A party of slaves, under the escort of overseers and in charge of a knight who had been with them at their work on the fortifications, were passing along the street on their way back to barracks.  It was already dusk, and as Gervaise was going the same way as they were, he stood aside in a doorway to let them pass.  He was on the point of stepping out to follow them, when he saw a man, who had been standing in the shadow of the wall, fall in with their ranks, and, as he walked engaged in an earnest conversation with one of the slaves.  He kept beside him for a hundred yards or so, then passed something into the slave’s hand, and turned abruptly down a side opening.  There were but few people about, and in the growing darkness the action of the man passed unobserved by the overseers.  Gervaise, thinking the occurrence a strange one, turned down the same lane as the man.

He slackened his pace until the latter was fifty yards ahead, so that he would not, had he looked round, have been able to perceive that it was a knight who was behind him.  After passing through several streets, the man turned into a refreshment house.  The door stood open, and as the place was brightly lit up, Gervaise, pausing outside, was able to see what was going on inside.  The man he had followed was on the point of seating himself at one of the tables, and as he did so Gervaise recognised him as the Greek he had met at the merchant’s house.  He at once walked on a short distance, and then paused to think.

The vague suspicions he had before entertained as to the man now recurred with double force; he was certainly in communication with one or more of the slaves, and such communication, so secretly effected, could be for no good purpose.  So far, however, there was nothing he could tax the man with.  He would probably deny altogether that he had spoken to any of the slaves, and Gervaise could not point out the one he had conversed with.  At any rate, nothing could be done now, and he required time to think what steps he could take to follow up the matter.  He resolved, however, to wait and follow the Greek when he came out.  After a few minutes he again repassed the door, and saw that the man was engaged in earnest conversation with another.  After considering for a time, Gervaise thought that it would be best for him to follow this other man when he left, and ascertain who he was, rather than to keep a watch on the movements of the Greek, who, as likely as not, would now return to the merchant’s.

He walked several times up and down the street, until at last he saw the two men issue out together.  They stopped for a moment outside, and then, after exchanging a few words, separated, the Greek going in the direction of the quarter in which lay the house of Vrados, while the other walked towards Gervaise.  The latter passed him carelessly, but when the man had gone nearly to the end of the street, he turned and followed him.  He could see at once that he was a lay brother of the Order.  This class consisted of men of an inferior social position to the knights; they filled many of the minor offices, but were not eligible for promotion.  Following for ten minutes, Gervaise saw him approach one of the barracks, or prisons, occupied by the slaves.  He knocked at the door, and, upon its being opened, at once entered.
