over-square and a white scar zigzagged across his cheek, but I liked the look of him none the less for that. His frank manly countenance wore the self-reliance of one who has lived among the hills and slept among the heather under countless stars. For dress he wore the English costume with the extra splash of colour that betokened the vanity of his race. “’Fore God, sir, you came none too soon,” he cried in his impetuous Gaelic way. “This riff-raff of your London town had knifed me in another gliff. I will be thinking that it would have gone ill with me but for your opportune arrival. I am much beholden to you, and if ever I can pay the debt do not fail to call on Don—er—James Brown.”

At the last words he fell to earth most precipitately, all the fervent ring dropping out of his voice. Now James Brown is a common name enough, but he happened to be the first of the name I had ever heard crying a Highland slogan in the streets of London, and I looked at him with something more than curiosity. I am a Scotchman myself on the mother’s side, so that I did not need to have a name put to his nationality.

There was the touch of a smile on my face when I asked him if he were hurt. He gave me the benefit of his full seventy three inches and told me no, that he would think shame of himself if he could not keep his head with his hands from a streetful of such scum. And might he know the name of the unknown friend who had come running out of the night to lend him an arm?

“Kenneth Montagu,” I told him, laughing at his enthusiasm.

“Well then, Mr. Kenneth Montagu, it’s the good friend you’ve been to me this night, and I’ll not be forgetting it.”

“When I find myself attacked by footpads I’ll just look up Mr. James Brown,” I told him dryly with intent to plague.

He took the name sourly, no doubt in an itching to blurt out that he was a Mac-something or other. To a Gaelic gentleman like him the Sassenach name he used for a convenience was gall and wormwood.

We walked down the street together, and where our ways parted near Arlington Street he gave me his hand.

“The lucky man am I at meeting you, Mr. Montagu, while we were having the bit splore down the street. I was just weanying for a lad handy with his blade, and the one I would be choosing out of all England came hot-foot round the corner.”

I made nothing of what I had done, but yet his Highland friendliness and flatteries were balm to a sick heart and we parted at my door with a great deal of good-will.

“Past ten o’clock, and a clear starry night!” the watch was bawling as I set out from my rooms to keep my appointment with Lord Balmerino. I had little doubt that a Stuart restoration was the cause for which he was recruiting, and all day I had balanced in my mind the pros and cons of such an attempt. I will never deny that the exiled race held for me a strong fascination. The Stuarts may have been weak, headstrong Kings in their prosperity, but they had the royal virtue of drawing men to them in their misfortune. They were never so well loved, nor so worthy of it, as when they lived in exile at St. Germains. Besides, though I had never mixed with politics, I was a Jacobite by inheritance. My father had fought for a restoration, and my uncle had died for it.

There were no fast bound ties to hold me back. Loyalty to the Hanoverians had no weight with me. I was a broken man, and save for my head could lose nothing by the venture. The danger of the enterprise was a merit in my eyes, for I was in the mood when a man will risk his all on an impulse.

And yet I hung back. After all an Englishman, be he never so desperate, does not fling away the scabbard without counting the cost. Young as I was I grued at the thought of the many lives that would be cut off ere their time, and in my heart I distrusted the Stuarts and doubted whether the game were worth the candle.

I walked slowly, for I was not yet due at the lodgings of Balmerino for an hour, and as I stood hesitating at a street corner a chaise sheered past me at a gallop. Through the coach window by the shine of the moon I caught one fleeting glimpse of a white frightened girl-face, and over the mouth was clapped a rough hand to stifle any cry she might give. I am no Don Quixote, but there never was a Montagu who waited for the cool second thought to crowd out the strong impulse of the moment. I made a dash at the step, missed my footing, and rolled over into the mud. When I got to my feet again the coach had stopped at the far end of the street. Two men were getting out of the carriage holding between them a slight struggling figure. For one instant the clear shrill cry of a woman was lifted into the night, then it was cut short abruptly by the clutch of a hand at the throat.

I scudded toward them, lugging at my sword as I ran, but while I was yet fifty yards away the door of the house opened and closed behind them. An instant, and the door reopened to let out one of the men, who slammed it behind him and entered the chaise. The postilion whipped up his horses and drove off. The door yielded nothing to my hand. Evidently it was locked and bolted. I cried out to open, and beat wildly upon the door with the hilt of my sword. Indeed, I quite lost my head, threatening, storming, and abusing. I might as well have called upon the marble busts at the Abbey to come forth, for inside there was the silence of the dead. Presently lights began to glimmer in windows along the dark street, and nightcapped heads were thrust out to learn what was ado. I called on them to join me in a rescue, but I found them not at all keen for the adventure. They took me for a drunken Mohawk or some madman escaped from custody.

“Here come the watch to take him away,” I heard one call across the street to another.

I began to realize that an attempt to force an entrance was futile. It would only end in an altercation with the approaching watch. Staid citizens were already pointing me out to them as a cause of the disturbance. For the moment I elected discretion and fled incontinent down the street from the guard.

But I was back before ten minutes were up, lurking in the shadows of opposite doorways, examining the house from front and rear, searching for some means of ingress to this mysterious dwelling. I do not know why the thing stuck in my mind. Perhaps some appealing quality of youth in the face and voice stirred in me the instinct for the championship of dames that is to be found in every man. At any rate I was grimly resolved not to depart without an explanation of the strange affair.

What no skill of mine could accomplish chance did for me. While I was inviting a crick in my neck from staring up at the row of unlighted windows above me, a man came out of the front door and stood looking up and down the street. Presently he spied me and beckoned. I was all dishevelled and one stain of mud from head to foot.

“D’ ye want to earn a shilling, fellow?” he called.

I grumbled that I was out of work and money. Was it likely I would refuse such a chance? And what was it he
