"I see something, Master Edgar. See--where that clump of reeds shows a foot above the water against the walls--the bottom must be near the surface there." "Maybe--unless there be but soft mud. Look again, Peter--we must, if we can, find a place where we can swing our rope full freely." Before the circuit of the walls had been completed, a place had been found where a low bank lay between the moat and the foot of the wall. This was hailed with satisfaction as a step in the direction of scaling the outer defences of the castle, and during the remainder of the day Edgar and Peter sat down to watch all that went on, and particularly what sentries were posted and how far their observation extended. Ere the day was out they had made up their minds that a good watch was kept, and that the slackness referred to by the priest had either never existed or had recently, from one cause or another, been entirely removed. Two men-at-arms were always upon the walls, keeping watch from opposite angles, from which the whole extent of the outer defences could be easily surveyed. Another man was posted at the gateway, to operate the drawbridge and to keep a lookout upon all who came to claim admittance. These sentries, too, were not only present, but appeared to be watchful and alert to all that went forward. Depressed at the evidence of the keen watch kept, but elated at finding a bank from which the rope and grapnel might be cast with some chance of success, Edgar and Peter returned to the poor dwelling at which they had obtained temporary shelter, there to await the time when their first attempt should be made. As on the evening before, the priest appeared and supped with them, more for company’s sake on this occasion, it seemed, than with any desire to keep watch upon them and their movements. Feeling a good deal of confidence in the kindly, careworn face with the steady grey eyes, Edgar told the priest what they had learned and how he proposed to effect an entrance. The news that the garrison was keeping a careful watch seemed to fill the priest with surprise and some concern. "Can it be that they have heard of your arrival?" he said. "And yet if that were so ’twould not be the posting of extra guards that I should expect, but the sally of a score of their blood-stained men-at-arms, who would pour into this village in an iron stream as they have done so often before. Ye would have been routed out, and within five minutes the branches of the nearest tree would have groaned beneath your weight. That is what has been before. Why, then, have they posted sentinels? Nothing else hath occurred save the arrival at the castle of a man who must indeed be of some consequence, seeing that he was accompanied by an escort of two men-at-arms." "When did this man arrive?" asked Edgar quickly. "On the morning of the day of your arrival--that is, yesterday." "Canst describe him to me?"
