Caerleon, once a Roman town, was more than two thousand years old. The muddy, glistening banks of the River Usk bisected the old from the new town, and from the copter she could see the incredible amphitheater and Roman bullring, with its concentric stone circles ringing the field of battle. Clustered around it were a complex of shiny, flat-roofed buildings, the Transys corporate complex, wrapped up delicately within a web of triple security fences and a whole army of private security.
