“We now come to that portion of his life which has proved to be of such intense interest to us. The fellow had evidently made inquiry and found that only two lives intervened between him and a valuable estate. When he went to Devonshire his plans were, I believe, exceedingly hazy, but that he meant mischief from the first is evident from the way in which he took his wife with him in the character of his sister. The idea of using her as a decoy was clearly already in his mind, though he may not have been certain how the details of his plot were to be arranged. He meant in the end to have the estate, and he was ready to use any tool or run any risk for that end. His first act was to establish himself as near to his ancestral home as he could, and his second was to cultivate a friendship with Sir Charles Baskerville and with the neighbours.

“The baronet himself told him about the family hound, and so prepared the way for his own death. Stapleton, as I will continue to call him, knew that the old man’s heart was weak and that a shock would kill him. So much he had learned from Dr. Mortimer. He had heard also that Sir Charles was superstitious and had taken this grim legend very seriously. His ingenious mind instantly suggested a way by which the baronet could be done to death, death and yet it would be hardly possible to bring home the guilt to the real murderer.

“Having conceived the idea he proceeded to carry it out with considerable finesse. An ordinary schemer would have been content to work with a savage hound. The use of artificial means to make the creature diabolical was a flash of genius upon his part. The dog he bought in London from Ross and Mangles, the dealers in Fulham Road. It was the strongest and most savage in their possession. He brought it down by the North Devon line and walked a great distance over the moor so as to get it home without exciting any remarks. He had already on his insect hunts learned to penetrate the Grimpen Mire, and so had found a safe hiding-place for the creature. Here he kennelled it and waited his chance.

“But it was some time coming. The old gentleman could not be decoyed outside of his grounds at night. Several times Stapleton lurked about with his hound, but without avail. It was during these fruitless quests that he, or rather his ally, was seen by peasants, and that the legend of the demon dog received a new confirmation. He had hoped that his wife might lure Sir Charles to his ruin, but here she proved unexpectedly independent. She would not endeavour to entangle the old gentleman in a sentimental attachment which might deliver him over to his enemy. Threats and even, I am sorry to say, blows refused to move her. She would have nothing to do with it, and for a time Stapleton was at a deadlock.

“He found a way out of his difficulties through the chance that Sir Charles, who had conceived a friendship for him, made him the minister of his charity in the case of this unfortunate woman, Mrs. Laura Lyons. By representing himself as a single man he acquired complete influence over her, and he gave her to understand that in the event of her obtaining a divorce from her husband he would marry her. His plans were suddenly brought to a head by his knowledge that Sir Charles was about to leave the Hall on the advice of Dr. Mortimer, with whose opinion he himself pretended to coincide. He must act at once, or his victim might get beyond his power. He therefore put pressure upon Mrs. Lyons to write this letter, imploring the old man to give her an interview on the evening before his departure for London. He then, by a specious argument, prevented her from going, and so had the chance for which he had waited.

"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."
