Gerald felt like one in a dream. His adventure had been such a strange one, events had followed one another so quickly, the change from fear and almost despair to hope and safety had come so unexpectedly, that he had scarcely had time to realise all that was going forward. And then the stately magnificence of the scene at which he had been present, the sudden revelation of the personality of the being he had rescued—all these things, crowding into the short space of a single night, made his brain reel.

For some time he remained alone, turning these things over and over in his mind. He almost doubted the evidence of his own senses, and began vaguely to wonder whether it could all be real, or whether he had fallen asleep and was dreaming some extraordinary, fantastic dream.

After what seemed a long time, the door opened, and some one entered behind him; some one who, even before Gerald caught sight of him, was adding to the confusion of his ideas by speaking to him in English! Turning round sharply, he found himself face to face with a tall, good-looking man with a shrewd, intellectual face, who was regarding him with a smile which seemed to be half-kindly, half-amused. He was dressed like some of the principal officers he had seen; but there was that in his manner and general appearance which, apart from his speech, seemed to tell Gerald that he was one of his own race.

'Well, young sir, will you tell me your name?' was the query which came to Gerald's consciousness after a moment or two of bewilderment.

'My name is Gerald Wilton,' he said simply.

'And how did you come into these parts? Parents live round here?'

Gerald shook his head. 'I have none,' he answered sadly. 'I have a guardian, who is at present living on the island, however. His name is Armeath—Mr Marcus Armeath.'

The stranger uttered a long whistle, then he exclaimed, 'So, so! Marcus Armeath living on this island! I knew him some years ago. He was then in England engaged in some experiments, trying to discover—— But never mind that now.'

He broke off abruptly, and regarded Gerald again with his enigmatic smile, which, however, now seemed to have in it more of friendly interest. Then he took to pacing up and down the room, his hands behind him, as though lost in thought.

'Young sir,' said he presently, 'I don't know what star you were born under, but it seems perfectly clear that you are marked out for some experiences such as scarcely any one else on this Earth can boast of. You are in possession of a great secret, which we wished to keep to ourselves; and, further, it has been ordained that you should save the life of—of—well, of one who is never ungrateful to those who do him even the smallest service. He is my most gracious master, and he will talk with you himself later on; but, meanwhile, he has deputed me to see you, and prepare your mind for some tremendous facts which you might otherwise find it difficult to grasp all at once. I am instructed to tell you certain things which must appear to you so incredible, so impossible, that I doubt if you will believe them without further proof.'
