A group of rioters, including Hugh and Sim, arrive at the locksmith’s shop and call for Gabriel Varden. They demand that he join their march to Newgate. Gabriel comes out holding a gun and tells them that he has no intention of supporting their cause. Miggs calls out from an open window above, telling them that she is locked in the attic and giving them directions for rescuing her. She also tells them that she poured beer down the muzzle of Gabriel’s gun, rendering it useless. With a shout of laughter, the crowd overpowers Gabriel. They explain that since he made the locks of the prison doors, he must come with them to pick the locks. Gabriel refuses but the rioters gather up some tools and force him to go with them. Dennis wants to hang him, but Hugh protects him from the overzealous hangman. Miggs is rescued and brought downstairs, where she throws herself into Sim’s arms; he pushes her away. The rioters proceed to Newgate Prison to release the prisoners.

The mob arrives at Newgate and calls out to the jailer, demanding that he release the rioters who have been imprisoned. The jailer refuses, saying that he is bound to keep all the prisoners inside. Gabriel Varden calls out to him and identifies himself, telling the jailer that he has been brought by force to open the locks but he still refuses to do so. Gabriel shouts to the crowd to give him his daughter, who is still missing. Dennis hits Gabriel, knocking him down, but the locksmith bounds back up. The crowd rushes forward and one man attempts to kill Gabriel with a pole ax; a one-armed man strikes the attacker down and rescues Gabriel. A fire is started at the door of the prison, eventually burning it enough so that the rioters may enter, though the entire prison is now on fire. The jailer, his family, and his officers escape.

In his cell, Rudge hears the sounds of the mob and fears that they have come specifically to punish him for the murders. Soon the rioters enter the prison and release the prisoners from their cells. Rudge is reunited with Barnaby as they are removed from the prison. Dennis stands guard over four prisoners who are to be hanged in two days. Hugh orders him to release them, but Dennis, as a hangman, wants to see them punished for their crimes as scheduled. Hugh releases them himself. The rioters leave Newgate to burn.

Mr. Haredale arrives at the Newgate, too late to make sure that Rudge did not escape. He is still unable to find Emma despite searching nonstop since finding his home burnt down. Still in danger because of his religion, he is taken into the care of John Grueby (who had left his position with Lord Gordon) and his new employer, a distiller. They tell Mr. Haredale what has progressed in the riots, that the house of Lord Mansfield was burned while the Lord Mayor stood by and did nothing. Mr. Haredale is put to bed and gets some much-needed sleep.
