The grand master was, however, too politic to betray any doubt of Georges' sincerity. Were he treated as a traitor, Paleologus might find another agent to do the work. It was, therefore, better to feign a belief in his story, to obtain all the information possible from him, and at the same time to prevent his gaining any knowledge of affairs that would be of the slightest use to the Turks. Instructions were therefore given to the two knights that, while Georges was to be treated with all courtesy, he was to be strictly watched, though in such a manner that he should be in ignorance of it, and that, whenever he turned his steps in the direction of those parts of the defences where fresh works had been recently added and preparations made of which it was desirable the Turks should be kept in ignorance, he was to be met, as if by accident, by one of the knights told off for the purpose, and his steps diverted in another direction. Georges soon made himself popular among many of the knights, who had no suspicions of his real character. He was a man of exceptional figure, tall, strong, splendidly proportioned, with a handsome face and gallant bearing. He was extremely well informed on all subjects, had travelled widely, had seen many adventures, was full of anecdote, and among the younger knights, therefore, he was soon regarded as a charming companion. His very popularity among them aided D'Aubusson's plans, as Georges was generally the centre of a group of listeners, and so had but few opportunities of getting away quietly to obtain the information he sought. Gervaise delivered his report to the grand master. “I am free now,” D'Aubusson said, “and will accompany you to St. Nicholas. I have been detained by the coming of this man Georges. He is a clever knave, and, I doubt not, has come as a spy. However, I have taken measures that he shall learn nothing that can harm us. No lives have been lost at the tower, I hope?” “No, sir; Caretto has forbidden any to show themselves on the walls.” “He has done well. This is no time for rash exposure, and where there is naught to be gained, it is a grave fault to run risks.” On arriving at the end of the mole, D'Aubusson, accompanied by Caretto, made an investigation of the effect of the Turks' fire. “'Tis worse than I expected,” he said. “When we laid out our fortifications the thought that such guns as these would be used against them never entered our minds. Against ordinary artillery the walls would stand a long battering; but it is clear that we shall have to depend more upon our swords than upon our walls for our defence. Fortunately, although the Turks have indeed chosen the spot where our walls are most open to the assaults of their battery, they have to cross the water to attack the breach when it is made, and will have to fight under heavy disadvantage.”
