The Duke and Simon were walking in the great open courtyards that lie between the many buildings within the Kremlin walls.

It was the Duke’s quizzical sense of humour that had prompted him to choose this particular spot — the very heart and brain of Soviet Russia — in which to hold a conference, having for its end a conspiracy against the Soviet State.

When a tired but cheerful Simon had pushed a slip of paper across the breakfast table that morning, bearing the one word “Tobolsk”, he had only nodded and said: “Let us go and see the Kremlin this morning.”

“Tobolsk,” said the Duke as they strolled through the first courtyard, “is on the other side of the Ural mountains.”

“Yes,” Simon agreed, dismally. “Sounds an awfully long way away.”

“It is about thirteen hundred miles, that is to say, a little less than the distance from here to London.”

Simon groaned. “Somewhere in Siberia, isn’t it?”

“It is, my friend —” De Richleau smiled. “But Siberia is a large place — let us be thankful that poor Rex is not imprisoned at Tomsk, which is two thousand — or Irkutsk, which is three thousand — or Yakutsk, which is four thousand miles away! All of these are in Siberia!”

“Well, I’m glad about that!” Simon gave his jerky little laugh into the palm of his hand. “But how do we get there?”

De Richleau looked round carefully, to make sure that they could not be overheard. “I spent some little time,” he said, slowly, “before we left the hotel, examining the maps and time-tables that are provided. Tobolsk is unfortunately not on the main Trans-Siberian line — it lies about a hundred and twenty miles to the north of the railway; there is, I find, a local line from the little town of Tyumen, which is just on the border of Siberia and Russia proper, but the main-line trains do not halt there. There is another local line running back northwestward from Omsk, but that would mean going a further four hundred miles into Siberia to get to Omsk, and the loss of at least a day.”

“Seems a difficult place to get at!” Simon interjected.

“It is. I think that the best way would be by the Trans-Siberian to Sverdlovsk, or Ekaterinberg, as it used to be called, after the amorous Empress of that name! That is the last town of any importance in European Russia, and all the main-line trains stop there. From there we could take the Trans-Siberian branch-line which heads direct for Tobolsk, but which is not yet quite completed. It comes to an end at the west bank of the Tavda River, but, there is only a hundred miles between Tavda and Tobolsk, and it is almost certain that there will be a service of sleighs between the dead end of the railway and the town.”

“You — er — couldn’t find out definitely?”

“No, nothing at all about the unfinished branch from Sverdlovsk or the branch-line from Tyumen, and furthermore we must be very careful in our inquiries not to arouse suspicions that we have any idea of venturing outside the prescribed limits for tourists.”

“I — er — suppose —” Simon hesitated, “the American Embassy couldn’t do anything?”

The Duke laughed. “How can they, my dear fellow; their position today is the same as yesterday. If we had actual proof that Rex was at Tobolsk it would be a different matter, but to charge the Soviet with holding him there on the information given you by Valeria Petrovna would only provoke another denial. They would move him at once to another prison. The only way is to go there and find out the truth — the problem is how to get there. Personally I favour the plan of going to Sverdlovsk and then trusting to chance.”

“Wonder if they’ll let us?” said Simon, doubtfully. “I haven’t seen anything about it in the booklets that they issue.”

“That we must find out, but, in any case, they will not prevent me taking a ticket through to Vladivostok, and as all the trains stop at Sverdlovsk, I can drop off there. I think I should tell you, my friend, that it is not my intention that you should accompany me on this journey.”

“Oh! Why?” Simon’s eyes flickered towards his friend.

“There are a variety of reasons,” said De Richleau, quietly. “You are, I think, very happily engaged here, in Moscow — it would be a pity to curtail your visit. It was by your quick wit that we discovered Jack Straw, which, in turn, supplied us with the reason for Rex’s visit to Russia. It is you, again, who have discovered his whereabouts — whereas, so far, I have done nothing. It is my turn now. When I step off the train at Sverdlovsk, I shall, I think, be outside the law; it would be a great comfort to me to have you here in Moscow, safe and free, and able, if I do not return in a short time, to stir up the Embassies on my behalf. It would be sheer foolishness for both of us to run our heads into the noose.”

“Um — I agree,” said Simon quickly, “very silly. It’s a good thing that you know the people at the Embassies too — you’ll have much more pull than I should. Obviously, you stay here, and I go to Tobolsk!”

“But, my friend — do not be foolish!” De Richleau frowned.

“I’m not.” Simon gave his jerky little laugh. “Now I’ll tell you. I didn’t get that information about Rex for nothing. Valeria Petrovna got it from Leshkin, but he made her promise that I should be out of Moscow by tonight, so that settled it!”

“Indeed!” said the Duke, with surprise. “But, even so, I fear it does not solve our problem. How will you manage in Tobolsk? You can speak no Russian!”

“Um!” Simon was a little dashed. “That’s a bit awkward!”

“We will both go,” said the Duke, with decision, “and I will confess that I shall be more glad to have you with me.”

“Well, to tell you the truth, I should simply hate to go alone.”

“That is settled then! Let us go to the head office of the Intourist. We will talk about a change of plans, and that we should like to go into Siberia. We will not talk of Tobolsk, but of Irkutsk — that is some fifteen hundred miles farther on; it is quite natural that we should wish to see it, as it is a wonderful city in the very heart of Siberia, near Lake Baikal, just north of the Mongolian Plain. It is there that all the political exiles used to make their homes before the Revolution. It was a centre of enlightenment and culture.

“I thought they were sent to the North,” said Simon. “To the Salt Mines and all sorts of terrible things.”

De Richleau shook his head. “Dear me, no, that is quite a mistaken idea; certain of the convicts — real felons and dangerous criminals — were, it is true, sent to the mines, but the politicals were only banished to the other side of the Urals, where they were free to trade and carry on their professions, moving from town to town, or settling in pleasant communities with similar aspirations to their own.”

When they arrived at the Bureau of the Intourist the Duke announced their plans. The lean, shrewd-eyed man who interviewed them was not particularly helpful. “Irkutsk? Yes, it was possible to go there — but there were many more interesting towns in Russia itself — Leningrad, now?”

“No,” the Duke truthfully replied. He had just come from Leningrad.

“Well then, Kiev, Odessa, Karkoff, Stalingrad?”

No, De Richleau and his friend thought of seeing all those wonderful places on their return — they had ample time — but above all things at present they desired to see Irkutsk!

Well, since they wished it, it could be done. The lean man proceeded to make out the tickets. Did they wish to leave tonight, Thursday, or on Sunday — or would they wait till Tuesday? The service ran thrice weekly. Tonight? Just as they wished. The train left the Smolenski Station at fifteen hours thirty, and the Saverinii at seventeen fifty-five. They would motor to the Saverinii? True it was a big difference; there was over an hour’s wait there, to take on mails, but they were advised to be there at least three-quarters of an hour before the time of departure — passports would have to be examined and luggage registered. He would have the tickets endorsed by the authorities and sent to their hotel.

“Do there happen to be any places of interest that we can see upon our way?” the Duke inquired in seeming innocence. “Do we go through Niji-Novgorod?”

The man shook his head. “No, you pass far to the north of Niji, going via Danilov, Bui, Viatka, Perm, Sverdlovsk, Omsk, Krasnoyarsk and Kansk.”

“What of Perm — that is a fine town, is it not?”

“Yes, you could break your journey there if you wish.”

“And Omsk — that again is a great town?”

“Yes, there also you could stop — but there is not much to see in these places.”

“And Tobolsk — do we stop at Tobolsk?”

“No, that is not on the Trans-Siberian line.”

“Ah, what a pity.” De Richleau’s face took on a rueful look. “Always, since I was a little boy, I have wanted to go to Tobolsk — it is, I think, the romance of the name. Is there no place at which we can change trains to go there? I should so greatly like to spend just one day in Tobolsk!”

The man looked away, impatiently. “It is impossible — a long, uncomfortable journey. Besides, it is a wild place — not fit for foreigners, and the Soviet Government considers itself responsible for all travellers who are its guests.”

“Dear me, how sad,” said the Duke, politely. “We will then go to Irkutsk and perhaps break our journey at Omsk and Perm on our way back.”

After they had left the Intourist Bureau, Simon asked, softly: “Why didn’t you take tickets to Sverlovsk or Ekaterinburg, or whatever it’s called — that’s really as far as we want to go!”

“Because, my friend, there would most certainly have been one of these eternal guides to meet us there if we had. Even if we had managed to evade his attentions the alarm would have been given at once. We arrive at Sverdloysk at 7.43 on Saturday morning. That is roughly a day-and-a-half’s journey — the train does not get to Irkutsk till midday on Tuesday — that is more than three days later. If we are fortunate the hue and cry will not begin until the guide who is detailed to meet us at Irkutsk finds that we are not on the train.”

“What about the officials on the train?” demanded Simon.

“True — that is a difficulty to be faced, but if we can overcome it we should gain three days’ grace, and much can be done in three days. But let us not talk here, we will go down to the bank of the river where there are fewer people.”

They walked for some time in silence, and when they reached the unfrequented embankment under the walls of the Kremlin, the Duke continued: “Now, we must make plans seriously. You realize of course that we shall have to leave the bulk of our baggage behind?”

Simon thought ruefully of his beautifully fitted dressing-case. “I suppose they’ll pinch that when they find out?”

“No.” The Duke’s eyes twinkled. “We can defeat them there. We shall take one suitcase each, and that only for show. The rest of our luggage we will deposit this afternoon at the Legation that you know of, then, if we get out of this wretched country, it can be returned to us through the diplomatic bag!”

“Well,” Simon grinned, much relieved, “I’m glad about that. I should have hated to see Leshkin with my dressing-case!”

“We shall have to get knapsacks,” the Duke continued, “to hold all that is essential, and abandon our suitcases when we leave the train.”

“Where do we get the knapsacks from?”

“There are several places in the Kitaigorod where we can get them — that is the old town, where the narrow streets are; many people think it is the Chinatown of Moscow because ‘Kitai’ is China in Russian, but actually it is an old Tartar word meaning Bastion — referring to the walls.”

“And then?”

The next thing is supplies. Luckily I brought certain things in case of such an emergency. We will buy some chocolate here, also some smoked ham and biscuits. Are you having a farewell luncheon with your lovely lady?”

“No, got all that over last night — thought it best.”

“And you were right,” the Duke agreed. Then, suddenly, but very low: “Hush! I think our wall-eyed friend is behind us again.”

Simon allowed a minute to elapse and then glanced round casually; sure enough, it was the same wizened little man. Today he was dressed in the slovenly uniform of a Red Guard, but they knew his face too well to mistake him. They quickened their pace, and in the turning and twisting of the narrow streets, succeeded in shaking him off before they reached the Kitaigorod.

By the time that they got back to the hotel they found that the tickets had been delivered, duly endorsed for Irkutsk. In the afternoon they packed and deposited their luggage with the ever-obliging Señor Rosas. Five o’clock found them standing on the Saverinii Station platform, two suitcases beside them — the principal contents of which were food and the knapsacks into which it was to be transferred at Sverdlovsk.

They found their compartment on the train without difficulty. Being of the “Direct Communication, 1st Category”, it contained two berths only and a private toilette, and, owing to the wide gauge of the Russian railways, when the berths were stowed away it made a large, comfortable coupé.

Punctually at seventeen hours fifty-five, the long train with its powerful engine began, almost imperceptibly, to move, and gradually gathering speed, started on its long, eleven-day journey to Vladivostok at the other end of Asia.

They settled themselves comfortably on the wide seats, and the Duke took out Norman Douglas’s South Wind, which he was reading for the fourth time. The sophisticated humour of the book never failed to amuse him. Simon gazed out into the swiftly moving darkness and thought a little wistfully of these last unforgettable days in Moscow, and the loveliness of the smiling eyes of Valeria Petrovna. He found difficulty in realizing that it was really Simon Aron who was even now speeding towards unknown adventures. His heart gave a little bump as he thought of what might lie before them — rescue, hardship by cold and hunger, flight for life, perhaps, and a little smile curved his lips as he found himself humming a tune. It was: “Malbrouck s’en vat en guerre!”

They dined better in the restaurant car than they had in the hotel, and Simon, at least, was grateful for an early bed.

When they awoke next day they had left Bui far behind and were crossing a seemingly interminable plain. Simon started to get up, but the Duke forbade him.

“You are ill, my friend,” he said, quickly.

“Ner,” said Simon.

“But yes,” said the Duke. “You are feverish!”

“Never felt better in my life,” said Simon.

‘That is a pity, since I’m afraid you’ve got to pass the day in bed!”

Simon grinned understandingly. He knew De Richleau to be a wily man, and felt certain that this was a part of some scheme which the Duke had hatched in the night to get them safely off the train at Sverlovsk.

When the train steward arrived with the news that breakfast was ready, De Richleau held a long conversation with him in Russian. He was a fat, jolly man, and seemed much concerned. Simon groaned and made himself look as ill as possible, but later he supplemented the weak tea and toast which the sympathetic steward brought him, with several rolls that the Duke had smuggled out of the restaurant car.

All that morning they rolled through the unending plain, until at a little after half past one they came to a halt at Viatka, where the Duke got out to stretch his legs. Simon, of course, had to remain in bed, and his luncheon was perforce meagre.

The scenery in the afternoon was more varied; they ran for many miles through the valley of the Chepsa River, but the early winter’s dusk had blotted out the landscape by four in the afternoon. It was quite late at night when the train snorted into Perm, but another consultation had been held by De Richleau and the jolly steward earlier in the evening, and certain drugs were procured during the halt, so the drowsy Simon found himself compelled to sit up and pretend to swallow capsules as the train steamed out. The Duke also took his temperature with great gravity in front of the now solemn and anxious steward.

This second night the train laboured and puffed its way through the Urals, but in the black darkness they could see nothing of the scenery. At a little after six the Duke woke Simon and said, with his grey eyes twinkling: “My poor friend — you are very, very ill I fear — dying almost, I think.”

Simon groaned, in truth this time, but De Richleau put on his dressing-gown and fetched the steward. “My friend,” he cried in Russian. “He will die — he is almost already dead!”

“What can we do,” said the fat steward, sympathetically shrugging his broad shoulders.

“We must get off at Sverdlovsk,” said the Duke.

“You cannot,” said the man. “Your tickets are marked for Irkutsk!”

“What does that matter,” protested the Duke, “the only hope for him is hospital.”

The man shook his head. “The station authorities — they will not permit.”

“It is three more days to Irkutsk,” said De Richleau, almost weeping. “You cannot let him die on the train!”

“No, no, he cannot die on the train!” agreed the steward, obviously frightened and superstitious. “It might mean an accident!”

“Then we must get off at Sverdlovsk!”

“You must see the officials, then — it is the only way.”

“Bah! the Tchinovinks!” De Richleau cried. “The officials, what use are they? All your life you have lived under the Tchinovinks, and what have they done for you? Tsarist or Bolshevist — they are all the same — delay, delay, delay, and in the meantime my poor friend dies. It must not be!”

“No, it must not be —” echoed the steward, fired by the Duke’s harangue. “The Tchinovinks are either rogues or fools. I have it! Always before we arrive at Sverdlovsk we draw into the goods-yard. You shall descend there!”

“Is it possible?” exclaimed the Duke.

“But yes, it shall be done!”

“My brother!” cried De Richleau, flinging his arms round the fat man’s neck!

“Little father!” exclaimed the steward, using in his emotion an expression that must have been foreign to his lips for many years.

“Come, let us dress him,” said the Duke, and without warning Simon found himself seized; he played up gallantly, letting his head loll helplessly from side to side, and groaning a little. It was a longish job, but at last they had him dressed and propped up in a corner.

De Richleau packed for both of them — gathering their few belongings together in the two suitcases the steward had left them.

They jogged on for a while through the grey light of the coming dawn, and at last, after a series of shrill whistles, the train came to a standstill; the steward returned, and with breathless mutterings in Russian, helped the Duke to get the apparently comatose Simon out of the compartment and along the corridor, then down the steps at the end of the carriage. He pushed their bags out after them, and, recognizing in the half light the high value of the banknote which De Richleau thrust into his hand, broke into voluble protestations of gratitude.

The Duke looked quickly about him; the dark masses of buildings seen indistinctly, and the glimmer of lights a few hundred yards ahead, was evidently the main station. They stood in the snow. About them were timber stacks, coal dumps, and immediately in their rear some rough sheds. With a snort the train moved slowly on — the steward still leaning from the window. As it gathered speed and disappeared into the gloom, De Richleau ceased to pretend that he was supporting Simon.

“Come,” he said. “This way — quickly!” and seizing one of the bags he headed for the cover of the sheds. Simon gripped the other and followed. They were not more than half way across the yard when Simon’s quick ear caught a crunching sound, as of someone stumbling suddenly over cinders. He whipped round, just in time to see in the semi-darkness a figure that had evidently leapt off the last coach of the train, scuttle behind one of the stacks of timber.

“We’re spotted,” he gasped.

“No matter. Leave this to me,” said the Duke, as he darted behind the shed. “Here, take this,” and he thrust the other suitcase into Simon’s free hand.

Simon stood, helpless and gaping, the two heavy bags, one in each hand, weighing him down. De Richleau flattened himself against the side of the shed — they waited breathlessly.

A soft, padding sound came to their ears, as of someone running on the thick carpet of snow, a second later a small man came round the corner full upon them. He made a rapid motion of recoil, but it was too late, the Duke’s left hand shot out and caught him by the throat. The small man did not utter a sound — he stared with terrified, bulging eyes over De Richleau’s shoulder, full at Simon, who saw at once that in his left eye there was a cast!

Then there happened a thing which shocked and horrified the mild, peace-loving soul of Simon Aron, for he had never witnessed such a thing before. With almost incredible swiftness the Duke’s right hand left the pocket of his greatcoat — it flew back to the utmost stretch of his shoulder, holding a long, thin, glittering blade — and then, with a dull thud, it hit the little man in the side, just under the heart. His eyes seemed for a second to start out of their sockets at Simon — then his head fell forward, and he dropped limp and soundless at De Richleau’s feet.

“Good God!” said Simon, in a breathless whisper, utterly aghast. “You’ve killed him.”

The Duke gave a grim laugh as he spurned the body with his foot. “What else was there to do, my friend — it was either him or us. We are in Soviet Russia, and when we stepped off that train, we placed ourselves beyond the pale!”
