three companions joined him. All had plainly seen a woman’s head appear at the window, but none of them, except Athos, knew Mme. Bonacieux. The opinion of Athos was that it was indeed she; but less preoccupied by that pretty face than d’Artagnan, he had fancied he saw a second head, a man’s head, inside the carriage.

"If that be the case," said d’Artagnan, "they are doubtless transporting her from one prison to another. But what can they intend to do with the poor creature, and how shall I ever meet her again?"

"Friend," said Athos, gravely, "remember that it is the dead alone with whom we are not likely to meet again on this earth. You know something of that, as well as I do, I think. Now, if your mistress is not dead, if it is she we have just seen, you will meet with her again some day or other. And perhaps, my God!" added he, with that misanthropic tone which was peculiar to him, "perhaps sooner than you wish."

Half past seven had sounded. The carriage had been twenty minutes behind the time appointed. D’Artagnan’s friends reminded him that he had a visit to pay, but at the same time bade him observe that there was yet time to retract.

But d’Artagnan was at the same time impetuous and curious. He had made up his mind that he would go to the Palais-Cardinal, and that he would learn what his Eminence had to say to him. Nothing could turn him from his purpose.
