I judged him on the facts alone. Fortunately for Titus Flavius Domitianus, second son of Vespasian, as a mere informer I did not count. But we both knew what I thought. During his machinations, he was responsible for the murder of a young girl towards whom I had once felt some tenderness. `Responsible' is a diplomatic euphemism there.

Domitian knew that I held damning information, reinforced by well-stashed evidence. He had done his best to keep me down – so far only daring to delay my social promotion, though the threat of worse would always exist. So too, would a threat against him from me, of course. We both knew there was unfinished business between us.

This now promised to be a difficult evening. The uppity young Caesar had been demoted to running literary prizes. He seemed to judge them impartially – but it was unlikely that Domitian would be a friendly critic of my work.

Brushing off everyone else except Rutilius, the princeling swaggered by, in company with his glamorously tricked out wife, Domitia Lepida – the great general Corbulo's daughter, a spectacular prize whom Domitian had blatantly carried off from her former husband. He ignored me. I was getting used to that tonight.

In the excitement, the gatecrashers managed to gain entry, but it now seemed best to allow in the largest audience we could commandeer. Among the final comers I suddenly saw Maia; she made a typically swift arrival, her dark curls and self-possessed air turning heads. Petronius Longus made a move to escort her to a seat, but she squeezed through the press, bypassed both Petro and me, boldly made her way to the best position in the room, and forced herself a niche alongside Ma. The imperial party should have been ensconced in state there at the apsidal end, but they remained to one side. Courtiers hoicked themselves up onto shoulder-high wall ledges. Domitian deigned to sit on a portable bench. I recognised – as Rutilius may not have done – that this was a courtesy visit only; the royal troupe had dropped in to be gracious, but were leaving themselves space to make a getaway as soon as they grew bored.
