pint mug of coffee. As he was eating a paper-boy came in and laid an Echo on the table at which he was sitting. He took it up mechanically, and ran his eye carelessly over the columns. He was in no humour to be interested by the tattle of an evening paper, but in a paragraph under the heading of Foreign News a once familiar name caught his eye, and he read the paragraph through. It ran as follows:—

Railway Outrage in Russia.

When the Berlin-Petersburg express stopped last night at Kovno, the first stop after passing the Russian frontier, a shocking discovery was made in the smoking compartment of the palace car which has been on the train for the last few months. Colonel Dornovitch, of the Imperial Police, who is understood to have been on his return journey from a secret mission to Paris, was found stabbed to the heart and quite dead. In the centre of the forehead were two short straight cuts in the form of a T reaching to the bone. Not long ago Colonel Dornovitch was instrumental in unearthing a formidable Nihilist conspiracy, in connection with which over fifty men and women of various social ranks were exiled for life to Siberia. The whole affair is wrapped in the deepest mystery, the only clue in the hands of the police being the fact that the cross cut on the forehead of the victim indicates that the crime is the work, not of the Nihilists proper, but of that unknown and mysterious society usually alluded to as the Terrorists, not one of whom has ever been seen save in his crimes. How the assassin managed to enter and leave the car unperceived while the train was going at full speed is an apparently insoluble riddle. Saving the victim and the attendants, the only passengers in the car who had not retired to rest were another officer in the Russian service and Lord Alanmere, who was travelling to St. Petersburg to resume, after leave of absence, the duties of the Secretaryship to the British Embassy, to which he was appointed some two years ago.

"Why, that must be the Lord Alanmere who was at Trinity in my time, or rather Viscount Tremayne, as he was then," mused Arnold, as he laid the paper down. "We were very good friends in those days. I wonder if he'd know me now, and lend me a ten-pound note to get me out of the infernal fix I'm in? I believe he would, for he was one of the few really good-hearted men I have so far met with.

"If he were in London I really think I should take courage from my desperation, and put my case before him and ask his help. However, he's not in London, and so it's no use wishing. Well, I feel more of a man for that shillingsworth of food and drink, and I'll go and wind up my dissipation with a pipe and a quiet think on the Embankment."

CHAPTER II.

AT WAR WITH SOCIETY.

When Richard Arnold reached the Embankment dusk had deepened into night, so far, at least, as nature was concerned. But in London in the beginning of the twentieth century there was but little night to speak of, save in the sense of a division of time. The date of the paper which contained the account of the tragedy on the Russian railway was September 3rd, 1903, and within the last ten years enormous progress had been made in electric lighting.

The ebb and flow in the Thames had at last been turned to account, and worked huge turbines which perpetually stored up electric power that was used not only for lighting, but for cooking in hotels and private houses, and for driving machinery. At all the great centres of traffic huge electric suns cast their rays far and wide along the streets, supplementing the light of the lesser lamps with which they were lined on each side.

The Embankment from Westminster to Blackfriars was bathed in a flood of soft white light from hundreds of great lamps running along both sides, and from the centre of each bridge a million candle-power sun cast rays upon the water that were continued in one unbroken stream of light from Chelsea to the Tower.

On the north side of the river the scene was one of brilliant and splendid opulence, that contrasted strongly with the half-lighted gloom of the murky wilderness of South London, dark and forbidding in its irredeemable ugliness.

From Blackfriars Arnold walked briskly towards Westminster, bitterly contrasting as he went the lavish display of wealth around him with the sordid and seemingly hopeless poverty of his own desperate condition.

He was the maker and possessor of a far greater marvel than anything that helped to make up this splendid scene, and yet the ragged tramps who were remorselessly moved on from one seat to another by the policemen as soon as they had settled themselves down for a rest and a doze, were hardly poorer than he was.

For nearly four hours he paced backwards and forwards, every now and then stopping to lean on the parapet, and once or twice to sit down, until the chill autumn wind pierced his scanty clothing, and compelled him to resume his walk in order to get warm again.

All the time he turned his miserable situation over and over again in his mind without avail. There seemed no way out of it; no way of obtaining the few pounds that would save him from homeless beggary and his splendid invention from being lost to him and the world, certainly for years, and perhaps for ever.

And then, as hour after hour went by, and still no cheering thought came, the misery of the present pressed closer and closer upon him. He dare not go home, for that would be to bring the inevitable disaster of the morrow nearer, and, besides, it was home no longer till the rent was paid. He had two shillings, and he owed at least twelve. He was also the maker of a machine for which the Tsar of Russia had made a standing offer of a million sterling. That million might have been his if he had possessed the money necessary to bring his invention under the notice of the great Autocrat.

That was the position he had turned over and over in his mind until its horrible contradictions maddened him. With a little money, riches and fame were his; without it he was a beggar in sight of starvation.

And yet he doubted whether, even in his present dire extremity, he could, had he had the chance, sell what might be made the most terrific engine of destruction ever thought of to the head and front of a despotism that he looked upon as the worst earthly enemy of mankind.

For the twentieth time he had paused in his weary walk to and fro to lean on the parapet close by Cleopatra's Needle. The Embankment was almost deserted now, save by the tramps and a few isolated wanderers like himself. For several minutes he looked out over the brightly glittering waters below him, wondering listlessly how long it would take him to drown if he dropped over, and whether he would be rescued before he was dead, and brought back to life, and prosecuted the next day for daring to try and leave the world save in the conventional and orthodox fashion.

Then his mind wandered back to the Tsar and his million, and he pictured to himself the awful part that a fleet of air-ships such as his would play in the general European war that people said could not now be put off for many months longer. As he thought of this the vision grew in distinctness, and he saw them hovering over armies and cities and fortresses, and raining irresistible death and destruction down upon them. The prospect appalled him, and he
