“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 countryside, 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.
