"Now he is gone, it is your turn to get out," said Mme. Bonacieux. "Courage, my friend, but above all, prudence, and think what you owe to the queen."

"To her and to you!" cried d'Artagnan. "Be satisfied, beautiful Constance. I shall become worthy of her gratitude; but shall I likewise return worthy of your love?"

The young woman only replied by the beautiful glow which mounted to her cheeks. A few seconds afterward d'Artagnan also went out enveloped in a large cloak, which ill-concealed the sheath of a long sword.

Mme. Bonacieux followed him with her eyes, with that long, fond look with which he had turned the angle of the street, she fell on her knees, and clasping her hands, "Oh, my God," cried she, "protect the queen, protect me!"

D'Artagnan went straight to M. de Treville's. He had reflected that in a few minutes the cardinal would be warned by this cursed stranger, who appeared to be his agent, and he judged, with reason, he had not a moment to lose.

The heart of the young man overflowed with joy. An opportunity presented itself to him in which there would be at the same time glory to be acquired, and money to be gained; and as a far higher encouragement, it brought him into close intimacy with with a woman he adored. This chance did, then, for him at once more than he would have dared to ask of Providence.

M. de Treville was in his saloon with his habitual court of gentlemen. D'Artagnan, who was known as a familiar of the house, went straight to his office, and sent word that he wished to see him on something of importance.

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?"

So far I have been able to quote from the reports which I have forwarded during these early days to Sherlock Holmes. Now, however, I have arrived at a point in my narrative where I am compelled to abandon this method and to trust once more to my recollections, aided by the diary which I kept at the time. A few extracts from the latter will carry me on to those scenes which are indelibly fixed in every detail upon my memory. I proceed, then, from the morning which followed our abortive chase of the convict and our other strange experiences upon the moor.

OCTOBER 16TH.—A dull and foggy day with a drizzle of rain. The house is banked in with rolling clouds, which rise now and then to show the dreary curves of the moor, with thin, silver veins upon the sides of the hills, and the distant boulders gleaming where the light strikes upon their wet faces. It is melancholy outside and in. The baronet is in a black reaction after the excitements of the night. I am conscious myself of a weight at my heart and a feeling of impending danger—ever present danger, which is the more terrible because I am unable to define it.

And have I not cause for such a feeling? Consider the long sequence of incidents which have all pointed to some sinister influence which is at work around us. There is the death of the last occupant of the Hall, fulfilling so exactly the conditions of the family legend, and there are the repeated reports from peasants of the appearance of a strange creature upon the moor. Twice I have with my own ears heard the sound which resembled the distant baying of a hound. It is incredible, impossible, that it should really be outside the ordinary laws of nature. A spectral hound which leaves material footmarks and fills the air with its howling is surely not to be thought of. Stapleton may fall in with such a superstition, and Mortimer also; but if I have one quality upon earth it is common-sense, and nothing will persuade me to believe in such a thing. To do so would be to descend to the level of these poor peasants, who are not content with a mere fiend dog but must needs describe him with hell-fire shooting from his mouth and eyes. Holmes would not listen to such fancies, and I am his agent. But facts are facts, and I have twice heard this crying upon the moor. Suppose that there were really some huge hound loose upon it; that would go far to explain everything. But where could such a hound lie concealed, where did it get its food, where did it come from, how was it that no one saw it by day? It must be confessed that the natural explanation offers almost as many difficulties as the other. And always, apart from the hound, there is the fact of the human agency in London, the man in the cab, and the letter which warned Sir Henry against the moor. This at least was real, but it might have been the work of a protecting friend as easily as of an enemy. Where is that friend or enemy now? Has he remained in London, or has he followed us down here? Could he—could he be the stranger whom I saw upon the tor?
