“Do not believe him, my Lord,” urged Greening, his light, womanish voice roughened by rage and disappointment. “If I cannot answer for the name of the mountain, I can, by God, for the rest! Had you seen the prisoner’s face when I read over to him next morning what he had told me, you would know that his description was accurate enough. It is only a question of finding out which mountain he had in mind, and if your Lordship will give me half an hour or so with him——”

Lord Loudoun turned on him. “You have mismanaged this business quite enough,” he snapped. “I do not desire you, Captain Greening, to meddle with it any further. Nor is Mr. Cameron asleep now.”

There was that in Captain Greening’s expression as he turned away, biting his lip, which suggested that he would not consider that state necessary for his purpose.

Ewen shut his eyes and leant his head against the wall. The Earl and his two officers were talking together in low voices, and he longed for them to go away and leave him to turn over, as if it were a grain of gold out of a muddy river, the thought of this wonderful and saving slip of the tongue. He could not understand how he came to have stumbled so mercifully; was it because in his illness he fancied himself at times back in the shieling on that mountain which was, he believed, called Beinn Laoigh, the calf’s mountain? That he had not himself noticed the mistake in the name when Captain Greening read over to him, next morning, what he was pleased to call his deposition, he could, after all, understand; the horror of the accuracy of the rest had too much swamped his soul. He tried now to calculate how much security was given back to the secret place by his happy blunder, but it was not easy.

Then he heard a movement to the door. Thank God, they had done with him! No, feet were approaching him again. He opened his eyes and saw Lord Loudoun standing looking out through one of the narrow windows only a few feet away. Save for him, the room was empty, though the door remained ajar. Evidently the Earl desired a measure of privacy.

“I am very sorry about your treatment, Mr. Cameron,” he began, his eyes still fixed on the narrow slit. “It has been an unfortunate business.”

“Which, my Lord,” asked Ewen coolly, “my treatment or the information which proves to be worthless?”

“I referred, naturally, to your treatment,” said Lord Loudoun with dignity (but Ewen did not feel so sure). “However, you must admit that I may fairly consider the other affair a . . . disappointment. As a soldier, with my duty to carry out, I must avail myself of any weapon to my hand.”

“Evidently,” commented his prisoner. “Even of one which is not very clean!”

Lord Loudoun sighed. “Alas, one cannot always choose. You yourself, Mr. Cameron, had no choice in the matter of your disclosure, and are therefore in no sense to blame. . . . I should wish everyone to know that,” he added graciously, turning round and looking down at him.
