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 gave it away in a night of 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.

The whole steep slope was covered with gray circular rings of stone, a score of them at least.

“What are they? Sheep-pens?”

“No, they are the homes of our worthy ancestors. Prehistoric man lived thickly on the moor, and as no one in particular has lived there since, we find all his little arrangements exactly as he left them. These are his wigwams with the roofs off. You can even see his hearth and his couch if you have the curiosity to go inside.

“But it is quite a town. When was it inhabited?”

“Neolithic man—no date.”

“What did he do?”

“He grazed his cattle on these slopes, and he learned to dig for tin when the bronze sword began to supersede the stone axe. Look at the great trench in the opposite hill. That is his mark. Yes, you will find some very singular points about the moor, Dr. Watson. Oh, excuse me an instant! It is surely Cyclopides.”

A small fly or moth had fluttered across our path, and in an instant Stapleton was rushing with extraordinary energy and speed in pursuit of it. To my dismay the creature flew straight for the great mire, and my acquaintance never paused for an instant, bounding from tuft to tuft behind it, his green net waving in the air. His gray clothes and jerky, zigzag, irregular progress made him not unlike some huge moth himself. I was standing watching his pursuit with a mixture of admiration for his extraordinary activity and fear lest he should lose his footing in the treacherous mire, when I heard the sound of steps, and turning round found a woman near me upon the path. She had come from the direction in which the plume of smoke indicated the position of Merripit House, but the dip of the moor had hid her until she was quite close.

I could not doubt that this was the Miss Stapleton of whom I had been told, since ladies of any sort must be few upon the moor, and I remembered that I had heard someone describe her as being a beauty. The woman who approached me was certainly that, and of a most uncommon type. There could not have been a greater contrast between brother and sister, for Stapleton was neutral tinted, with light hair and gray eyes, while she was darker than any brunette whom I have seen in England—slim, elegant, and tall. She had a proud, finely cut face, so regular that it might have seemed impassive were it not for the sensitive mouth and the beautiful dark, eager eyes. With her perfect figure and elegant dress she was, indeed, a strange apparition upon a lonely moorland path. Her eyes were on her brother as I turned, and then she quickened her pace towards me. I had raised my hat and was about to make some explanatory remark, when her own words turned all my thoughts into a new channel.

“Go back!” she said. “Go straight back to London, instantly.”

I could only stare at her in stupid surprise. Her eyes blazed at me, and she tapped the ground impatiently with her foot.

“Why should I go back?” I asked.

“I cannot explain.” She spoke in a low, eager voice, with a curious lisp in her utterance. “But for God’s sake do what I ask you. Go back and never set foot upon the moor again.”
