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 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 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.

"Very well," said the gentleman. And, with his lackey, he took the road to the governor's country house.

D'Artagnan and Planchet followed the gentleman at a distance of five hundred paces. Once outside the city, d'Artagnan overtook the gentleman as he was entering a little wood.

"Monsieur, you appear to be in great haste?"

"No one can be more so, monsieur."

"I am sorry for that," said d'Artagnan; "for as I am in great haste likewise, I wish to beg you to render me a service."

"What?"

"To let me sail first."

"That's impossible," said the gentleman; "I have traveled sixty leagues in forty hours, and by tomorrow at midday I must be in London."

"I have performed that same distance in forty hours, and by ten o'clock in the morning I must be in London."

"Very sorry, monsieur; but I was here first, and will not sail second."

"I am sorry, too, monsieur; but I arrived second, and must sail first."

"The king's service!" said the gentleman.

"My own service!" said d'Artagnan.

"But this is a needless quarrel you seek with me, as it seems to me."

"PARBLEU! What do you desire it to be?"

"What do you want?"

"Would you like to know?"

"Certainly."

"Well, then, I wish that order of which you are bearer, seeing that I have not one of my own and must have one."

"You jest, I presume."

"I never jest."

"Let me pass!"

"You shall not pass."

"My brave young man, I will blow out your brains. HOLA, Lubin, my pistols!"

"Planchet," called out d'Artagnan, "take care of the lackey; I will manage the master."

Planchet, emboldened by the first exploit, sprang upon Lubin; and being strong and vigorous, he soon got him on the broad of his back, and placed his knee upon his breast.

"Go on with your affair, monsieur," cried Planchet; "I have finished mine."

Seeing this, the gentleman drew his sword, and sprang upon d'Artagnan; but he had too strong an adversary. In three seconds d'Artagnan had wounded him three times, exclaiming at each thrust, "One for Athos, one for Porthos; and one for Aramis!"

At the third hit the gentleman fell like a log. D'Artagnan believed him to be dead, or at least insensible, and went toward him for the purpose of taking the order; but the moment he extended his hand to search for it, the wounded man, who had not dropped his sword, plunged the point into d'Artagnan's breast, crying, "One for you!"

"And one for me--the best for last!" cried d'Artagnan, furious, nailing him to the earth with a fourth thrust through his body.

This time the gentleman closed his eyes and fainted. D'Artagnan searched his pockets, and took from one of them the order for the passage. It was in the name of Comte de Wardes.

Then, casting a glance on the handsome young man, who was scarcely twenty-five years of age, and whom he was leaving in his gore, deprived of sense and perhaps dead, he gave a sigh for that unaccountable destiny which leads men to destroy each other for the interests of people who are strangers to them and who often do not even know that they exist. But he was soon aroused from these reflections by Lubin, who uttered loud cries and screamed for help with all his might.
