At a certain point the arched passage was severed by a stone wall no more than about eight feet high, with a row of iron spikes protruding cheerfully from its top. Set into the middle of this was a grated doorway. Anyone could pass in, but only some could pass out. Daniel slowed as he approached this. Peter Hoxton had been acting as a sort of rear-guard, and almost piled into him. "You are permitted to go on," Saturn pointed out, looking this way and that at the Bench-people. For these had noted Daniel and begun to tender diverse proposals. Daniel ignored him, and them. He was staring at his feet. He flipped his walking-stick around and rapped its massive head against the paving-stones, moved to the side a couple of feet, and did it again. Finally he resolved to go in. But he got into a nasty collision, just before the door, with a young man. It was not nasty in the sense of being violent, nor in the sense of being acrimonious, for the young man tried to avoid it, and proffered a sort of apology after. He had been walking along behind Daniel and Saturn in traffic, and when they’d bated before the door, he had sought to go around them. The nastiness came from that he was a butcher’s boy, employed probably by one of the many shambles out in the rules along Fleet Lane, and so his clothes were soggy with blood and other body fluids of dead animals, and clotted with fæces and brains and feathers and hair. Some of it ended up on Daniel. The boy was aghast, particularly when he got it in his head that Saturn might retaliate; but Daniel smiled benignly and said, "After you, young man," and held out a hand. The boy pushed through the door, smearing it anew—for it looked as if many of his colleagues had preceded him—and civilly held it open for Daniel. Daniel and Saturn went in, passing by a whore (tertiary syphilis) and client (primary) waiting to go out, walked through the scrutiny of a turnkey, and emerged from the tunnel into one side of a stripe of open ground that lay athwart their path. The Prison building was directly ahead of them, an immense barrier stretching more than a hundred feet to the left as well as to the right, and looming high above. In half a dozen strides they could have ascended a few steps and gone right into it. But Daniel drew up short, and stopped again. His attention had been seized by a peculiar triptych of figures who were standing just within the gate, and who had no thought of getting out of Daniel’s, or anyone’s, way. One was a scruffy and beaten-down-looking chap, who kept turning to the left and right, as if mounted on a vertical spit. Next to him, looking on, was a fellow, slightly better dressed, leaning on a staff daubed all over with paint. A few paces distant stood a grim, heavy man who was staring at the first fellow in a way that normally would have provoked a row. The staring went on for an uncannily long time, and Daniel began to collect that it was some sort of rite. He noticed that the turnkey who was stationed by the gate was also staring, when he was not busy scrutinizing the faces of departing visitors; and this detail solved the puzzle for him, just as Saturn—who had been amusing himself watching Daniel try to make sense of it—gave the explanation: "New prisoner. These turnkeys have a faculty in common with thief-takers: they never forget a face, once they’ve given it a keen study."
