The Prince of India, left in the passage of the Castle with Sergius, was not displeased with the course the adventure appeared to be taking. In the first place, he felt no alarm for Lael; she might be uncomfortable in the quarter to which she had been conducted, but that was all, and it would not last long. The guardianship of the eunuch was in his view a guaranty of her personal safety. In the next place, acquaintance with the Princess might prove serviceable in the future. He believed Lael fitted for the highest rank; she was already educated beyond the requirements of the age for women; her beauty was indisputable; as a consequence, he had thought of her a light in the court; and not unpleasantly it occurred to him now that the fair Princess might carry keys for both the inner and outer doors of the royal residence.

Generally the affair which was of concern to Lael was an affair of absorbing interest to the Prince; in this instance, however, another theme offered itself for the moment a superior attraction.

The impression left by the young master of ceremonies in the reception at the landing was of a kind to arouse curiosity. His appearance, manner, speech and the homage paid him denoted exalted rank; while the confidence with which he spoke for Sultan Amurath was most remarkable. His acceptance of the terms presented by the Princess Irene was little short of downright treaty-making; and what common official dared carry assumption to such a height? Finally the Prince fell to thinking if there was any person the actual governor of the Castle would quietly permit to go masquerading in his authority and title.

Then everything pointed him to Prince Mahommed. The correspondence in age was perfect; the martial array seen galloping down the bank was a fitting escort for the heir-apparent of the gray Sultan; and he alone might with propriety speak for his father in a matter of state.

"A mistake cannot be serious," said the Prince to himself, at the end of the review. "I will proceed upon the theory that the young man is Prince Mahommed."

This was no sooner determined than the restless mind flew forward to an audience. The time and place—midnight in the lonesome old Castle—were propitious, and he was prepared for it.

Indeed it was the very purpose he had in view the night of the repast in his tent at El Zaribah where he so mysteriously intrusted the Emir Mirza with revelations concerning the doom of Constantinople.

Once more he ran over the scheme which had brought him from Cipango. If Islam could not be brought to lead in the project, Christendom might be more amenable to reason. The Moslem world was to be reached through the Kaliph whom he expected to find in Egypt; wherefore his contemplated trip down the Nile from Kash-Cush. If driven to the Christian, Constantine was to be his operator. Such in broadest generality was the plan of execution he had resolved upon.

But to these possibilities he had appended another of which it is now necessary to speak.

Enough has been given to apprise the reader of the things to which the Prince preferably devoted himself. These were international affairs, and transcendently war. If indeed the latter were not the object he had always specially in mind, it was the end to which his management usually conducted. For mere enjoyment in the sight of men facing the death which strangely passed him by, he delighted in hovering on the edge of battle until there was a crisis, and then plunging into its heated heart.
