In A Tale Of Two Cites summarize and describe the court room in Book 2, Chapter 2.
Within the setting of "The Tale of Two Cities" conditions were anything but sanitary. Consequently, diseases spread easily, especially among the poor, who would populate the prisons and courts. For this reason Dickens states that
the judge in the black cap pronounced his own doom as certainly as the prisoner's, and even died before him. For the rest, the Old Bailey was famous as a kind of deadly inn-yard...
Many in the Old Bailey contracted tuberculosis, scarlet fever, and other highly infectious, deadly diseases such as "gaol fever." Nevertheless, people crowded into the court for a show, just as they went to the mental asylum, Bedlam.
As Jerry Cruncher enters to deliver a message to Mr. Lorry, who sits beside a gentleman looking at the ceiling (Sydney Carton), the spectators strain in an "ogreish" manner to see the prisoner, who has been accused of treason. They strain and stare because he may soon be drawn and quartered and hanged. Dickens describes the scene
The accused, who was (and who knew he was) being mentally hanged, beheaded, and quartered, by everybody there, neither flinched from the situation, nor assumed any theatrical air in it.
An overhead mirror which allows the audience to see the face of the accused. When the accused feels light across his face, he looks up and flushes as he realizes his face is being reflected. As he turns he looks upon two persons seated in the corner of the judge's bench. This sight disturbs, so much so that the spectators, too, turn to them. They are a beautiful young woman and her father--Lucie and Dr. Manette, witnesses against the accused, the spectators learn.
