From this place, they passed through several strong gates, opened by other turnkeys from the inner side; and, having entered an open yard, ascended a flight of narrow steps, and came into a passage with a row of strong doors on the left hand. Motioning them to remain where they were, the turnkey knocked at one of these with his bunch of keys. The two attendants, after a little whispering, came out into the passage, stretching themselves as if glad of the temporary relief, and motioned the visitors to follow the jailer into the cell. They did so.
