'He really is fascinated by things military,' said Eco as we walked towards the stream 'Where he picked up such an interest I can't imagine. I suppose he's always been fond of Marcus Mummius—

'More to the point, what have you been up to in Rome lately?'

Eco sighed. 'Somehow I didn't think you had come to fetch me just to have a look at your water mill.'

"There's not much point. The thing is a failure, like almost everything else on the farm'

'Things are going badly?'

We reached the mill. I found a shady spot and gestured for Eco to sit beside me. Together we stared at the hard, baked mud along the banks and the thin trickle of water over the stones. 'I shall tell you my troubles first,' I said. 'Then you'll tell me yours.'

I gave him a full account of all that had happened since we left Rome — the discovery of Forfex's corpse, the pollution of the well, the encounter with Gnaeus Claudius, the death of Clementus.

'Papa, you should have let me know. You should have written.'

'And you should have let me know about your dealings with Marcus Caelius.' Eco looked at me askance. 'I wrangled it out of Belbo,' I explained.'It wasn't hard.'

'And I confess, I already knew about the body in the well.'

'How—'

'Meto told me. Most of the story, anyway.'

'Yet you let me tell you the story again, as if you knew nothing!'

'I wanted to hear it from you, from beginning to end. Meto's account was more dramatic, but yours was more coherent. Meto seems quite proud that he was able to identify Forfex by the birthmark on his hand. You glossed over that in your version.'

'Did I? Meto remains convinced, I suppose, that Gnaeus Claudius is the culprit'

'He leans towards that opinion.'

'Even if Gnaeus Claudius were, I'd be powerless to press charges against him. But he knows now that we suspect him — I as much as told him I had proof against him, so if he is guilty, and if he's capable of being intimidated, notice has been served. But there's something else I wanted to talk to you about—'

'Papa, you act as if it were nothing, finding another headless body on the farm! And this time it was an act of malicious destruction, not just intimidation. Really, if the matter can't be resolved, I think you should bring the family back to Rome, before something truly terrible happens.'

'Eco, we've discussed this before,' I said impatiently. "There's no room for all of us at the house, and besides, I have no stomach for living in the city. Instead of my leaving the farm, I'd suggest that you leave Rome and come here. Better that than putting yourself in the hands of Marcus Caelius. What does it mean that you've allowed him to send you into secret meetings with Catilina and his circle? Don't you realize the danger?'

'Papa, I'm working for a Roman consul.'

'Slim protection if you're caught in some crime with these men and slain on the spot, or if they find out you're a spy and lay an ambush for you. Where will Cicero be then?'

Eco pinched the bridge of his nose. 'I know you've come to have a low opinion of Cicero in recent years, Papa. You seem to have lost respect for him entirely since he won his election against Catilina. But you must give him credit for being true to his friends.'

'Don't tell me you're spying on Catilina out of friendship.'

'Why, no, Papa, I'm doing it for money. You would be the one who's doing it out of friendship.' There was an edge in his voice I had never heard before — the voice that had always been beautiful to my ears because for so many years he was mute. We had never had a true fight before. I suddenly realized that we were on the verge of having our first. I looked away and took a deep breath. Eco did the same.

'I suppose it would reHeve my anxiety to a degree if you would explain to me the exact circumstances of your involvement,' I finally said. 'What is Catilina really up to?'

'What Marcus Caelius says is true: Catilina and his colleagues are compiling to bring down the state. They had hoped he would win the election, in which case he would commence his revolution from the top, using his consular powers and the powers of his friends in the Senate to bring about their radical reforms by law if they could, and by civil war if they couldn't. That was the route Catilina himself preferred. He seems to have thought he had a genuine chance of being elected. Now that the only course remaining to him is an armed revolt, Catilina hesitates. He finds himself ringed in by doubt and uncertainty.' 'I sympathize,' I said, under my breath.

'So far, the conspirators have done nothing illegal, or at least nothing that could incriminate them. They put nothing in writing. They meet in secret, sub rosa.' Eco smiled. 'Catilina is quite literal-minded about it; he actually hangs a rose from the ceiling in any room where his friends conspire, to remind them that the rose means silence and that their words must never reach the world beyond. Still, Cicero knows eveiything they do.'

'Because you spy for him.'

'I'm hardly alone. And I'm only a lowly spy, not a member of Catilina's inner circle. I belong to an outer tier of men he thinks he can trust and who, he thinks, may be valuable when the crisis comes. Still, I hear a great deal, and I'm good at sorting the truth from all the fantastic rumours woven through it. These people are full of grand delusions; sometimes I wonder if they pose any danger at all'

'Don't tell Cicero that! It's not what he wants to hear.'

Eco sighed. 'Papa, you're impossibly cynical.'

'No, that describes Cicero. Don't you see that he craves the role this crisis gives him? If there were no conspiracy against the state, I think he'd invent one.'

Eco gritted his teeth. We were again on the brink of a rupture. I drew back. 'Give me details,' I said. ‘Who are these conspirators? Do I know them? Who else spies for Cicero?'

'Do you really want me to tell you these things? Once spoken, they can't be unspoken. I thought you wanted to wash your hands of Rome.'

'Better to know than not know.'

'But secrets are dangerous. Whoever possesses them takes on the burden of keeping them. Do you really want that responsibility?'

'I want to know what company my son is keeping. I want to know who threatens my family, and why.'

'Then you've given up on hiding your head in the sand?'

I sighed. 'The feathers of the ostrich are highly prized, but easy to pluck. Burying his head in a hole gives him no room to manoeuvre.'

'And leaves his long neck exposed to daggers,' said Eco. 'A sharp observation.'

'A sharper pun.' We both winced, then laughed. I reached out and clutched his hand for a moment. 'Oh, Eco, you say these conspirators are deluded, but not half so deluded as I've been, imagining. I could escape from Rome. No one can! Ask any slave who's fled all the way to the Pillars of Hercules or the Parthian border, only to be trapped and carted back to his master in a cage. We're all slaves of Rome, no matter how we're born, no matter what the law says. Only one thing makes men free: the truth. I've tried to turn my back on the truth, thinking that by ignorance I could escape the Fates. I should have known better. A man can't turn his back on his own nature. I've lived my lite searching for justice, knowing how rare it is and how hard it is to find, — still, if we can't find justice, sometimes we can at least find the truth and be satisfied with that. Now I've given up on justice altogether, and I even seem to have lost my appetite, not to mention my instinct, for finding the truth, until I despair of ever finding it again; but to give up on that search is to be utterly lost.' I sighed and shut my eyes against the brightness of the shimmering leaves above. 'Do these rumblings make any sense to you, Eco? Or am I too old, and you too young?'

I opened my eyes to see him smiling sadly at me. 'I think you sometimes forget how much alike we are, Papa.'
