If you actually did come into the city along Holborn, then when you ducked beneath that portcullis and entered the vaulted passageway beneath Newgate you'd see to the right a door leading into a porter's lodge, which was where new prisoners had their chains riveted on. A few yards farther along, you'd emerge from beneath the castle into the uncovered space of what was now called Newgate Street. To your right you would see a gloomy old building that rose to a height of three or four stories. It had only a few windows, and those were gridded over with bars. This was a separate piece of work from the turret-castle-vault building; rumor had it that it had once done service as an inn for travelers coming into the city along Holborn. But the prison had, in recent centuries, spread up Newgate Street like gangrene up a thigh, consuming several such houses. Most of the doorways that had once welcomed weary travelers were bricked up. Only one remained, at the seam between the castle and the adjoining inn-buildings. Going in there, a visitor could make a quick right turn into the Gigger, or, if he had a candle (for it grew dark immediately), he could risk a trip up or down a stairway into this or that ward, hold, or dungeon. It all depended on what sort of wretch he was coming to visit.
