He was thinking back to that straight and narrow passage. At its far end there was a sort of wicket, called by some the Gate of Janus, where prisoners entering the Bailey from the prison went to the left if they were females, and to the right if they were males, so that each sex was conducted into a different holding-pen. This was done strictly for appearances. Within Newgate, men and women mixed freely. But visitors to the Old Bailey saw strict segregation in the pens, and ( Jack supposed) heaved great sighs of relief to see that the place was run in a virtuous manner. As the sessions proceeded, the prisoners were let out of the pens one by one, and each returned a few minutes later. The lucky ones were literally smoking from freshly applied brands, the unlucky came back whole and unmarked, as they were destined for Tyburn, or for America. But at the end of the session, all of them—male and female, branded and condemned—were bottlenecked together through the Gate of Janus where they began their return up the chute to Newgate Prison. And just there, in the Old Bailey, near that gate, was a place where a free person might stand and gaze directly into the face of every prisoner who passed by.
