"Have you any objection to explain to me this apparent contradiction? It is impossible to believe that one, whose opinion of chloroform in relation to her was so fatal, would in a few hours cause her to inhale it."

Dr. Davenal stopped in his walk and confronted Oswald.

"Have you seen Mark since you came down?"

"Yes."

"And what does he say?"

"Well, I don't fancy he understands it much better than I do. He reiterates that it was given her for the best. In his opinion it may have been. But it surely could not have been in yours, Dr. Davenal."

Dr. Davenal turned from Oswald to his pacing again. A strong temptation was upon him to tell Oswald the truth. O that he had! that he had!

There were few people in the world whom he esteemed as he esteemed Oswald Cray. There was no one else in the world to whom he had expressed this opinion of the unfitness of Lady Oswald as a subject for chloroform, and the wish to explain, to exonerate himself, arose forcibly within him. The next moment he asked himself why Mark Cray himself had not spoken. As he had not, it seemed to Dr. Davenal that it would be a breach of friendship, of partnership, for him to speak. Oswald was connected, too, with Lady Oswald, and might take up the matter warmly. No, he felt in his ever-considerate heart that he could not betray Mark, could not set one brother against the other. And he put the temptation from him.

Oswald watched him as he walked, wondering at the silence. A silence which the doctor evidently did not feel inclined to break.

"Do you remember expressing this opinion to me, Dr. Davenal?"
