According to the stipulations arranged between himself and the confidential agent of the American Government, the blockading flotilla of dynamite cruisers ought to have sailed from America as soon as the cypher message containing the news of the battle of Dover reached New York. The message had been duly sent viâ Queenstown and New York, and had been acknowledged in the usual way, but no definite reply had come to it, and a month had elapsed without the appearance of the promised squadron. The explanation of this will be readily guessed. The American end of the Queenstown cable had been reconnected with Washington, but it was under the absolute control of Tremayne, who permitted no one to use it save himself.

Other messages had been sent to which no reply had been received, and a swift French cruiser, which had been launched at Brest since the battle of Dover, had been dispatched across the Atlantic to discover the reason of this strange silence. She had gone, but she had never returned. The Atlantic highway appeared to be barred by some invisible force. No vessels came from the westward, and those which started from the east were never heard of again.

His Majesty had treated the summons of the President of the Federation with silent contempt, just as such a victorious autocrat might have been expected to do. True, he knew the terrific power wielded by the Terrorists through their aërial fleet, and he had an uncomfortable conviction, which refused to be entirely stifled, that in the days to come he would have to reckon with them and it.

But that a member of the Terrorist Brotherhood could by any possible means have placed himself at the head of any body of men sufficiently numerous or well-disciplined to make them a force to be seriously reckoned with in military warfare, his Majesty had never for a moment believed.

And, more than this, however disquieting might be the uncertainty due to the ominous silence on the other side of the Atlantic, and the non-arrival of the expected fleet, there stood the great and significant fact that the army of the League had been permitted, without molestation either from the Terrorists or the Federation in whose name they had presumed to declare war upon him, not only to destroy what remained of the British fleet, but to completely invest the very capital of Anglo-Saxondom itself.

All this had been done; the sacred soil of Britain itself had been violated by the invading hosts; the army of defence had been slowly, and at a tremendous sacrifice of life on both sides, forced back from line after line, and position after position, into the city itself; his batteries were raining their hail of shot and shell from the heights round London, and his aerostats were hurling ruin from the sky upon the crowded millions locked up in the beleaguered space; and yet the man who had presumed to tell him that the hour in which he set foot on British soil would be the last of his Empire, had done absolutely nothing to interrupt the march of conquest.

From this it will be seen that Alexander Romanoff was at least as completely in the dark as to the possible course of the events of the near future as was the King of England himself, shut up in his capital, and cut off from all communication from the rest of the world.

On the morning of the 29th of November there was held at the Prime Minister's rooms in Downing Street a Cabinet Council, presided over by the King in person. After the Council had remained for about an hour in earnest consultation, a stranger was admitted to the room in which they were sitting.

The reader would have recognised him in a moment as Maurice Colston, otherwise Alexis Mazanoff, for he was dressed almost exactly as he had been on that memorable night, just thirteen months before, when he made the acquaintance of Richard Arnold on the Thames Embankment.

Well-dressed, well-fed, and perfectly at ease, he entered the Council Chamber without any aggressive assumption, but still with the quiet confidence of a man who knows that he is practically master of the situation. How he had even got into London, beleaguered as it was on every side in such fashion that no one could get out of it without being seen and shot by the besiegers, was a mystery; but how he could have in his possession, as he had, a despatch dated thirty-six hours previously in New York was a still deeper mystery; and upon neither of these points did he make the slightest attempt to enlighten the members of the British Cabinet.
