A shade of anger and vengeance passed across the usually calm brow of this gentleman.

"It is impossible it can be she," said be. "How could this ring come into the hands of Milady Clarik? And yet it is difficult to suppose such a resemblance should exist between two jewels."

"Do you know this ring?" said d'Artagnan.

"I thought I did," replied Athos; "but no doubt I was mistaken." And he returned d'Artagnan the ring without, however, ceasing to look at it.

"Pray, d'Artagnan," said Athos, after a minute, "either take off that ring or turn the mounting inside; it recalls such cruel recollections that I shall have no head to converse with you. Don't ask me for counsel; don't tell me you are perplexed what to do. But stop! let me look at that sapphire again; the one I mentioned to you had one of its faces scratched by accident."

D'Artagnan took off the ring, giving it again to Athos.

Athos started. "Look," said he, "is it not strange?" and he pointed out to d'Artagnan the scratch he had remembered.

"But from whom did this ring come to you, Athos?"

"From my mother, who inherited it from her mother. As I told you, it is an old family jewel."

"And you--sold it?" asked d'Artagnan, hesitatingly.

"No," replied Athos, Athos with a singular smile. "I gave it away in a night of love, as it has been given to you."

D'Artagnan became pensive in his turn; it appeared as if there were abysses in Milady's soul whose depths were dark and unknown. He took back the ring, but put it in his pocket and not on his finger.

"d'Artagnan," said Athos, taking his hand, "you know I love you; if I had a son I could not love him better. Take my advice, renounce this woman. I do not know her, but a sort of intuition tells me she is a lost creature, and that there is something fatal about her."

"You are right," said d'Artagnan; "I will have done with her. I own that this woman terrifies me."

"Shall you have the courage?" said Athos.

"I shall," replied d'Artagnan, "and instantly."

"In truth, my young friend, you will act rightly," said the gentleman, pressing the Gascon's hand with an affection almost paternal; "and God grant that this woman, who has scarcely entered into your life, may not leave a terrible trace in it!" And Athos bowed to d'Artagnan like a man who wishes it understood that he would not be sorry to be left alone with his thoughts.

On reaching home d'Artagnan found Kitty waiting for him. A month of fever could not have changed her more than this one night of sleeplessness and sorrow.

She was sent by her mistress to the false de Wardes. Her mistress was mad with love, intoxicated with joy. She wished to know when her lover would meet her a second night; and poor Kitty, pale and trembling, awaited d'Artagnan's reply. The counsels of his friend, joined to the cries of his own heart, made him determine, now his pride was saved and his vengeance satisfied, not to see Milady again. As a reply, he wrote the following letter:

Do not depend upon me, madame, for the next meeting. Since my convalescence I have so many affairs of this kind on my hands that I am forced to regulate them a little. When your turn comes, I shall have the honor to inform you of it. I kiss your hands.

“Well, I’m glad to hear you say so,” said Sir Henry, glancing with some surprise at my friend. “I don’t pretend to know much about these things, and I’d be a better judge of a horse or a steer than of a picture. I didn’t know that you found time for such things.”

“I know what is good when I see it, and I see it now. That’s a Kneller, I’ll swear, that lady in the blue silk over yonder, and the stout gentleman with the wig ought to be a Reynolds. They are all family portraits, I presume?”

“Every one.”

“Do you know the names?”

“Barrymore has been coaching me in them, and I think I can say my lessons fairly well.”

“Who is the gentleman with the telescope?”

“That is Rear-Admiral Baskerville, who served under Rodney in the West Indies. The man with the blue coat and the roll of paper is Sir William Baskerville, who was Chairman of Committees of the House of Commons under Pitt.”

“And this Cavalier opposite to me—the one with the black velvet and the lace?”

“Ah, you have a right to know about him. That is the cause of all the mischief, the wicked Hugo, who started the Hound of the Baskervilles. We’re not likely to forget him.”

I gazed with interest and some surprise upon the portrait.

“Dear me!” said Holmes, “he seems a quiet, meek-mannered man enough, but I dare say that there was a lurking devil in his eyes. I had pictured him as a more robust and ruffianly person.”

“There’s no doubt about the authenticity, for the name and the date, 1647, are on the back of the canvas.”

Holmes said little more, but the picture of the old roysterer seemed to have a fascination for him, and his eyes were continually fixed upon it during supper. It was not until later, when Sir Henry had gone to his room, that I was able to follow the trend of his thoughts. He led me back into the banqueting-hall, his bedroom candle in his hand, and he held it up against the time-stained portrait on the wall.

“Do you see anything there?”

I looked at the broad plumed hat, the curling love-locks, the white lace collar, and the straight, severe face which was framed between them. It was not a brutal countenance, but it was prim, hard, and stern, with a firm-set, thin-lipped mouth, and a coldly intolerant eye.

“Is it like anyone you know?”

“There is something of Sir Henry about the jaw.”

“Just a suggestion, perhaps. But wait an instant!” He stood upon a chair, and, holding up the light in his left hand, he curved his right arm over the broad hat and round the long ringlets.

“Good heavens!” I cried, in amazement.

The face of Stapleton had sprung out of the canvas.

“Ha, you see it now. My eyes have been trained to examine faces and not their trimmings. It is the first quality of a criminal investigator that he should see through a disguise.”
