'At any rate, this man from Hortensius comes to my door. Asks me all sorts of unrelated questions, tells me nothing-lots of mystery, lots of posing, the sort of wheedling these types engage in when they want to know if the opposition has already approached you about a case. They always think the enemy has got to you first, that you'll go along and pretend to help them anyway, then stab them in the back at the last moment. I suppose it's what they themselves would do in my place.

'Finally he goes his way, leaving a smell in the foyer that Bethesda can't eradicate with three days' scrubbing, along with only two clues as to what he was talking about: the name Roscius, and the town of Ameria - did I know the one, had I ever been to the other? Roscius is the name of a famous comedian, of course, one of Sulla's favourites, everybody knows that. But that's not whom he meant. Ameria is a little town up in the Umbrian hill country, fifty miles or so north of Rome. Not much reason to go there, unless you want to take up farming. So my answer was no, and no again.

'A day or two passed. Hortensius's handyman didn't come back. I was intrigued. A few questions here and there — it didn't take much checking to uncover what it was all about: the parricide case upcoming at the Rostra. Sextus Roscius of the town of Ameria stands accused of plotting the murder of his own father here in Rome. Odd — no one seems to know much about the matter, but everyone tells me I'm better off staying clear of it. An ugly crime, they say, certain to be an ugly trial. I kept expecting Hortensius to contact me again, but his creature never reappeared. Two days ago I heard that Hortensius had withdrawn from the defence.'

I gave Tiro a sidelong glance. He kept his eyes on the ground as we walked, hardly looking at me, yet I could almost feel the intensity of his concentration. He was an excellent listener. Had he been other than a slave, what a fine pupil he would have made, I thought; and perhaps, in another life, in another world, I might have made a fine teacher of young men.
