Keith Windham coloured. “To bring back the memory of that day, sir, is to remind me that you then put me under a deep obligation, and to make my present task the more odious. But I must carry it out. Your sword, if you please!”

Ewen shrugged his shoulders in the way Miss Cameron condemned as outlandish. “I had no intention, sir, of reminding you of an obligation which I assure you I had never regarded as one. But why should I render your task, as you call it, more pleasant? And why make a task of it at all? The Prince, as you see, is not here, and Generals Guest and Preston will find me a very disappointing substitute.”

Keith Windham came nearer and dropped his voice. His face looked genuinely troubled. “I wish, Ardroy, for your own sake, that you would let me take you unharmed! Take you I must; you are a chieftain and the Prince’s aide-de-camp, as I happen to know. It is the fortune of war, as it was last August, when our positions were reversed. So, for the sake of the courtesy and hospitality which I then received from you——”

“My sorrow!” burst out Ewen. “Must my past good conduct, as you are pleased to consider it, lead to my undoing now? . . . And I very much doubt whether our positions are reversed, and whether any further disturbance—and you have made not a little already—do not bring the guard from the West Bow about your ears. If I might give advice in my turn, it would be to get back to the Castle while yet you can!”

“Thank you,” said Keith with extreme dryness; “we will. Sergeant, have your men secure the prisoner.”

He stood back a little. Ewen had already decided in the event of a fight to abandon his post by the writing-table, where, on one side at least, he could be taken in flank, and where any shifting of the table itself, highly probable in a struggle, would cause the panel to reveal its secret. (Not that that would greatly matter now.) Immediately the Englishman stepped back, therefore, he darted across the room and ensconced himself in the corner by the nearest window, hastily wrapping his cloak, which he had snatched up for the purpose, round his left arm. His eyes sparkled; he was going to have his fight!

“I am ready,” he remarked cheerfully, seeing the much slower preparations of his assailants. “Is it to be a charge with the bayonet, or are you going to use the butt, my friends?”

“You’ll not use either!” said Keith sharply to his men. “I do not wish this gentleman injured.”

“Then make him put up his sword, sir,” retorted the sergeant in justifiable indignation. “Else it’s ourselves will be injured, I’m thinking!”

Ewen was about to endorse this opinion when a familiar and most welcome sound came to him through the closed window behind him. No mistaking that strain; and that the soldiers should hear it too he turned a little and dashed his elbow, protected by the curtain, through the nearest pane of glass. In it flowed, wailing and menacing, the Cameron rant: ‘Sons of the dogs, come hither, come hither and you shall have flesh . . .’
