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, with a singular smile. "I Reference 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.

“A touch, Watson—an undeniable touch!” said he. “I feel a foil as quick and supple as my own. He got home upon me very prettily that time. So his name was Sherlock Holmes, was it?”

“Yes, sir, that was the gentleman’s name.”

“Excellent! Tell me where you picked him up and all that occurred.”

“He hailed me at half-past nine in Trafalgar Square. He said that he was a detective, and he offered me two guineas if I would do exactly what he wanted all day and ask no questions. I was glad enough to agree. First we drove down to the Northumberland Hotel and waited there until two gentlemen came out and took a cab from the rank. We followed their cab until it pulled up somewhere near here.”

“This very door,” said Holmes.

“Well, I couldn’t be sure of that, but I dare say my fare knew all about it. We pulled up half-way down the street and waited an hour and a half. Then the two gentlemen passed us, walking, and we followed down Baker Street and along —”

“I know,” said Holmes.

“Until we got three-quarters down Regent Street. Then my gentleman threw up the trap, and he cried that I should drive right away to Waterloo Station as hard as I could go. I whipped up the mare and we were there under the ten minutes. Then he paid up his two guineas, like a good one, and away he went into the station. Only just as he was leaving he turned round and he said: ‘It might interest you to know that you have been driving Mr. Sherlock Holmes.’ That’s how I come to know the name.”

“I see. And you saw no more of him?”

“Not after he went into the station.”

“And how would you describe Mr. Sherlock Holmes?”

The cabman scratched his head. “Well, he wasn’t altogether such an easy gentleman to describe. I’d put him at forty years of age, and he was of a middle height, two or three inches shorter than you, sir. He was dressed like a toff, and he had a black beard, cut square at the end, and a pale face. I don’t know as I could say more than that.”

“Colour of his eyes?”

“No, I can’t say that.”

“Nothing more that you can remember?”

“No, sir; nothing.”

“Well, then, here is your half-sovereign. There’s another one waiting for you if you can bring any more information. Good night!”

“Good night, sir, and thank you!”

John Clayton departed chuckling, and Holmes turned to me with a shrug of his shoulders and a rueful smile.

“Snap goes our third thread, and we end where we began,” said he. “The cunning rascal! He knew our number, knew that Sir Henry Baskerville had consulted me, spotted who I was in Regent Street, conjectured that I had got the number of the cab and would lay my hands on the driver, and so sent back this audacious message. I tell you, Watson, this time we have got a foeman who is worthy of our steel. I’ve been checkmated in London. I can only wish you better luck in Devonshire. But I’m not easy in my mind about it.”
