"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, 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.
"Driving back in the evening from Coombe Tracey he was in time to get his hound, to treat it with his infernal paint, and to bring the beast round to the gate at which he had reason to expect that he would find the old gentleman waiting. The dog, incited by its master, sprang over the wicket-gate and pursued the unfortunate baronet, who fled screaming down the Yew Alley. In that gloomy tunnel it must indeed have been a dreadful sight to see that huge black creature, with its flaming jaws and blazing eyes, bounding after its victim. He fell dead at the end of the alley from heart disease and terror. The hound had kept upon the grassy border while the baronet had run down the path, so that no track but the man's was visible. On seeing him lying still the creature had probably approached to sniff at him, but finding him dead had turned away again. It was then that it left the print which was actually observed by Dr. Mortimer. The hound was called off and hurried away to its lair in the Grimpen Mire, and a mystery was left which puzzled the authorities, alarmed the country-side, and finally brought-the case within the scope of our observation.
"So much for the death of Sir Charles Baskerville. You perceive the devilish cunning of it, for really it would be almost impossible to make a case against the real murderer. His only accomplice was one who could never give him away, and the grotesque, inconceivable nature of the device only served to make it more effective. Both of the women concerned in the case, Mrs. Stapleton and Mrs. Laura Lyons, were left with a strong suspicion against Stapleton. Mrs. Stapleton knew that he had designs upon the old man, and also of the existence of the hound. Mrs. Lyons knew neither of these things, but had been impressed by the death occurring at the time of an uncancelled appointment which was only known to him. However, both of them were under his influence, and he had nothing to fear from them. The first half of his task was successfully accomplished but the more difficult still remained.
"It is possible that Stapleton did not know of the existence of an heir in Canada. In any case he would very soon learn it from his friend Dr. Mortimer, and he was told by the latter all details about the arrival of Henry Baskerville. Stapleton's first idea was that this young stranger from Canada might possibly be done to death in London without coming down to Devonshire at all. He distrusted his wife ever since she had refused to help him in laying a trap for the old man, and he dared not leave her long out of his sight for fear he should lose his influence over her. It was for this reason that he took her to London with him. They lodged, I find, at the Mexborough Private Hotel, in Craven Street, which was actually one of those called upon by my agent in search of evidence. Here he kept his wife imprisoned in her room while he, disguised in a beard, followed Dr. Mortimer to Baker Street and afterwards to the station and to the Northumberland Hotel. His wife had some inkling of his plans; but she had such a fear of her husband—a fear founded upon brutal ill-treatment—that she dare not write to warn the man whom she knew to be in danger. If the letter should fall into Stapleton's hands her own life would not be safe. Eventually, as we know, she adopted the expedient of cutting out the words which would form the message, and addressing the letter in a disguised hand. It reached the baronet, and gave him the first warning of his danger.
"It was very essential for Stapleton to get some article of Sir Henry's attire so that, in case he was driven to use the dog, he might always have the means of setting him upon his track. With characteristic promptness and audacity he set about this at once, and we cannot doubt that the boots or chamber-maid of the hotel was well bribed to help him in his design. By chance, however, the first boot which was procured for him was a new one and, therefore, useless for his purpose. He then had it returned and obtained another—a most instructive incident, since it proved conclusively to my mind that we were dealing with a real hound, as no other supposition could explain this anxiety to obtain an old boot and this indifference to a new one. The more outré and grotesque an incident is the more carefully it deserves to be examined, and the very point which appears to complicate a case is, when duly considered and scientifically handled, the one which is most likely to elucidate it.
"Then we had the visit from our friends next morning, shadowed always by Stapleton in the cab. From his knowledge of our rooms and of my appearance, as well as from his general conduct, I am inclined to think that Stapleton's career of crime has been by no means limited to this single Baskerville affair. It is suggestive that during the last three years there have been
