BREAKFAST passed off very pleasantly, and by the time it was over Serge was upon much better terms with the two Aerians than he had been on the previous day. He had taken Olga’s warning and appeal to heart, and he had done so all the more easily for the reason that he felt somewhat ashamed of himself for the ill-temper and bad manners of which he had been guilty, and which their two new acquaintances had repaid with such dignified courtesy and good humour.
His frankly-expressed apology was accepted with such perfect good nature, unmixed with even a suspicion of condescension, that he felt at ease with them at once, and even began to regret that his destiny made it impossible for him to be their friend instead of their enemy.
The discussion of their plans for the day occupied the rest of the meal. They had a whole twenty-four hours before them, for the Ithuriel would not be back from San Francisco, where she was going when she passed the train, until ten o’clock on the following morning, so it was arranged that they would begin the day with a sleigh drive—a luxury which not even Aeria could afford,—then the two Aerians were to see the sights of the city under the guidance of Olga and Serge, and perform the chief of the duties that brought them to St. Petersburg.
After luncheon they were to have a couple of hours on the[67] ice in the park, into which the Yusupoff Gardens of the nineteenth century had been expanded, after which they would see the ice palaces illuminated at dusk, then dine, and finish the day at the opera. When the air-ship arrived, a rapid flight was to be taken across Europe over the Alps and back to Moscow, across Italy, Greece, and the Black Sea, which would enable Alan and Alexis to deposit their guests with their Moscow friends soon after nightfall.
The sleigh drive took the form of a race, on the plain stretching towards Lake Ladoga, between the two troikas driven by Serge and Olga, who had so managed matters that she had Alan for a companion, and who, not a little to Serge’s disgust, won it, after a desperate struggle, by a head. The race was a revelation to the two Aerians, and when Alan handed Olga out of the sleigh after they had trotted quietly back to the city, the interest which she had excited in him during the railway journey had already begun to deepen into a sentiment much more pleasing and dangerous.
The rest of the morning was devoted to driving about the city, and to paying a visit to the ancient fortress of Peter and Paul, which alone of all the fortress prisons of Russia had been preserved intact as a fitting monument of fallen despotism and a warning to all future generations. Once at least in his life every man in Aeria visited this fortress, as good Moslems visit Mecca, and this was the duty which Alan and Alexis were now performing.
In one of the horrible dungeons deep down in the foundations of the fortress, under the waters of the Neva, they were shown a massive gold plate riveted on to the rough, damp, stone wall. Its surface was kept brightly polished, and it looked strangely incongruous with the gloom and squalor of the cell. On it stood an inscription in platinum letters let into the gold:
“In this cell Israel di Murska, afterwards known as Natas, the Master of the Terror, was imprisoned in the year 1881, previous to his exile to Siberia by order of Alexander Romanoff the last of the Tyrants of Russia.”
[68]
With feelings wide asunder as love and hate, or gratitude and revenge, the descendant of Natas and the daughter of the Romanoffs stood in front of this memorial plate, and read the simple and yet pregnant words. Alan and Alexis both bent their heads as if in reverence for a moment, but Olga and Serge gazed at it with heads erect and eyes glowing with the fires of anger, in a silence that was broken by Alan saying—
“Liberty surely never had a stranger temple than this, and yet this dungeon is to us what the Tomb of the Prophet is to the Moslems. I wonder what the Last of the Tsars would have thought if he could have foreseen even a little part of all that sprang from the tragedy that was begun in this dismal cell?”
“He would have killed him,” said Olga, carried away for the moment by an irrepressible burst of passion, “and then there would have been no Natas, no Terror, and no Terrorist air-fleet, and Alexander Romanoff would have died master of the world instead of a chained felon in Siberia! Your ancestor, Richard Arnold, would have starved in his garret, or killed himself in despair, as many other geniuses did before him, and”—
“And the world would have remained the slave-market of tyrants and the shambles of murderous men. Let us thank God that Natas lived to do his work!” said Alan in a tone of solemn reverence, wondering not a little at Olga’s strange outburst, and yet not having the remotest idea of its true cause.
Neither Olga nor Serge could reply to this speech. They would have bitten their tongues through rather than say “Amen” to it, and anything else they dare not have said. After a moment more of somewhat constrained silence, Olga turned towards the door and said—
“Come! Let us go, the air of this place poisons me!”
When they got on the ice after lunch, Olga was not a little astonished to find that, perfect as she and Serge were in skating, the two Aerians were little inferior to them, despite the fact that they had just left their tropical home for the first time.
“How is this?” said Olga to Alan, as, hand in hand, they went sweeping over the ice in long, easy curves. “I suppose you manufacture your ice for skating purposes in Aeria?”
[69]
“No,” he said. “Some of our mountains rise above the snow-line, and in their upper valleys they have little lakes, so, when we want a skating surface, we just pump the water up and flood them and let it freeze. Besides this—I don’t think there is any harm in my telling you that we have a sort of wheel-skate which runs quite as easily as steel does on ice.”
“Ah,” said Olga, possessed by a sudden thought. “Then I suppose that is why the streets of your splendid city are so broad, and white, and smooth?”
Quietly as the words were spoken, Alan’s hand tightened upon hers as he heard them with a grip that almost made her cry out with pain. It was some moments before he recovered from his astonishment sufficiently to ask her the meaning of her unexpected and amazing question. She greeted his question with a saucy smile and a mocking, upward glance, and said quietly—
“Simply because I have seen them!”
It was a bow drawn at a venture. She had suddenly determined to test the truth of her vision and hazard a description from it of the unknown land.
“You have seen them?” cried Alan, now more amazed than ever. “But, pardon me, even at the risk of contradicting you I must tell you that that is impossible. No one not a born Aerian has set eyes on Aeria for more than a hundred years.”
“So you think perhaps,” she said in the same quiet, half-mocking tone. “Well now, listen and tell me whether this description is entirely incorrect. If it is correct you need say nothing, if it is not you can tell me so.”
And then she began, while he listened in a silence of utter stupefaction, and described the valley and city of Aeria as she had seen them in her dream-vision. When she had finished he was silent for several moments, and then said in a voice that told her that she had really seen it as though with the eyes of flesh—
“What are you? A sorceress, or—No, you cannot be an Aerian girl in disguise, for none ever leaves the country till she is married.”
[70]
“Then as I cannot be the latter,” said Olga, “you must, I suppose, consider me the former. Now I shall take my revenge for your reticence in the train yesterday, and tell you no more. We are quits to that extent at least, and now we will go back to my brother, if you please.”
With this Alan was forced to be content. Indeed, he could not have pursued the subject without breaking his oath, and so a few minutes later it came about that Olga and Serge were skating together in an unfrequented part of the lake, and here Olga took an opportunity that she might not have again of telling him as much as she thought fit for him to know of her plans for capturing the air-ship on the following day.
“I needn’t tell you,” said she, “that this air-ship is worth everything to us, and that therefore we must be ready to go to any extremities to get possession of it. It is the first step to the command of the world, for you heard Alan say to-day that she is the swiftest vessel in the whole Aerian fleet.”
“But to do that we must first overcome the crew,” said Serge, looking anxiously about to see if there was anyone within earshot. “How are we going to do that—two of us against ten or a dozen, armed with powers we know nothing about?”
“We must find means to drug them—to poison them, if nece............
