But we were not out of it yet. I make no doubt that no sooner was my back turned than the little rat in fustian, his mind set on a possible reward, was plucking at the lad’s sleeve with suggestions and doubts. In any case there came presently a knock at the door. I opened. The boy officer was there with a red face obstinately set.

“Sir, I must trouble you again,” he said icily. “You say you are Sir Robert Volney. I must ask you for proofs.”

At once I knew that I had overdone my part. It had been better to have dealt with this youth courteously; but since I had chosen my part, I must play it.

“Proofs,” I cried blackly. “Do you think I carry proofs of my identity for every country bumpkin to read? Sink me, ’tis an outrage.”

He flushed, but hung doggedly to his point.

“You gain nothing by insulting me, Sir Robert. I may be only a poor line officer and you one high in power, but by Heaven! I’m as good a man as you,” cried the boy; then rapped out, “I’ll see your papers, if you have me broke for it.”

My papers! An inspiration shot into my brain. When Volney had substituted for me at Portree he had given me a pass through the lines, made out in his name and signed by the Duke of Cumberland, in order that I might present it if challenged. Hitherto I had not been challenged, and indeed I had forgotten the existence of it, but now— I fished out the sheet of parchment and handed it to the officer. His eye ran over the passport, and he handed it back with a flushed face.

“I have to offer a thousand apologies for troubling you, Sir Robert. This paper establishes your identity beyond doubt.”

“Hope you’re quite satisfied,” I said with vast irony.

“Oh, just one more question. The lady travelling with you?”
