“I entirely believe you, madam,” said Sherlock Holmes. “The recital of these events must be very painful to you, and perhaps it will make it easier if I tell you what occurred, and you can check me if I make any material mistake. The sending of this letter was suggested to you by Stapleton?”

“He dictated it.”

“I presume that the reason he gave was that you would receive help from Sir Charles for the legal expenses connected with your divorce?”

“Exactly.”

“And then after you had sent the letter he dissuaded you from keeping the appointment?”

“He told me that it would hurt his self-respect that any other man should find the money for such an object, and that though he was a poor man himself he would devote his last penny to removing the obstacles which divided us.”

“He appears to be a very consistent character. And then you heard nothing until you read the reports of the death in the paper?”

“No.”

“And he made you swear to say nothing about your appointment with Sir Charles?”

“He did. He said that the death was a very mysterious one, and that I should certainly be suspected if the facts came out. He frightened me into remaining silent.”

“Quite so. But you had your suspicions?”

She hesitated and looked down.

“I knew him,” she said. “But if he had kept faith with me I should always have done so with him.”

“I think that on the whole you have had a fortunate escape,” said Sherlock Holmes. “You have had him in your power and he knew it, and yet you are alive. You have been walking for some months very near to the edge of a precipice. We must wish you good-morning now, Mrs. Lyons, and it is probable that you will very shortly hear from us again.”

“Our case becomes rounded off, and difficulty after difficulty thins away in front of us,” said Holmes as we stood waiting for the arrival of the express from town. “I shall soon be in the position of being able to put into a single connected narrative one of the most singular and sensational crimes of modern times. Students of criminology will remember the analogous incidents in Godno, in Little Russia, in the year ’66, and of course there are the Anderson murders in North Carolina, but this case possesses some features which are entirely its own. Even now we have no clear case against this very wily man. But I shall be very much surprised if it is not clear enough before we go to bed this night.”
