But there were ample signs that I had not come upon a false scent. This was certainly where the man lived. Some blankets rolled in a waterproof lay upon that very stone slab upon which Neolithic man had once slumbered. The ashes of a fire were heaped in a rude grate. Beside it lay some cooking utensils and a bucket half-full of water. A litter of empty tins showed that the place had been occupied for some time, and I saw, as my eyes became accustomed to the checkered light, a pannikin and a half-full bottle of spirits standing in the corner. In the middle of the hut a flat stone served the purpose of a table, and upon this stood a small cloth bundle—the same, no doubt, which I had seen through the telescope upon the shoulder of the boy. It contained a loaf of bread, a tinned tongue, and two tins of preserved peaches. As I set it down again, after having examined it, my heart leaped to see that beneath it there lay a sheet of paper with writing upon it. I raised it, and this was what I read, roughly scrawled in pencil:—

Dr. Watson has gone to Coombe Tracey.

For a minute I stood there with the paper in my hands thinking out the meaning of this curt message. It It was I, then, and not Sir Henry, who was being dogged by this secret man. He had not followed me himself, but he had set an agent—the boy, perhaps—upon my track, and this was his report. Possibly I had taken no step since I had been upon the moor which had not been observed and reported. Always there was this feeling of an unseen force, a fine net drawn round us with infinite skill and delicacy, holding us so lightly that it was only at some supreme moment that one realized that one was indeed entangled in its meshes.

If there was one report there might be others, so I looked round the hut in search of them. There was no trace, however, of anything of the kind, nor could I discover any sign which might indicate the character or intentions of the man who lived in this singular place, save that he must be of Spartan habits and cared little for the comforts of life. When I thought of the heavy rains and looked at the gaping roof I understood how strong and immutable must be the purpose which had kept him in that inhospitable abode. Was he our malignant enemy, or was he by chance our guardian angel? I swore that I would not leave the hut until I knew.

Outside the sun was sinking low and the west was blazing with scarlet and gold. Its reflection was shot back in ruddy patches by the distant pools which lay amid the great Grimpen Mire. There were the two towers of Baskerville Hall, and there a distant blur of smoke which marked the village of Grimpen. Between the two, behind the hill, was the house of the Stapletons. All was sweet and mellow and peaceful in the golden evening light, and yet as I looked at them my soul shared none of the peace of nature but quivered at the vagueness and the terror of that interview which every instant was bringing nearer. With tingling nerves, but a fixed purpose, I sat in the dark recess of the hut and waited with sombre patience for the coming of its tenant.

"Great God!" cried d'Artagnan, loosing his hold of her dress, and remaining mute, motionless, and frozen.

But Milady felt herself denounced even by his terror. He had doubtless seen all. The young man now knew her secret, her terrible secret--the secret she concealed even from her maid with such care, the secret of which all the world was ignorant, except himself.

She turned upon him, no longer like a furious woman, but like a wounded panther.

"Ah, wretch!" cried she, "you have basely betrayed me, and still more, you have my secret! You shall die."

And she flew to a little inlaid casket which stood upon the dressing table, opened it with a feverish and trembling band, drew from it a small poniard, with a golden haft and a sharp thin blade, and then threw herself with a bound upon d'Artagnan.

Although the young man was brave, as we know, he was terrified at that wild countenance, those terribly dilated pupils, those pale cheeks, and those bleeding lips. He recoiled to the other side of the room as he would have done from a serpent which was crawling toward him, and his sword coming in contact with his nervous hand, he drew it almost unconsciously from the scabbard. But without taking any heed of the sword, Milady endeavored to get near enough to him to stab him, and did not stop till she felt the sharp point at her throat.

She then tried to seize the sword with her hands; but d'Artagnan kept it free from her grasp, and presenting the point, sometimes at her eyes, sometimes at her breast, compelled her to glide behind the bedstead, while he aimed at making his retreat by the door which led to Kitty's apartment.

Milady during this time continued to strike at him with horrible fury, screaming in a formidable way.

As all this, however, bore some resemblance to a duel, d'Artagnan began to recover himself little by little.

"Well, beautiful lady, very well," said he; "but, PARDIEU, if you don't calm yourself, I will design a second FLEUR-DE-LIS upon one of those pretty checks!"

"Scoundrel, infamous scoundrel!" howled Milady.

But d'Artagnan, still keeping on the defensive, drew near to Kitty's door. At the noise they made, she in overturning the furniture in her efforts to get at him, he in screening himself behind the furniture to keep out of her reach, Kitty opened the door. D'Artagnan, who had unceasingly maneuvered to gain this point, was not at more than three paces from it. With one spring he flew from the chamber of Milady into that of the maid, and quick as lightning, he slammed to the door, and placed all his weight against it, while Kitty pushed the bolts.

Then Milady attempted to tear down the doorcase, with a strength apparently above that of a woman; but finding she could not accomplish this, she in her fury stabbed at the door with her poniard, the point of which repeatedly glittered through the wood. Every blow was accompanied with terrible imprecations.

"Quick, Kitty, quick!" said d'Artagnan, in a low voice, as soon as the bolts were fast, "let me get out of the hotel; for if we leave her time to turn round, she will have me killed by the servants."
