“Now, we shall meet our enemies at breakfast, and I want you to be a great deal more cordial and friendly than you were yesterday. Our own feelings concern ourselves alone, but in our outward conduct we owe something to the sacred cause which we both have at heart. You can imagine how great a sacrifice I am making in my relations with those whom I have been taught to hate from my cradle.

“I can see as well as you do, perhaps better, that this future ruler of Aeria admires me in his own boyish way. If I can bring myself to appear complaisant, surely it is not too much to ask you to look upon it with indifference, or even with interest,—a brotherly interest, you know; for you must remember that he knows me only as your sister.

“Now, I want you to ask them to come and have breakfast with us at our table, and to exert yourself to appear agreeable to them, even as I shall; and above all things, promise me that you will fall in with any suggestions that I may make as regards our trip in this wonderful air-ship which we are to make to-morrow.

“There is no time now to explain to you what I mean, but I swear to you, by the blood that flows in both our veins, that if I can only carry through, without any let or hindrance, the plans that I have already formed—that before forty-eight hours have passed that air-ship shall no longer be under Alan Arnoldson’s command.”

He looked at her for a moment with almost incredulous admiration. She returned his inquiring glance with a steady, unwavering gaze, which made suspicion impossible. All his life he had grown up to look upon her as sharing with him the one hope that was left of restoring the ancient fortunes of their family. More than this they had been lovers ever since either of them knew the meaning of love.

How then could he have dreamt that behind so fair an appearance lay as dark and treacherous a design as the brain of an ambitious woman had ever conceived? Intoxicated by her beauty and the memory of his lifelong love, he took a couple of steps towards her, took her unresisting into his arms again, and said passionately—

“Give me another kiss, darling, and on your lips I will swear to trust you always and do your bidding even to the death.”

She returned his kiss with a passion so admirably simulated that his resolve was thrice strengthened by it, and then she released herself gently from his embrace, saying—

“Even so, unto the death if needs be,—as I shall serve our sacred cause to the end, cost what it may! Come, it is time that we went down to breakfast.”
