When they reached the promenade along the Sound sh.o.r.e Oscarovitch pointed to a beautifully-shaped, three-masted, two-funnelled white yacht lying about five hundred yards out, and said:

"That is the _Grashna_, Miss Marmion. I hope you like the look of her."

"She is beautiful!" exclaimed Nitocris, recognising at once the vessel which had met the Russian destroyer on the early morning of the 7th.

"She almost looks as if she could fly."

"So she can in a sense," laughed the Prince. "Come now, here is the gig.

We will get on board, and you shall see her go through her paces."

Neither she nor her father were strangers to yachts, but when they mounted the bridge of the _Grashna_ and looked over her from stem to stern, they had to admit that they had never seen anything quite so daintily splendid. They had chosen their rooms, and Jenny was below unpacking. Although, of course, he had a captain on board, the Prince often sailed the yacht himself when he had guests on board. He had a genuine love for the beautiful craft, and he took an almost boyish delight in showing what she could do. She was a twelve-hundred-ton, triple-screw, turbine-driven boat, and, thanks to the s.p.a.ce-economy of the new system, her builders had been able to stow away fifteen thousand horse-power in her engine-room, and this when fully developed gave a speed in smooth water of thirty-five knots or a little over forty statute miles an hour.

The anchor was up almost as soon as they got on to the bridge, and Oscarovitch moved the pointer of the telegraph to "Ahead slow." The quartermaster in the oval wheel-house behind him moved the little wheel a few spokes to starboard, her mellow whistle tooted, and she glided in an outward curve through the other yachts and shipping, and gained the open water.

"Now," he said, turning to Nitocris, "we can begin to move. It is roughly thirty English miles to Elsinore. If you have never done any fast travelling at sea and would like to do some now, I can get you there in about three-quarters of an hour."

"What!" exclaimed the Professor, "thirty miles in forty-five minutes by sea! That is over forty miles an hour. A wonderful speed."

"Yes," he replied, almost tenderly; "but my beautiful _Grashna_ is a wonderful craft--at least, I think you will say so when you see what she can do. Now, if you will take advice, you and Miss Marmion will go into shelter, for it will begin to blow soon."

Behind the wheel-house was an observation room, as it would be called in the States, running nearly the whole length of the bridge, and fronted with thick plate gla.s.s. They went in, and Oscarovitch turned the pointer to half-speed. There was no increase in vibration, but the sh.o.r.e began to slip away behind them faster and faster, and the northern suburbs of Copenhagen rose ahead and fell astern as though they were part of a swiftly moving panorama. Then the pointer went down to full speed, and the Prince, after a word to the quartermaster, joined them in the bridge-house and closed the door.

"You will need all your eyes to see much of the sh.o.r.e now," he said; "I have given her her wings."

Nitocris felt a shudder in the carpeted floor. Looking ahead she saw the bow lift slightly. Then a smooth, green swathe of water curled up on either side. She looked aft, and saw a broad torrent of froth, foaming like a furious, rapid stream away from the stern. The houses and trees on the sh.o.r.e seemed to run into each other, and slide out of sight almost before the eye could rest upon them. The water alongside was merely a blue-green blur. Nitocris involuntarily held her breath as though she had been out on deck.

"It is wonderful, Prince!" she said, almost in a whisper. "That alleged express from Hamburg was nothing to this: and yet how steadily she moves in spite of the speed. I should have thought that it would have nearly shaken us to jelly."

"That is the turbines, dear," said her father, who was already wondering whether Oscarovitch was doing this just to show how hopeless any pursuit of such a vessel would be. "They are a marvellous means of applying steam power. Lieutenant Parsons is robbing the sea of one, at least, of its worst terrors."

"Yes," added the Prince, "we are travelling a little over forty miles an hour; and if you got that speed out of reciprocating engines you would scarcely be able to lie on the deck without holding on to something, yet here we are as comfortable as though we were standing in a drawing-room."

"You have given us a new experience to begin with," said Nitocris, thinking how nice it would be to take her wedding trip with Merrill in such a craft as this. "Why, look at the two sh.o.r.es coming together, Dad!"

"No, excuse me," said Oscarovitch, "we are only about half-way to the Gate of the Baltic yet. That land on the right is the island of Hvreen.

When we have pa.s.sed that you will soon see the heights of Elsinore and Helsingborg rising ahead. There are only about two and a half miles between Denmark and Sweden there."

"Oh yes, of course. I am forgetting my geography," laughed Nitocris, as the low, wooded patch of land came rushing towards them as though it were adrift on a fast-flowing stream. "Goodness, what a speed!"

"A very wonderful craft, Prince," added the Professor, as the island drifted past; "she quite inclines me towards a breach of the tenth commandment. Now that you have given us this taste of the delights of speed, I think that if I were a millionaire, I should try to build one to beat her."

"Exactly," laughed Oscarovitch. "It is marvellous this fascination of speed. Your poet, Henley, touched the pulse of the times when he wrote those splendid lines of his. But surely, Professor, _you_ would not have very much difficulty in leaving all far behind. A man to whom mathematical impossibilities are as easy as an addition sum ought to be able to realise the dream of the ages and solve the problem of aerial navigation."

He looked him straight in the eyes as he said this. He fully believed in the possibility of human flight, given the transcendent genius who could work out the equation of weight and power. Perhaps that genius might be with him now in the bridge-house. His vivid imagination was already picturing the lovely girl at his side crowned Empress of the Russias and the East, and himself in command of an aerial navy, beneath whose a.s.sault the armies and navies and fortresses of the rest of the world would be as so many toys to play with and destroy.

"If I could do that, and I do not think it would be so very difficult after all," said Franklin Marmion, returning his glance, "I would not do it. It would put too much power in the hands of a few men, and we have enough of that already. The owner of a fleet of aerial warships would be above all human law. He could terrorise the earth, and make mankind his slaves. Life would become unendurable under such conditions.

Commercialism, which only means slavery plus the liberty to starve, is bad enough, but it is at least possible. The other would be impossible.

There is no man quite honest enough to be trusted with such a power as that. I have worked the thing out, and it is perfectly feasible, but I burnt my designs and calculations."

"What!" exclaimed Oscarovitch, flushing in spite of his effort to keep the blood back from his face. "You have solved the problem, and won't make use of the greatest invention of all the ages! Surely, Professor, that is a little quixotic, is it not?"

"Who am I that I should bring a curse upon humanity, Prince?" he answered gravely. "Do you not kill each other fast enough now? No, the world is not fit for such a development yet. My results will remain my own until Tom Hood's ideal of good government has been realised."

"And what was that, Dad?" asked Nitocris, who had a double reason for being interested in the conversation. "If I ever knew it, I have forgotten it."

"Despotism, Niti--and an angel from heaven for the despot," he replied, with another look into the Prince's eyes which brought him to the conclusion that the sooner his presence on board the _Grashna_ was dispensed with the better for his plans. There was a sense of quiet mastery in Franklin Marmion's manner which made him uneasy.

"Ah! there is the famous fortress, is it not? the home of Hamlet and Ophelia and the Ghost!" she exclaimed, pointing ahead to where a grey-blue ma.s.s was rising out of the water. "Do you believe in ghosts, Prince?" she added suddenly, flashing a glance at him which seemed to pierce his brain like a ray of unearthly light.

"Ghosts? No, Miss Marmion. I'm afraid I am too hopelessly materialistic for that. I never saw or heard of an authentic ghost, and I do not propose to believe until I see."

"We have a ghost at 'The Wilderness,'--the wraith of a poor young lady who killed herself after some royal blackguard had abused his own hospitality. She often comes to visit me in my study," said the Professor, as though he were relating the most ordinary occurrence.

"Ah," smiled the Prince, "that is very interesting: but, of course, it would be in the power of a man like yourself to have experiences which are denied to ordinary mortals. Still, granted all that, I confess that I have often wondered whether or not I should be frightened if I really did see a ghost."

"Yes, I wonder?" murmured Nitocris, with a great deal more meaning than he had any idea of just then.

All three felt that the conversation was getting a little difficult, and they were not sorry when the rapid rising of the rock of Elsinore made it necessary for Oscarovitch to go out to the engine telegraph.

"His Highness doesn't believe in ghosts now," whispered Nitocris to her father, when the door shut behind him, "but I think he will before very long. I wonder what he is really going to do? I've half a mind to----"

"No, no, Niti," he said quickly; "keep this side of the Border till you really have to cross it. What on earth, literally, would happen if he came back and found me standing here alone?"

"Oh, of course I didn't mean it," she smiled. "It would be very poor sport to spoil both the comedy and the tragedy before the curtain goes up. I wonder if the drama will begin to-night? I shouldn't be surprised."

"Nor I," said the Professor, a trifle grimly. "I didn't at all like his looks when I was talking about the flying machine. The brute looked as if he were quite capable of locking me up and starving or torturing me until I gave him the secret. My word, I should like to see him try! I'd have him grovelling at my feet in five minutes."

The door opened and Oscarovitch came in. He took off the cap which had been pulled tight over his eyes, and said:

"Well, we have arrived! Almost exactly forty-five minutes. There is Elsinore, there is Kronborg, King Frederick's sixteenth-century castle, and there is Marienlyst, which is to Copenhagen what Brighton is to London, only, I must say, in a much more refined sense. Now what is your pleasure, Miss Marmion? We have still nearly two hours before lunch, so, if you would like an hour's stroll ash.o.r.e, the gig will be ready in a couple of minutes."

"Thank you, Prince," she said with a rewarding smile. "Dad, what do you think? It all looks very beautiful under this sun and sky."

"Which, of course, means that you want to go ash.o.r.e, Niti," said her father. "For my own part, I certainly should like a little walk on new ground. I have never been here before."

"Then, of course we will go," said Oscarovitch, opening the door and going to the telegraph.

The yacht came to a standstill in a few minutes, and the gig was waiting at the foot of the gangway ladder. They spent a very pleasant hour ash.o.r.e, and what they saw, you may read of in your Murray and Baedeker, wherefore there is no need to set it down here. When they came aboard again, lunch was almost ready, and the steward presented his master and the Professor with quite exceptional c.o.c.ktails in the smoking-room. Then they went and had a wash, and the mellow gong sounded.

I am not very fond of those descriptions in stories which read like extracts from an upholsterer's price-list, nor yet those accounts of meals that, after all, are only menus writ large, so it may suffice to say that the saloon of the _Grashna_ was an arrangement of sandal-wood panels, framed in thin silver filigree, and hung with exquisite little masterpieces in water-colour, and black and white, and crayon, mostly sea-scapes, with here and there a beautiful head with living eyes which followed you everywhere; that the rich yellow of the panels was enhanced by _portieres_ and curtains of deep golden-bronze silk, and that the domed ceiling was of pale, sky-blue enamel spangled with the constellations of the northern heavens, which at night lit up the whole saloon with a soft electric radiance. As for the lunch, it was as nearly perfect as the best-paid chef afloat could make it, after his master had asked him as a personal favour to do so.

They ran back quietly to Copenhagen at twenty knots, and Oscarovitch and the Professor went ash.o.r.e to send off a few telegrams, leaving Nitocris, for her own reasons, to make herself at home on the yacht. They returned in time to dress for dinner and enjoy a stroll on the broad upper deck, and watch the sunset over the town and the quickly-increasing sparkle of the myriad lights on sh.o.r.e and sea. When they came up after dinner, these lights were only represented by a luminous haze glimmering under the stars to the northward. The _Grashna_ was heading nearly due south at an easy speed towards the Baltic Islands.

Something told both Nitocris and her father that the decisive hour would come soon, and they were both prepared for its advent.
