“He shall. I will see to that. Uncle and nephew have been murdered - the one frightened to death by the very sight of a beast which he thought to be supernatural, the other driven to his end in his wild flight to escape from it. But now we have to prove the connection between the man and the beast. Save from what we heard, we cannot even swear to the existence of the latter, since Sir Henry has evidently died from the fall. But, by heavens, cunning as he is, the fellow shall be in my power before another day is past!”

We stood with bitter hearts on either side of the mangled body, overwhelmed by this sudden and irrevocable disaster which had brought all our long and weary labours to so piteous an end. Then as the moon rose we climbed to the top of the rocks over which our poor friend had fallen, and from the summit we gazed out over the shadowy moor, half silver and half gloom. Far away, miles off, in the direction of Grimpen, a single steady yellow light was shining. It could only come from the lonely abode of the Stapletons. With a bitter curse I shook my fist at it as I gazed.

“Why should we not seize him at once?”

“Our case is not complete. The fellow is wary and cunning to the last degree. It is not what we know, but what we can prove. If we make one false move the villain may escape us yet.”

“What can we do?”

“There will be plenty for us to do to-morrow. To-night we can only perform the last offices to our poor friend.”

Together we made our way down the precipitous slope and approached the body, black and clear against the silvered stones. The agony of those contorted limbs struck me with a spasm of pain and blurred my eyes with tears.

“We must send for help, Holmes! We cannot carry him all the way to the Hall. Good heavens, are you mad?”

He had uttered a cry and bent over the body. Now he was dancing and laughing and wringing my hand. Could this be my stern, self-contained friend? These were hidden fires, indeed!

“A beard! A beard! The man has a beard!”

“A beard?”

“It is not the baronet - it is - why, it is my neighbour, the convict!”

With feverish haste we had turned the body over, and that dripping beard was pointing up to the cold, clear moon. There could be no doubt about the beetling forehead, the sunken animal eyes. It was indeed the same face which had glared upon me in the light of the candle from over the rock - the face of Selden, the criminal.

Then in an instant it was all clear to me. I remembered how the baronet had told me that he had handed his old wardrobe to Barrymore. Barrymore had passed it on in order to help Selden in his escape. Boots, shirt, cap - it was all Sir Henry’s. The tragedy was still black enough, but this man had at least deserved death by the laws of his country. I told Holmes how the matter stood, my heart bubbling over with thankfulness and joy.

“Then the clothes have been the poor devil’s death,” said he. “It is clear enough that the hound has been laid on from some article of Sir Henry’s - the boot which was abstracted in the hotel, in all probability - and so ran this man down. There is one very singular thing, however: How came Selden, in the darkness, to know that the hound was on his trail?”

“He heard him.”

“To hear a hound upon the moor would not work a hard man like this convict into such a paroxysm of terror that he would risk recapture by screaming wildly for help. By his cries he must have run a long way after he knew the animal was on his track. How did he know?”

“A greater mystery to me is why this hound, presuming that all our conjectures are correct- -”

“I presume nothing.”
