“You haf seen what you should not haf seen, redcoat!” he repeated fiercely. “Pefore you go away from thiss place you shall be swearing to keep silence!”

“That I certainly shall not swear to do,” replied Captain Windham promptly. “I am not accustomed to take an oath at any man’s bidding, least of all at a rebel’s.”

Again the dark flame shone in the Highlander’s eyes.

“And you think that we will pe letting you go, Sassenach?”

“I think that you will be extremely sorry for the consequences if you do not,” returned the soldier. “You know quite well that if you lay a finger upon me you will have to answer for it to your master or chief, or whatever he is!”

“We are the foster-brothers of Mac ’ic Ailein,” responded Lachlan slowly. (“What, all of you?” interjected Keith. “I wish him joy of you!”) “He knows that all we do iss done for him. If we should pe making a misstake, not knowing hiss will . . . or if you should fall by chance into the loch, we should pe sorry, but we could not help it that your foot should pe slipping, for it wass hurt yessterday . . . and you would nefer go back to Kilcumein to tell the saighdearan dearg what you haf peen seeing.”

He did not now seem to be threatening, but rather, with a kind of gloomy satisfaction, thinking out a plausible course of action with regard to the intruder, and it was a good deal more disquieting to the latter than his first attitude. So was the expression on the faces of the other men when Lachlan harangued them volubly in his own language. His brother Neil alone appeared to be making some remonstrance, but in the end was evidently convinced, and almost before the unlucky officer realised what was toward, the whole group had launched themselves upon him.

Keith Windham fought desperately, but he had no chance at all, having been surrounded and almost held from the outset, and in a moment he was borne down by sheer weight of numbers. Buttons came off his uniform, his wig was torn bodily from his head by some assailant who probably imagined that he had hold of the Sassenach’s own hair, he was buffeted and nearly strangled, and lay at last with his face pressed into the heather, one man kneeling upon his shoulders, while another tied his hands behind his back, and a third, situated upon his legs, secured his ankles. Outraged and breathless, the soldier had time for only two sensations: surprise that no dirk had yet been planted in him, and wonder whether they really meant to take him down and throw him into the lake.

The struggle had been conducted almost in silence; but conversation broke out again now that he was overpowered. Only for a moment, however; then, as suddenly, it ceased, and the heavy, bony knees on Captain Windham’s shoulder-blades unexpectedly removed themselves. A sort of awestruck silence succeeded. With faint thoughts of Druids and their sacrifices in his mind Keith wondered whether the patriarchal soothsayer were now approaching to drive a knife with due solemnity into his back . . . or, just possibly, to denounce his descendants’ violence. But he could not twist himself to look, for the man on his legs, though apparently smitten motionless, was still squatting there.

And then a voice that Keith knew, vibrating with passion, suddenly shouted words in Erse whose purport he could guess. The man on his legs arose precipitately. And next moment Ewen Cameron was kneeling beside him in the heather, bending over him, a hand on his shoulder. “Captain Windham, are you hurt? God forgive me, what have they been doing? Tied!” And in a moment he had snatched a little knife out of his stocking and was cutting Keith’s bonds. “Oh, why did I let you out of my sight! For God’s sake tell me that you are not injured!”
