Episode 3

Following the Great Fire, three different magnificent new designs have been presented to the King by Pepys' friends - John Evelyn, Christopher Wren and Robert Hooke. But plans for an ambitious new London are soon watered down. The city is losing money fast because of the disruption to trade. They must get the city back to work as soon as possible. Utopian visions are out, and compromise is the order of the day. Meanwhile, demolition work at St Paul's Cathedral causes problems with the neighbours, and another fire, this time at Sam's home in Seething Lane, threatens not only the occupants but his precious library.
