“Thank God! Thank God! Oh, this villain! See how he has treated me!” She shot her arms out from her sleeves, and we saw with horror that they were all mottled with bruises. “But this is nothing—nothing! It is my mind and soul that he has tortured and defiled. I could endure it all, ill-usage, solitude, a life of deception, everything, as long as I could still cling to the hope that I had his love, but now I know that in this also I have been his dupe and his tool.” She broke into passionate sobbing as she spoke.

“You bear him no good will, madam,” said Holmes. “Tell us then where we shall find him. If you have ever aided him in evil, help us now and so atone.”

“There is but one place where he can have fled,” she answered. “There is an old tin mine on an island in the heart of the mire. It was there that he kept his hound and there also he had made preparations so that he might have a refuge. That is where he would fly.”

The fog-bank lay like white wool against the window. Holmes held the lamp towards it.

“See,” said he. “No one could find his way into the Grimpen Mire tonight.”

She laughed and clapped her hands. Her eyes and teeth gleamed with fierce merriment.

“He may find his way in, but never out,” she cried. “How can he see the guiding wands tonight? We planted them together, he and I, to mark the pathway through the mire. Oh, if I could only have plucked them out today. Then indeed you would have had him at your mercy!”

It was evident to us that all pursuit was in vain until the fog had lifted. Meanwhile we left Lestrade in possession of the house while Holmes and I went back with the baronet to Baskerville Hall. The story of the Stapletons could no longer be withheld from him, but he took the blow bravely when he learned the truth about the woman whom he had loved. But the shock of the night’s adventures had shattered his nerves, and before morning he lay delirious in a high fever under the care of Dr. Mortimer. The two of them were destined to travel together round the world before Sir Henry had become once more the hale, hearty man that he had been before he became master of that ill-omened estate.
