"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 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 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?"

It was the end of November and Holmes and I sat, upon a raw and foggy night, on either side of a blazing fire in our sitting-room in Baker Street. Since the tragic upshot of our visit to Devonshire he had been engaged in two affairs of the utmost importance, in the first of which he had exposed the atrocious conduct of Colonel Upwood in connection with the famous card scandal of the Nonpareil Club, while in the second he had defended the unfortunate Mme. Montpensier from the charge of murder which hung over her in connection with the death of her step-daughter, Mlle. Carere, the young lady who, as it will be remembered, was found six months later alive and married in New York. My friend was in excellent spirits over the success which had attended a succession of difficult and important cases, so that I was able to induce him to discuss the details of the Baskerville mystery. I had waited patiently for the opportunity, for I was aware that he would never permit cases to overlap, and that his clear and logical mind would not be drawn from its present work to dwell upon memories of the past. Sir Henry and Dr. Mortimer were, however, in London, on their way to that long voyage which had been recommended for the restoration of his shattered nerves. They had called upon us that very afternoon, so that it was natural that the subject should come up for discussion.

“The whole course of events,” said Holmes, “from the point of view of the man who called himself Stapleton was simple and direct, although to us, who had no means in the beginning of knowing the motives of his actions and could only learn part of the facts, it all appeared exceedingly complex. I have had the advantage of two conversations with Mrs. Stapleton, and the case has now been so entirely cleared up that I am not aware that there is anything which has remained a secret to us. You will find a few notes upon the matter under the heading B in my indexed list of cases.”

“Perhaps you would kindly give me a sketch of the course of events from memory.”

“Certainly, though I cannot guarantee that I carry all the facts in my mind. Intense mental concentration has a curious way of blotting out what has passed. The barrister who has his case at his fingers’ ends, and is able to argue with an expert upon his own subject finds that a week or two of the courts will drive it all out of his head once more. So each of my cases displaces the last, and Mlle. Carere has blurred my recollection of Baskerville Hall. To-morrow some other little problem may be submitted to my notice which will in turn dispossess the fair French lady and the infamous Upwood. So far as the case of the Hound goes, however, I will give you the course of events as nearly as I can, and you will suggest anything which I may have forgotten.

“My inquiries show beyond all question that the family portrait did not lie, and that this fellow was indeed a Baskerville. He was a son of that Rodger Baskerville, the younger brother of Sir Charles, who fled with a sinister reputation to South America, where he was said to have died unmarried. He did, as a matter of fact, marry, and had one child, this fellow, whose real name is the same as his father’s. He married Beryl Garcia, one of the beauties of Costa Rica, and, having purloined a considerable sum of public money, he changed his name to Vandeleur and fled to England, where he established a school in the east of Yorkshire. His reason for attempting this special line of business was that he had struck up an acquaintance with a consumptive tutor upon the voyage home, and that he had used this man’s ability to make the undertaking a success. Fraser, the tutor, died however, and the school which had begun well sank from disrepute into infamy. The Vandeleurs found it convenient to change their name to Stapleton, and he brought the remains of his fortune, his schemes for the future, and his taste for entomology to the south of England. I learned at the British Museum that he was a recognized authority upon the subject, and that the name of Vandeleur has been permanently attached to a certain moth which he had, in his Yorkshire days, been the first to describe.
