"And do you mean to say that there is nothing that can throw any light upon it, no possible solution?"
"I can throw no light," said Rendel.
"But...." said Stamfordham. "Is this all you are going to say? Have you thought of no possibility? Have you no suggestion to offer?"
"I am afraid," said Rendel again, "that I can offer none."
Lord Stamfordham sat silent for a moment, absolutely bewildered. Part of his exceptional administrative ability was the almost unerring judgment he displayed in choosing those he employed about him, and it was an entirely new experience to him to have to suspect one of them, or to impugn the ordinary code of honourable conduct. He found it extremely difficult, autocrat as he was, to put it into words. He was sore and angry at the grave indiscretion, if not something worse, that had been committed, most of all that it should have been himself, the great officer of state, in whom it was unpardonable to choose the wrong tool, who had put that immeasurably important secret into the hands of a man who had somehow or other let it escape from them; so much could not be denied. It certainly seemed difficult to conceive that it should be Rendel himself who had betrayed it, or that if he had betrayed it he would not admit the fact. And yet—could it be?—there was something in Rendel's demeanour now that made it more possible than it had been an hour ago to credit him with the shameful possibility. The pause during which all this had rushed through Stamfordham's mind seemed to Rendel to have lasted through untold ages of time, when Stamfordham at last spoke again.
"Rendel," he said, "I have a right to demand that you should give me more satisfaction than this. You say you have learnt nothing, and can tell me nothing, but this I find impossible to believe." Rendel made a movement. "I am sorry, but I say this advisedly, since this disclosure must have taken place in your house," and he underlined the words emphatically. "I can't think it possible that a man of your intelligence should not have found some clue, some possible suggestion."
"I am very sorry," said Rendel. "I'm afraid I have not."
"Then, of course, it is obvious what conclusion I must come to," said Lord Stamfordham. "That it is not that you cannot give any explanation, but that you decline to give it."
Rendel, to his intense mortification, felt that he was changing colour. Stamfordham, looking at him earnestly, felt absolutely certain that he knew.
