'I see.' Talmis nodded and looked at him with a calculating expression. 'Legate, do you think your victory has ended my ambitions to seize the upper Nile?'

'No. But it will take time for you to mass another army. By then Rome will have sent more troops to the province and bolstered the defences of the towns and forts along the Nile. You will have even less chance of success than you did this time.' Cato looked at him steadily. 'I don't think Rome will have much to worry about from the Nubian quarter for a while. You're a spent force. Ajax, on the other hand, is not. That is the reason why I am prepared to trade your life for his.'

A frown flitted across the Prince's face. 'Really? I think you underestimate me, Roman. We shall see about that, perhaps sooner than you think.' Prince Talmis turned to the captain of his bodyguards and there was a quick exchange before the captain dismounted and climbed down the bank to the edge of the water. He raised a small horn to his lips and blew four times. Two figures scurried down from the shrine, boarded the skiff and set off across the current.

Cato gestured to the commander of the cavalry escort to join him and then spoke quietly to the decurion. 'I don't trust the Prince. I want your two best men to come with me. Once we reach the island and have the prisoners, I'll give the signal for you to release the Prince and his men.'

'Yes, sir. And what'll the signal be?'

Cato thought briefly. 'I'll raise my sword and wave it from side to side. You'll see that well enough from here.'

'Yes, sir.'

Cato glanced at the Prince and his men. 'If they make any attempt to escape before the signal is given, kill the men. Take the Prince alive, if you can.'

Macro moved closer to Cato and muttered, 'What's to stop us killing him anyway? Once we have Ajax?'

Cato shook his head. 'Talmis poses little danger to Rome. I think that this defeat will weaken him. He'll be busy keeping his followers in line as it is. If we kill him, we give the Nubians a grievance that will need to be avenged.'

Macro shrugged. 'If you say so. Frankly, one more dead Nubian suits me fine.'

Cato nodded to the decurion. 'You have your orders.'

The decurion turned in his saddle to call back down the line. 'Castor! Decius! Dismount and escort the legate!'

The two tough-looking men swung down from their saddles and handed the reins to their comrades before unhooking their shields and trotting forward to the two officers. Cato dismounted and gestured to them to follow him. 'You too, Macro. And you, Junius.'

He led the way down to join the Nubian captain as they waited for the skiff. The men in the small boat worked the oars hard as they fought the current. As they waited, Cato stepped aside from the others. 'Macro, over here.'

They moved out of earshot and Cato turned to his friend with a searching look. 'When we get hold of Ajax it is my intention to take him back to Rome alive. Do you understand?'

Macro was silent for a moment and his expression hardened as he replied through gritted teeth. 'After all that bastard's done? You haven't forgotten Crete, Cato. But then it wasn't you he held captive in that shitty cage. It was me, and Julia.'

'I know.'

'Bollocks. I say we kill him, dump his body in the Nile and be done with it.'

'Those were not our orders.'

'Orders?' Macro leaned closer, face to face with Cato. 'Fuck the orders… Fuck 'em. Fuck Sempronius, Narcissus, the Emperor. Fuck the lot of 'em. I don't care. Ajax owes me, and I want my revenge.' He paused and softened his tone as best he could. 'Cato, lad, I need revenge, and so do you, for Julia's sake.'

'I won't speak for her.'

Macro stabbed his finger at Cato's harness. 'She's going to be your wife. Do you think you can live with that precious conscience of yours, knowing what he did to her and yet letting him live an instant longer than necessary?'

'Ajax will die,' Cato replied firmly. 'He will be condemned by the Emperor and crucified. You know it.'

'Oh, he'll be condemned all right, but what if Claudius decides to send him to the arena? You know how good he is. If anyone can win over the mob, it'll be Ajax. Then what? Supposing Claudius spares him, as a sop to the mob? Even if he dies, he'll go out a hero. Either with a sword in his hand spitting defiance, or screaming his hatred of Rome from the cross. If he's crucified, he'll be a martyr, just like Spartacus before him.'

'Then we'll have to bridge that cross when, or if, we come to it.' Cato grasped his friend's arm. 'Macro. We have no choice. We have our orders and I will carry them out. And so will you. Give me your word on it, or I'll have no choice but to send you back to the camp.'

Macro's face flinched with the effort of containing the poisonous rage that Ajax had planted in his heart many months before. At length he sucked in a deep breath through his teeth. 'As you command… sir.'

'Thank you.' Cato bowed his head slightly in gratitude before he glanced towards the river. 'The boat's here. Let's go.'

They returned to the others as the skiff reached the shore. One of the men hopped over the side with a splash and guided the bows in. The captain climbed aboard and settled in the stern before the others took their places; Macro and Cato opposite the captain, then the two auxiliaries and Junius on the small triangular deck at the front. The Nubian pushed the boat off and the man at the oars turned the craft and started to propel it back across the glassy expanse of river towards the landing stage on the island. One of the legionaries leaned out to look down at the water and the boat rolled slightly to that side.

'Sit back!' Macro snapped. 'Don't move again.'

'Sorry, sir.'

The skiff was heavily laden and awkward to move and the man at the oars had to work hard to keep on course. The sun was beginning to sink into a murky orange haze to the west and the dark forms of birds swooped low over the water, feeding off the insects. They were not the only animals feeding, Cato realised as the skiff approached the landing stage. There was a movement in the reeds away to the left and a long glistening snout protruded briefly through the slender green growths, then with a swirl of water and swish amongst the tops of the reeds, it was gone.

The skiff approached the landing stage, constructed from stone in the forgotten days when priests once came to the shrine to make offerings. Now the stone was worn with age and mottled with bird droppings. The man at the oars shouted over his shoulder to Junius, and then pointed to the rope loosely coiled beside the tribune. Junius nodded his understanding and took up the rope, reaching out to the iron ring that was fastened to the side of the stonework. A thrust of the oars brought it within reach and the tribune grasped it and pulled the boat in. As soon as he could he slipped the end of the rope through the ring and pulled it back, drawing the craft closer. Once the craft was securely moored, Junius clambered ashore and helped the others up. When they were all on firm ground, Macro turned to the Nubian captain.

'You speak Greek?'

'Little.'

'Then no tricks, understand?' Macro slapped his scabbard. 'Or else.'

The captain nodded and then led the way up a crumbling stone path lined with palm trees. It was only a short climb before they emerged close to the entrance to the shrine. Cato turned back and saw the distant figures watching them from the riverbank. Then he strode towards the entrance with the rest of the party, his heart beating swiftly as he anticipated the meeting with Ajax. At his side Macro's expression was grim and his lips pressed tightly together. The two auxiliaries followed Macro, and Cato and Junius took up the rear. The sentry at the gate saluted as he saw the captain and there was a brief exchange before the Nubian led the party inside the shrine.
