AT Königsberg, which was reached in nine hours after leaving London, that is to say, soon after seven o’clock in the evening, the Eastern express divided: five of the cars went northward to St. Petersburg, carrying those passengers who were going to participate in the Winter Festival, while the other five which made up the train went on to Moscow and the East. During the twenty minutes’ stop at Berlin, Olga had found an opportunity of having a few words in private with Serge, and had succeeded in persuading him, much against his will, of the necessity of postponing their marriage, and therefore their visit to Moscow, for the execution of a daring and suddenly-conceived plan which she had thought out, but which she had then no time to explain to him. Serge, though very loath to postpone even for a day or two the consummation of his hopes and the hour which should make Olga irrevocably his, so far as human laws could bind her to him, was so far under the domination of her imperious will that, as soon as he saw that she had determined to have her own way, he yielded with the best grace he could. Olga chided him gently and yet earnestly for his outbreak of temper towards Alan, and told him plainly that, where such tremendous issues were concerned as those which were involved in the struggle which sooner or later they must wage with the Aerians, no personal considerations whatever could be permitted a moment’s serious thought. If she could sacrifice her own feelings, and disguise her hatred of the tyrants of the world under the mask of friendliness, for the sake of the ends to which both their lives were devoted, surely he, if he were at all worthy of her love, could so far trust her as to restrain the unreasoning jealousy of which he had already been guilty. Either, she told him, he must trust to her absolutely for the present, or he must take the management of affairs into his own hands; and, as she said in conclusion, he must find some influence stronger than hers in their dealings with him who would one day be the ruler of Aeria, and, therefore, the real master of the world, should it ever be possible to dispute the empire of Earth with the Aerians. From the influence which she exercised over himself, Serge knew only too well that he could not hope to rival her in this regard where a man was concerned, and so he perforce agreed to her proposal, and for the present left the conduct of affairs in her hands. A telephonic message was therefore sent from Königsberg to the friends who expected them at Vorobièvŏ, near Moscow, to tell them of the change in their plans; and when the train once more glided out over the frozen plains of the North, the four were once more seated together in the brilliantly-lighted car, which flashed like a meteor through the gathering darkness of the winter’s night.
