'Of course!' Petronius responded loudly. 'And I am sure that you are equally concerned to protect the lives of the crewmen of the ships carrying your goods.'

The merchant shifted uncomfortably as he nodded. 'Naturally. It goes without saying that the well-being of our employees and shipping contractors is also close to our hearts.'

'Assuming they actually have hearts,' Macro muttered under his breath.

'That's quite an assumption,' Cato replied softly.

Petronius glanced at them and then turned his attention back to the Alexandrians' spokesman as the latter continued. 'Sir, the question I asked is unanswered. What are you going to do about this renegade?'

'The matter is in hand. Prefect Cato is leading a special task force with orders to find and destroy the renegade slave.'

'Clearly the prefect hasn't had much luck so far!' a voice called from the crowd. There was an angry chorus of agreement before Petronius held up his hands and demanded that they hear him out.

'I have utmost confidence in Prefect Cato. He is the best man for the job and it will only be a matter of days before he completes his mission.'

'How many days?' another merchant asked. 'It's already been more than a month since the trouble started. Another month will kill my business.'

There were more shouts, against a backdrop of bitter disgruntlement.

'Quiet there!' the prefect called out anxiously. 'Quiet, I said! Prefect Cato will have every military resource in Alexandria made available to him in order to facilitate the capture or destruction of Ajax.'

Macro nudged his friend. 'That's news to me.'

'And me.' Cato smiled faintly. 'Most welcome news.'

'What else could I say?' Petronius said irritably as he conferred with the two officers in his private quarters after the audience. 'You heard 'em. Their mood was almost rebellious. A number of them have influential contacts in Rome. If that isn't bad enough, the last two emperors have handed out Egyptian estates to their favourites as if they were party snacks. Even Narcissus has a few parcels of land in the delta. The trade in grain and other produce from those estates is being put in jeopardy by Ajax. Narcissus is the kind of man of influence that I'd rather not get on the wrong side of. So it's vital that Narcissus and his friends know that I am doing all that I can to keep a lid on the tensions here in Alexandria.'

'But you're not going to actually give us what we need to do the job, are you, sir?' said Macro.

'No. I can't. I told you, our forces are stretched thinly as it is. I can't afford to send them on some damned wild goose chase.'

'It wouldn't be a wild goose chase if we had more men and more ships,' Macro persisted. 'We could cover the ground more quickly, and be there in overwhelming strength when we eventually find Ajax.'

'If you find him.'

'We'll find him,' Cato said firmly. 'You have my word on it.'

'What if he quits the delta?' Petronius asked. 'What if he sails north, or west? What then? You'll be wasting time chasing shadows.'

'He won't leave the area. Why should he? He's doing a great job of stirring up local feeling against Rome. He'll stay here as long as he thinks he is undermining our interests in Egypt. Give us the fleet and we can find him and trap him in short order.'

'Give you the fleet?' Petronius smiled mockingly. 'I'm already having to use the marines to supplement the city watch. Besides, every available man is needed to counter the Nubians.'

'I need the fleet,' Cato insisted.

Petronius breathed in sharply and briefly considered the demand. 'I'll give you six more ships. But only for one month. That's as long as I can spare them.'

Cato considered the offer. Eight ships in all should be enough to deal with Ajax and his men, but the limited time was a problem. 'One month might not be enough.'

'That's all you have. After that I want you and your men to join the command of the legate of the Twenty-Second at Diospolis Magna. I suggest you get moving, Prefect.'

'It's like hunting for a grain of sand in a sack of salt,' Macro complained as he followed Cato and Hamedes along the strip of shingle towards a handful of beached fishing boats. 'Bloody Ajax is all but invisible.'

'We will find him,' Cato replied evenly. 'Whatever it takes.'

'It's not whatever that matters, but whenever. The month is almost up, Cato. If we don't find him in the next five days we will have to give up the search.'

'I am well aware of that, Centurion.'

Macro pressed his lips together in a thin line. The failure to find Ajax had tested his friend sorely, and Cato had recently developed a strategy of referring to Macro's rank when he grew weary of discussion or did not want to be contradicted. So they continued in silence walking steadily down the beach towards the fishermen, who were absorbed in the task of plucking the writhing silver fish from their nets and tossing them into baskets. Hamedes went first, ready to speak to the natives in their own tongue and reassure them that the three of them posed no threat. The priest had willingly volunteered to join the hunt when Cato had asked him to act as their guide and translator. The temple at Keirkut had been his life. Recruited to the priesthood when barely a child, it was the only family he had ever known and the desire for revenge burned in his veins.

Cato and Macro wore only their tunics and belts, with the dagger scabbards tucked out of sight behind their backs. Hamedes wore the simple flowing robe of the fellahin. The fishing boats had been sighted by one of the skiffs that Cato had sent in to patrol the Mendesian mouth of the Nile. The rest of the flotilla lay in a shallow cove by the sea. Cato and the others had landed out of sight of the fishermen and removed their armour before approaching them.

Due to the predations of Ajax, it had been difficult to gather any intelligence from the smaller Egyptian settlements along the coast. At the first sight of a Roman sail, or men in Roman uniform, the villagers had simply fled. The only news that Cato had gleaned from the locals had come from chance interceptions of the few vessels that had dared to put to sea, and the handful of times when they had been able to approach people without causing them to run and hide, as now.

'They've seen us,' Macro muttered as one of the fishermen looked up when they had closed to within a hundred paces. At once the man called out to his friends and they dropped their nets and snatched up their clubs and gutting knives. They were torn between abandoning their catch and running, or staying to confront the three men approaching them. There were twelve of them, Macro counted, odds of four to one, if there was any trouble. The fishermen were thin and sinewy and were not professional fighters. Even so, the overwhelming advantage in numbers lent them sufficient courage to stand their ground as they warily watched the three men making their way towards them.

'Tell them we mean no harm,' Cato said to Hamedes. 'We want to buy their catch, and talk.'

Hamedes nodded and called out a light-hearted greeting. The nearest of the fishermen replied sharply, holding out his hand, clearly commanding them to stop. There followed a brief exchange before Hamedes spoke softly to Cato. 'I've told them who we are. The one speaking for them is the headman of their village. He asks if we are alone. I said we are.'

Cato nodded uneasily and hoped that the marines he had left back at the skiff did as they were told and kept out of sight. 'Ask him if he has seen any other Romans recently.'

There was a lengthy exchange in which the headman jabbed his hand downriver. A moment later the priest turned back to Cato. 'A warship entered the mouth of the river several days ago. It stayed for the night and left the next morning.'
