"Very well. It may, however, have been written on Monday and only posted to-day."

"That is possible."

"If so, much may have happened between."

"Oh, you must not discourage me, Mr. Holmes. I know that all is well with him. There is so keen a sympathy between us that I should know if evil came upon him. On the very day that I saw him last he cut himself in the bedroom, and yet I in the dining-room rushed upstairs instantly with the utmost certainty that something had happened. Do you think that I would respond to such a trifle and yet be ignorant of his death?"

"I have seen too much not to know that the impression of a woman may be more valuable than the conclusion of an analytical reasoner. And in this letter you certainly have a very strong piece of evidence to corroborate your view. But if your husband is alive and able to write letters, why should he remain away from you?"

"I cannot imagine. It is unthinkable."

"And on Monday he made no remarks before leaving you?"

"No."

"And you were surprised to see him in Swandam Lane?"

"Very much so."

"Was the window open?"

"Yes."

"Then he might have called to you?"

"He might."

"He only, as I understand, gave an inarticulate cry?"

"Yes."

"A call for help, you thought?"

"Yes. He waved his hands."

"But it might have been a cry of surprise. Astonishment at the unexpected sight of you might cause him to throw up his hands?"
