I thought this was one-sided. For one thing, my research in Rome among despatches about the rebellion had told me that Augusta Treverorum, the nearest tribal capital, had produced Julius Tutor and Julius Classicus, two of the most hotheaded rebel leaders after Civilis, so feelings ran higher here than our friend wanted to admit. But I didn't blame Mordanticus for taking the convenient view.

I changed the subject. 'What I saw happening at Lugdunum smacked of commerce rather than politics. I gather there is a strong professional rivalry between you and the Gauls. Is it all to do with your military trade?'

He nodded, albeit reluctantly. 'A big question mark hangs over who will win the contract for the new legions at the fort. Lugdunum itself is under threat from a big consortium in southern Gaul. Bruccius and I had been trying to persuade the new legate to re-award the franchise locally.'

'That legate was Florius Gracilis?'

'The same. The other man takes a much less prominent role.'

'Yes, his troops were recruited from the navy, and are rather diffident. So, your people held the franchise previously, when the Fourth and the Twenty-second were the legions based at the fort?'

'With reason! Our produce matches the quality of Italy or Gaul, and obviously distribution is easier.'

If there was suitable clay here, Rome would naturally have encouraged a local industry, setting it up with official finance, no doubt, during the old campaigns under Drusus and Germanicus. Having established local production and persuaded people to make working for the legions their livelihood, it would then be hard to turn elsewhere. But Rome had never had much love of sentiment.

'How do your prices compete?' I asked.

He looked reproving. 'For a tender with the legions, our prices are set right! Anyway, we have no transportation costs. I refuse to believe Lugdunum can undercut our bid.'

'Unless they cheat! Was Gracilis sympathetic?'

'He never answered us directly. I felt our pleas were making no impression on the man.'

I frowned. 'Had he been got at?' Mordanticus shrugged. He was the kind of ultra-cautious businessman who never commits himself to speaking ill of those he may be forced to deal with at a later date. It looked to me as if he would have to take a more robust line. 'Let's face it, Mordanticus,' I insisted. 'Florius Gracilis would have come out through Gaul this spring by the same route that I took. He has a young wife who probably wanted new dinner-party dishes and would have dragged him to the factory site at Lugdunum. He could easily have been nobbled by your rivals before he even arrived here. You know it, don't you? The big boys at Lugdunum had stitched the legate up.'

Without directly answering, Mordanticus said, 'The potters here decided to make a last effort to sort things out, and Bruccius was elected spokesman for all of us. We sent him over to Lugdunum to try and reach a compromise. There's business for everyone. Those bullies in Lugdunum are just greedy. They already have a roaring trade in Gaul, all the legionary orders for Britain, plus Spain. They export from their southern ports all round the Ligurian Gulf and the Balearic Coast.' He spoke like a man who had eyed up the commercial possibilities carefully himself. 'They were always bitter that we were right here on the spot. After the rebellion, they saw their chance to muscle in.'

'So, it seems likely that Bruccius and his nephew did what they could there, but received no help. Things looked to me on the verge of violence, but your friends showed no physical damage when I saw them having supper the night they were killed. They must have given up on the Lugdunum mob, and were coming home with the bad news. Mind you,' I said thoughtfully, 'it means the question of who gets the franchise cannot be settled yet.'

'Why do you say that?' enquired Helena.

'No point murdering two people if Lugdunum felt confident the future trade was theirs. It's my belief the potters from Gaul felt Bruccius could be far too persuasive. With the Rhine legions right on his doorstep and the relevant legate within daily reach, he and his colleagues could pose a serious threat. That was why Lugdunum wiped him out. Somebody tracked him and the nephew far enough to deter any magistrates from making a connection, and then killed them in a spot where they might never be identified at all.'

'But why?' asked the potter. 'It still leaves plenty of us here.'

'Mordanticus, for the oldest motive in the world! Killing two of your number-or better still, having them totally disappear-will intimidate the rest.'

'No chance!' Mordanticus declared with a set face. 'We shall never give up, or let them get away with it!'

'You're a strong-willed man, but I warn you, some people will soon quaver at bullying. Don't forget there are potters with wives who don't want to be widows. Potters worried about the fate of large families if their breadwinner vanishes. Potters who just feel life has more to offer than a long-drawn-out feud which they may never win.'

'It's criminal!' raged Helena. 'Rome shouldn't even appear to sanction business methods of this type. The legate ought to show his disapproval by barring Lugdunum completely, then awarding to Moguntiacum every franchise that's available!'

I smiled at her for becoming so passionate. 'From what I've heard about Florius Gracilis, we can't rely on him for a high moral tone. I know he's desperately short of cash.'

'You mean he's taking bribes?' Helena's parents' attempts to give her a sheltered life had been partially successful. But since meeting me she had learned enough not to be surprised at any suggestion. 'Is Gracilis corrupt, Falco?'

'That would be a grave charge. I'm not making it.' Not at this stage, anyway. I turned to the potter. 'Julius Mordanticus, I work for the Emperor. Your problems ought not to be my business, but they may overlap with what I came to do.'

'Which is what?' he asked curiously.

I saw no reason to hide the truth. 'Principally, to liaise with Civilis. His current whereabouts are unknown, but I believe the legate may be searching for him. On the other hand, Gracilis could have gone after Veleda, the Bructian prophetess.'

'If he has crossed the river, he's a fool!' Mordanticus looked at me as if I was mad merely for suggesting it.

'Don't say that. I may soon have to cross the river myself.'

'You're in for a wild time, then. And I should say it's death for Gracilis.'

'He may be travelling incognito.'

'A Roman official is pleading to be spotted. Is this something to do with the franchises?' Mordanticus demanded, single-mindedly.

'No, it's all about political glory for Florius Gracilis. But it means you and I have a shared interest. I don't like to make promises, but if I ever run across him I may well find an opportunity to discuss your franchise problem, and I may just make him believe that I am speaking for Vespasian.' For some reason, the Emperor's name carried weight. In a town that could compliment Nero on a civic column I should have expected it. Mordanticus looked as grateful as if I was signing his precious pots contract myself. 'Can you help me to arrange a meeting, Mordanticus? Do you know anything about the legate's recent movements, or even where I might find Julius Civilis himself?'

The potter shook his head, but promised to make enquiries. He still looked dazed. We left him to break the news of what had happened to his two colleagues. I did not envy him. He had told me there were young families involved.
