The words of her husband—for Khalid was her husband now as well as her slave—brought a sudden flush to Olga’s face, and this was succeeded by an almost deathly pallor. She put up her hand to the broadened circlet of gold which concealed the terrible scar of the wound made by Alan’s bullet, and said almost in a whisper—

“You and I—yes, you and I may live. We will! But if we do we must save ourselves alone.”

And with that she left him abruptly and went to her own room with the plan of her last crime already shaped in her mind.

She was the only woman on board the Revenge. Her maid Anna had been left behind at Alexandria, a maniac driven mad by the universal terror. What of Boris and the twenty-five men who formed the air-ship’s crew? If they were permitted to survive to the time when there would be no law but might, she would be the one woman in the world—one woman, beautiful and almost defenceless, among those who, though now her servants, would then be ready to slay each other in the dispute as to which of them should be her master.

Such a thought in such a mind as hers could have but one outcome. When the hour for the midday meal arrived, she bade Boris invite the whole crew into the main saloon, saying that, as this might be the last meal that any of them would eat, they would take it together. Then, as though moved by some sudden gracious fancy, she filled for every man with her own hands a glass of the best and oldest wine that had been reserved for her own use.

Khalid, rigid Moslem as he was, refused it, and she only touched it with her lips, but the others drained their glasses and drank death at her hands, even as the Aerians had drunk it in the same fashion and at the same table seven years before.

But this time it was fated that her sin should find her out more quickly. Later on in the afternoon Boris, to his amazement and alarm, found every man of his crew succumbing to an irresistible drowsiness, and soon this began to affect himself. A terrible thought at once flashed into his ever-suspicious mind. Fighting against the stupor that was stealing over his senses, he took a deep draught of strong spirit.

This conquered the poison for a time and cleared his intellect sufficiently for him to see what his pitiless mistress had done, and then there rose up in his mind a desperate longing for vengeance on the murderess who had used him and his companions as long as they were useful and then poisoned them like so many rats.

He took out his pistol and examined it to see if it was charged, and then, with the poison and the spirit fighting in his brain for mastery, he made his way from the engine-room to the quarter-deck, where Olga and Khalid were standing, watching with strained, fascinated eyes and faces that looked livid and corpse-like in the unnatural light of the Fire-Cloud, the long tongues of many-coloured flame that were shooting like so many gigantic serpents down from the zenith, as though they would lick the life-blood out of the world that now lay panting for breath and paralysed with fear beneath them.
