Nero has been emperor for ten years and many fear him. Nero particularly dislikes Christians, who worship their own God instead of the emperor, and has had some arrested and killed. A great fire breaks out in the city, and Bryn and his friends escape to the outskirts, to the home of a rich slave-trader, Septimus.
Bryn returns to the city to see the damage and finds a city in ruins. However, he also seems members of Nero's own Praetorian Guard setting fire to houses.
Rumours fly that the Emperor has had the fire started deliberately in order to clear ground to build a grand new palace, but others blame the Christians.
Bryn is amongst those arrested. Nero wants to round up a hundred Christians and have them set alight as a mighty spectacle.
Will Bryn and his friends survive?
