Summary Queen Catherine confronts her wayward husband with the news that if the fire reaches the Tower of London it will ignite powder kegs stored there and blow up the whole city. As a result he joins James and the fire-fighters and makes sure that houses are demolished to stop the spread of the blaze, assuring compensation. Hysteria breaks out as Catholics and foreigners are accused of arson and lynched, despite Samuel Pepys's efforts to intervene. Denton rearrests Sarah, planning to use her as a scapegoat to appease the mob and the Farriners approach Pepys, whose wife persuades him to take Thomas to see the king and explain how the fire really started. Told that the fire has been halted the king urges the citizens to look forward to rebuilding London, rather than putting the blame on outsiders and Sarah is released.
