Book III

Quintus' mission in Britain continues - to find Barbillus' son, Rufus. But the news from the province is not good: Togidubnus, king of one of the British tribes, is seriously ill.

Prepare for a race against time as Quintus gets caught up in the murderous schemes and machinations of Gaius Salvius Liberalis, as we journey from the sacred spring at Aquae Sulis to the legionary fortress of Deva.
