Emperor

only had to follow the smell of musty old books.'

'Audax.'

Tears embarrassingly pricked Thalius's eyes. 'I'm such a fool. I was somehow expecting the boy. Why, how you have changed! I really wouldn't recognise this great tree of a man as having grown from the wretched sapling I found in that gold mine, all those years ago.'

But Audax's face clouded a little, and Thalius understood there were layers of memory probably best left undisturbed.

He went on hurriedly, 'Besides, you know, with my head full of books I had quite forgotten that I was here to look for you. I'm like that nowadays, I'm afraid. And now here you are caring for me, as poor Tarcho looked out for me all those years.'

'It's been a long time.'

'And how is your wife?'

'Melissa is well. We have a townhouse in Constantinople-smaller than yours, Thalius, but it suits us well.' He said cautiously, 'Things seem to be better out there. In the east. There are lots of small farmers who own their own land. It's not like here where you have whole swathes of the country owned by a few super-rich. You don't have the same-' He waved a hand, his soldier's inarticulacy betraying him.

'Gross inequality?' Thalius finished for him sadly. 'I know, Audax, it is ruining us all, that and the decline of education…But you have sons. Tarcho told me all about them. Your letters always thrilled Tarcho.'

Audax smiled. 'I called the older boy Tarcho-another soldier I think! But the younger has brains rather than brawn. He's more like you, Thalius. We are family after all. I'm glad I named him after you.'

Thalius was thrilled. 'It would be wonderful if you lived closer, so I could get to know him-tutor him a little, perhaps.'

'My place has always been at the Emperor's side.'

'I understand.'

'Anyhow I'm here now-here for the first Tarcho…'

'Yes. Poor Tarcho! Come. Walk with me.'

They moved away from the book stall and, with Audax's broad shoulders and military insignia easily clearing a way, they walked up the stairs, through the colonnade and into the Temple. It was a relief for Thalius to reach the comparative calm beneath the Temple's roof, but it was painful to walk.

Audax touched Thalius's arm, offering support. 'How do you feel?'

Thalius gasped, 'As if that thug buried his arm in me up to the elbow.'

'If you feel you need a doctor-'

'I'd rather walk with you, old friend.'

Audax glanced around at the Temple. 'I haven't been here since I was a child, and then I was too young, or bewildered, to make sense of it. Surprisingly grand, isn't it?'

'You mean for a run-down province like this one? Well, so it is, but it's lasting the years well.' Though there was some rubbish strewn on the floor, and the dead leaves of the summer just ended, the grand old monument wasn't in terribly bad shape. You could see where money was being spent on it by those townsfolk like Thalius himself still civic-minded enough to care: repairs to the roof tiles, refurbishment of frost-cracked pillars. 'But it has been rededicated to Christ, as well as to the divine Claudius.' Thalius pointed out a labarum propped up in one corner, the emblem of a soldier-Christian.

'It is still standing,' Audax said, 'which is more than can be said for many pagan temples these days.'

Since that fateful and last visit to Britain all those years ago, Constantine had pressed ahead steadily with his programme of converting his empire to Christ. He had played a long and patient game, but as the power of pagans in the ruling classes and the army had steadily diminished, he had at last felt able to proclaim Christianity as the empire's prime religion-and to command a reformation. The wealth of the pagan temples was turned over to the Church, and the imperial treasury.

Audax rubbed a clean-shaven chin. 'I was involved in some of that. As money-making schemes go that was a good one, even for an emperor who always had a nose for cash like a dog for a bone.'

Thalius laughed, but winced at the pain. 'That's cynical for a soldier of the Emperor's bodyguard!'

Audax shrugged. 'You can be realistic and loyal at the same time, can't you?'

'True. As was Tarcho, always.'

'I'm not surprised the Temple of Claudius has survived. Even Constantine could hardly order the stripping of shrines to his own deified predecessors-especially as he is to be made a god himself.'

Thalius gaped. 'You're joking! After a lifetime of promulgating Christianity? Well, it will be a popular move here. They always loved Constantine in Camulodunum. Soldiers' town, you know. And that mother of his-they are thinking of adopting her as a patron saint!'

'Well, I know one thing for sure. Tarcho was a good Christian, of his kind. And he would never wish to be buried here.'

'No indeed,' Thalius said. 'Come, let's visit him.'

They crossed the temple floor, threaded their way down the steps through the crowded market stalls, and made their way along the city's principal street. Once an axis of the invaders' fort of Claudian times, it was rubbish-strewn, its gutters clogged with dirt.

And as they walked, they spoke of the aftermath of the night of Aurelia's attempted assassination of the Emperor, the night that had entwined their fates for ever.

Constantine himself survived. His Greek doctor said that though his wound was deep, the narrow blade had fortuitously missed any major organs. Aurelia herself, who had hidden her fanaticism from Thalius until the moment of the attack, was cut down immediately by the blades of the Emperor's guards, and that was the end of her. Tarcho shielded Thalius and Audax from the guards, but they had all been taken into custody as the search for complicity began. The worthy missive Thalius had haplessly carried might have been enough, in the fevered atmosphere of a paranoid court, to see him executed. Thalius always believed it was Tarcho himself who saved him, by arguing forcefully with his military accusers for Thalius's naivete and innocence-not to put too fine a point on it, his stupidity.

As for Audax, he could have been executed with no questions being asked at all-or at the minimum tortured, for under Roman law slave testimony was only valid if extracted under torture. But if Tarcho had saved Thalius it was Constantine himself who saved Audax. In those moments when they had been joined in an embrace of life and death, the Emperor had seen something he liked in the slave, and he had pledged to protect him. When the fuss had died down Thalius hastily granted the boy his freedom and gave him into the care of Tarcho, who he judged was likely to do a much better job of keeping the boy safe than Thalius himself ever could.

As for the other principal in the drama, Ulpius Cornelius had made noises about the betrayal of his trust, receded into the shadows of the court, and Thalius had never seen him again. And he never knew if Cornelius had been complicit in the attempted assassination-if Thalius was the only dupe.

Tarcho had made good the Emperor's promise that Audax would have the chance to try life as a soldier. At the age of sixteen he was enlisted into the frontier garrison at Banna. He immediately flourished under the healthy food, medical supervision and training regime of the army; by the time he was eighteen he had shed the last shadow of the pale-as-a-ghost slave boy Thalius had dug up from the mine.

But he had rapidly proved too effective to be wasted in the stasis of a frontier post. On a letter of recommendation from Banna's commander, Audax was transferred away to the field army units in Gaul. Thalius saw him only rarely after that.

Audax was too young to fight in Constantine's first serious engagement with Licinius, Emperor of the east. It was a partial victory for Constantine; Licinius ceded territory but survived. The showdown came ten years after Constantine's visit to Britain, and by now Audax was old enough to serve.

'It was magnificent, Thalius,' he said now. 'They say it was the largest war for a century-there were perhaps a hundred and fifty thousand men on each side, and it raged across Europe and Asia for a year before Constantine's
