By now it was clear that our planned intimate evening had been hijacked. `Rutilius and I had lost all control of events. The atmosphere of expectation grew. Physically, we had a very lopsided audience, for the prince and his party of flunkies loomed large on the left-hand side, encroaching on the free space we had wanted to preserve, and blocking the view for our private friends and family behind. Even Rutilius looked slightly annoyed. Total strangers were milling about in the body of the hall. Helena kissed me formally on the cheek; she and Petronius abandoned me to find seats somewhere.

We tried clearing our throats diffidently; nobody heard.

Then order somehow imposed itself. Rutilius was taking a last rattle through his scrolls, ready to start first. He had an armful, whereas I had only one, with my dubious opus copied out for me by my womenfolk; Helena and Maia believed bad handwriting would cause awkward pauses if they left me to my own devices with the original note-tablets. It was true that my efforts seemed to acquire a new dignity once they were written out in neat three-inch columns on regular papyrus. (Helena had invested in the papyrus as a gesture of support; Maia had wanted to economise by using the backs of old horse-medicine recipes, the only legacy her husband had left her.) I was twisting the copy, unwittingly tightening the roll on its roller to danger point, while pretending to grin encouragement at Rutilius. Then to our astonishment, the bearded man who was at the centre of the gatecrashers moved to the area in front of the terrace where we were intending to perform.

Now I got a better squint at him: grey hair bushing back from a square forehead, with coarse grey eyebrows too, although those looked as if they had been powdered with beanflour to make them match his silvered hair. He had a limp demeanour with knowing overtones – in personality a nobody, but a nobody who was used to getting in other people's way.
