It was the face of the woman whom, in that portion of his strange double life which had been free from the mysterious influence of Natas, he had loved with well-assured hope that she would one day rule his house and broad domains with him. She was now Lady Muriel Penarth, the daughter of Lord Marazion, a Cornish nobleman, whose estates abutted on those which belonged to Lord Alanmere as Baron Tremayne, of Tremayne, in the county of Cornwall, as the Peerage had it. Noble alike by lineage and nature, no fairer mistress could have been found for the lands of Tremayne and Alanmere, but—what seas of blood and flame now lay between him and the realisation of his love-ideal!

He must forsake his own, and become a revolutionary and an outcast from Society. He must draw the sword upon the world and his own race, and, armed with the most awful means of destruction that the wit of man had ever devised, he must fight his way through universal war to that peace which alone he could ask her to share with him. Still much could be done before he took the final step of severance which might be perpetual, and he would lose no time in doing it.

As soon as it was fairly light, he rose and took a long, rapid walk over the home park, and when he returned to breakfast at nine he had resolved to execute forthwith a deed of gift, transferring the whole of his vast property, which was unentailed and therefore entirely at his own disposal, to the woman who was to have shared it with him in a few months as his wife. If the Fates were kind, he would come back from the world-war and reclaim both the lands and their mistress, and if not he would have the satisfaction of knowing that his broad acres at least had a worthy mistress.

At breakfast he met Natas again, and during the meal one of his footmen entered, bringing the letters that had come by the morning post.

There were several letters for each of them, those for Natas being addressed to "Herr F. Niemand," and for some time they were both employed in looking through their correspondence. Suddenly Natas looked up, and said—

"When do you expect to hear that Arnold is off the south coast?"

"Almost any day now; in fact, within the week, if everything has gone right. Here is a letter from Johnston to say that the Lurline has arrived at Plymouth, and that a bright look-out is being kept for him. He will telegraph here and to the club in London as soon as the air-ship is sighted. Twenty-four hours will then see us on board the Ariel, or whichever of the ships he comes in."

"I hope the news will come soon, for Michael Roburoff, the President's brother, who has been in command of the American Section, cables to say that he sails from New York the day after to-morrow with detailed accounts. That means that he will come with full reports of what the Section has done and will be ready to do when the time comes, and also what the enemy are doing.

"He sails in the Aurania, and as the Atlantic routes are swarming with war-ships and torpedo-boats, she will probably have to run the gauntlet, and it is of the last importance that Michael and his reports reach us safely. It will therefore be necessary for the air-ship to meet the Aurania as soon as possible on her passage, and take him off her before any harm happens to him. If he and his reports fell into the hands of the enemy, there is no telling what might happen."

"As nearly as I can calculate," said Tremayne, "the air-ship should be sighted in three days from now, perhaps in two. It will take the Aurania over four days to cross the Atlantic, and so we ought to be able to meet her somewhere in mid-ocean if she is able to get so far without being overhauled. Unfortunately she is known to be a British ship and subsidised by the British Government, so there will be very little chance of her getting through under the American flag. Still she's about the fastest steamer afloat, and will take a lot of catching."
