“What a plague ails you, Captain Cameron, standing there like a grenadier! Sit down, man, and do not so insult our hostess’s excellent vintage.”

“I had rather, with Your Highness’s and Lady Easterhall’s leave,” replied Captain Cameron, “post myself in some part of the house whence I can get a view of the approach to it. Does not the close run up towards the Castle Hill, madam?”

“You are very nervous, sir,” commented O’Sullivan, half-sneeringly. “Why should the nearness of the Castle trouble Lady Easterhall, since his Royal Highness’s presence cannot possibly be known there? And of what use is the guard at the Weighhouse—your own clansmen, too—if they cannot prevent the garrison from coming out?”

But Lady Easterhall herself seemed of Ewen’s opinion. “The young gentleman is verra richt,” she declared. “He shall keep watch if he’s minded tae, though, as ye say, sir, the Castle’s little likely to trouble my hoose. Isobel, gang ye with Captain Cameron and show him the best windy for the purpose. Though even if they should send a picket here,” she added smiling, “His Royal Highness and all could be oot of the hoose before they could win entrance. There’s a secret stair, gentlemen, leads frae this verra room doun under the hoose to a bit door in the West Bow, and the entry to’t lies ahint yon screwtore at the side of the chimley, sae ye may be easy.”

All eyes turned towards the spot indicated, where, not far from the hearth, an ebony writing-table with inlay of metal and tortoiseshell—evidently a French importation—stood against the panelling. “A secret stair!” exclaimed the Prince, and, in a lower tone, “ma foi, rumour was right!—You hear, Ardroy? So now you need not deprive us of your society . . . nor of Miss Cochran’s.”

“Miss Cochran’s I need not in any case take from your Royal Highness,” responded Ewen, preparing to leave the room, “for I doubt not I can find a suitable look out without troubling her. But, even with the secret stair, I think it would be better to post a sentry.” A laugh from O’Sullivan followed him as he closed the door, and stirred his simmering wrath against the Quartermaster-General and Strickland to a still higher temperature. That they should without remonstrance allow the Prince to remain here, under the very shadow of the Castle, for no more valid object than to drink Lady Easterhall’s claret—and, of course, to give her pleasure by the honour done to her—was monstrous! It was true that it needed a certain amount of skill and courage to make a dash from the Castle, on account of the Highland guards in its neighbourhood, but it was dark, and he was still uneasy about the man who had passed them in the close.

The landing and stairway were ill lit, and he hesitated; he had better summon Saunders, perhaps. Then the door behind him opened and shut, a rather timid voice said, “Captain Cameron!” and turning, he beheld Miss Isobel Cochran with a lighted candle in her hand.

“I came, sir, because I thought you would need this.” She held it out none too steadily. “Oh, sir, you are the only one right of all of us! The Prince should not bide longer; it is too dangerous.”

“So I think,” said Ewen, looking down at her gravely. “I thank you, Miss Cochran.” He took the light from her. “Could you not persuade Lady Easterhall to hasten his departure?”

“Hardly,” answered the girl regretfully. “You can see what it means to her to have the Prince under her roof. . . . If you will go along that passage, sir, you will find a window out of which you can see some way up the close. . . . Stay, I will show you, since I am here.”
