Keith thanked him for the assurance, but he was not really listening. Ewen Cameron was somewhere in this half-ruined enclosure.

His new quarters turned out to be bare, but not more so, certainly, than the tent. In the night, tossing on the camp bed, he made up his mind that if it proved impossible to obtain access to Ardroy in person, he would at least contrive to get a letter smuggled in to him somehow. Surely he could find a venal sentry or gaoler. He wondered what his own custodian was like, for on arrival, being much absorbed in his own thoughts, he had only received an impression of someone stout and middle-aged.

Morning and breakfast revealed him; a sergeant who might have been a well-to-do sufferer from gout, so painfully did he hobble in with the meal. Talkative upon encouragement, and apologetic for his bodily shortcomings, he explained that his lameness was due to a wound in the foot received when Fort Augustus was besieged by the Highlanders, he being a sergeant of Guise’s regiment, three companies of which then held it. When they surrendered and marched out, he was left behind. “And though I looked to have my throat cut, sir, by the wild MacDonalds and what not, I was very well treated, and my wound cared for. Is this what you wish for breakfast, sir?”

“I am not in a position to exercise much choice,” said Keith. “You know that Lord Loudoun has put me under arrest?”

The stout sergeant seemed shocked at this blunt reference to an unfortunate fact. “If I may presume on your being English, sir, same as I am myself——”

“You may,” replied Keith.

“I would say, sir, that it don’t seem right that a Scotchman should be able——” But there he stopped, aware no doubt that he was about to make a remark even blunter.

Keith could not help smiling. “I think, my friend, that we had better not pursue that subject. May I ask whether it is by a delicate attention of the authorities that you have been detailed to wait upon me?”

“No, sir; I only come to the fort yesterday, the corporal that was here before having gone off duty sick; and me not being capable of much at present with this foot, I was told off in his place.”

“Are the ordinary prisoners—the rebels, I mean—in your charge?”
