Every minute that white woolly plain which covered one half of the moor was drifting closer and closer to the house. Already the first thin wisps of it were curling across the golden square of the lighted window. The farther wall of the orchard was already invisible, and the trees were standing out of a swirl of white vapour. As we watched it the fog-wreaths came crawling round both corners of the house and rolled slowly into one dense bank, on which the upper floor and the roof floated like a strange ship upon a shadowy sea. Holmes struck his hand passionately upon the rock in front of us and stamped his feet in his impatience.

“If he isn’t out in a quarter of an hour the path will be covered. In half an hour we won’t be able to see our hands in front of us.”

“Shall we move farther back upon higher ground?”

“Yes, I think it would be as well.”

So as the fog-bank flowed onward we fell back before it until we were half a mile from the house, and still that dense white sea, with the moon silvering its upper edge, swept slowly and inexorably on.

“We are going too far,” said Holmes. “We dare not take the chance of his being overtaken before he can reach us. At all costs we must hold our ground where we are.” He dropped on his knees and clapped his ear to the ground. “Thank God, I think that I I hear him coming.”

A sound of quick steps broke the silence of the moor. Crouching among the stones we stared intently at the silver-tipped bank in front of us. The steps grew louder, and through the fog, as through a curtain, there stepped the man whom we were awaiting. He looked round him in surprise as he emerged into the clear, starlit night. Then he came swiftly along the path, passed close to where we lay, and went on up the long slope behind us. As he walked he glanced continually over either shoulder, like a man who is ill at ease.

“Hist!” cried Holmes, and I heard the sharp click of a cocking pistol. “Look out! It’s coming!”

There was a thin, crisp, continuous patter from somewhere in the heart of that crawling bank. The cloud was within fifty yards of where we lay, and we glared at it, all three, uncertain what horror was about to break from the heart of it. I was at Holmes’s elbow, and I glanced for an instant at his face. It was pale and exultant, his eyes shining brightly in the moonlight. But suddenly they started forward in a rigid, fixed stare, and his lips parted in amazement. At the same instant Lestrade gave a yell of terror and threw himself face downward upon the ground. I sprang to my feet, my inert hand grasping my pistol, my mind paralyzed by the dreadful shape which had sprung out upon us from the shadows of the fog. A hound it was, an enormous coal-black hound, but not such a hound as mortal eyes have ever seen. Fire burst from its open mouth, its eyes glowed with a smouldering glare, its muzzle and hackles and dewlap were outlined in flickering flame. Never in the delirious dream of a disordered brain could anything more savage, more appalling, more hellish be conceived than that dark form and savage face which broke upon us out of the wall of fog.

"Well, and what are you going to do at St. Germain?" then demanded Athos.

Then d'Artagnan described the meeting which he had at the church, and how he had found that lady who, with the seigneur in the black cloak and with the scar near his temple, filled his mind constantly.

"That is to say, you are in love with this lady as you were with Madame Bonacieux," said Athos, shrugging his shoulders contemptuously, as if he pitied human weakness.

"I? not at all!" said d'Artagnan. "I am only curious to unravel the mystery to which she is attached. I do not know why, but I imagine that this woman, wholly unknown to me as she is, and wholly unknown to her as I am, has an influence over my life."

"Well, perhaps you are right," said Athos. "I do not know a woman that is worth the trouble of being sought for when she is once lost. Madame Bonacieux is lost; so much the worse for her if she is found."

"No, Athos, no, you are mistaken," said d'Artagnan; "I love my poor Constance more than ever, and if I knew the place in which she is, were it at the end of the world, I would go to free her from the hands of her enemies; but I am ignorant. All my researches have been useless. What is to be said? I must divert my attention!"

"Amuse yourself with Milady, my dear d'Artagnan; I wish you may with all my heart, if that will amuse you."

"Hear me, Athos," said d'Artagnan. "Instead of shutting yourself up here as if you were under arrest, get on horseback and come and take a ride with me to St. Germain."

"My dear fellow," said Athos, "I ride horses when I have any; when I have none, I go afoot."

"Well," said d'Artagnan, smiling at the misanthropy of Athos, which from any other person would have offended him, "I ride what I can get; I am not so proud as you. So AU REVOIR, dear Athos."

"AU REVOIR," said the Musketeer, making a sign to Grimaud to uncork the bottle he had just brought.

D'Artagnan and Planchet mounted, and took the road to St. Germain.

All along the road, what Athos had said respecting Mme. Bonacieux recurred to the mind of the young man. Although d'Artagnan was not of a very sentimental character, the mercer's pretty wife had made a real impression upon his heart. As he said, he was ready to go to the end of the world to seek her; but the world, being round, has many ends, so that he did not know which way to turn. Meantime, he was going to try to find out Milady. Milady had spoken to the man in the black cloak; therefore she knew him. Now, in the opinion of d'Artagnan, it was certainly the man in the black cloak who had carried off Mme. Bonacieux the second time, as he had carried her off the first. d'Artagnan then only half-lied, which is lying but little, when he said that by going in search of Milady he at the same time went in search of Constance.

Thinking of all this, and from time to time giving a touch of the spur to his horse, d'Artagnan completed his short journey, and arrived at St. Germain. He had just passed by the pavilion in which ten years later Louis XIV was born. He rode up a very quiet street, looking to the right and the left to see if he could catch any vestige of his beautiful Englishwoman, when from the ground floor of a pretty house, which, according to the fashion of the time, had no window toward the street, he saw a face peep out with which he thought he was acquainted. This person walked along the terrace, which was ornamented with flowers. Planchet recognized him first.
