"Yes," said Rendel, and a sudden idea occurred to him, to be dismissed as soon as entertained, "Sir William Gore."

"Gore?" said Stamfordham, looking at Rendel, but forbearing any comment on his father-in-law.

"It was quite impossible," Rendel said decidedly, answering Stamfordham's unspoken words, "that he could have got at the papers; for, as I told you, when I came back again they were exactly where I had left them, and the thing locked with this very complicated key, and he showed it hanging on his chain."

"It is evident," Stamfordham repeated inflexibly, "that some one must have got hold of it with or without your knowledge. I warned you yesterday, you remember, about taking your—any one in your household into your confidence."

"And I did not," Rendel said, grasping his meaning. "My wife did not even know that I had the papers to transcribe. She does not know it now."

Stamfordham paused a moment. He could not in words accuse Rendel's wife, whatever his silence might imply. Then he spoke with emphatic sternness.

"Rendel," he said, "by whatever means the thing happened, we must know how. I must have an explanation."

Rendel was powerless to speak.

"For you must see," Stamfordham went on, "what a terrible catastrophe this might have been—the danger is not over yet, in fact, although I may be strong enough for my colleagues to condone the fact that the public has been told of this before themselves, and the country may be strong enough for foreign Powers to do the same. But, as a personal matter, I must know how it got out, and I repeat, I must have an explanation. For your own sake you must explain."

Rendel felt as if the ground were reeling under his feet.
