Secrets of the Dead

gives a small shake of his head.

He cups his sister’s chin in his hand and tips her head back. He stares into her eyes. No one sees what passes between them.

‘It’s my fault,’ declares Constantine. ‘He tricked us all – I should never have let you marry him. Go back to your husband and tell him I accept his surrender. His titles are forfeit, but he can have safe passage to Thessalonica. The palace there should make a comfortable home.’ A reassuring smile. ‘After all, you’re still my sister.’

Constantiana stands and makes a show of embracing Constantine, so limp she can barely get her arms around him. When she’s steadier, Constantine pushes her back a little and offers her his hand.

As she kisses it, I hear her say three words. ‘Tu solus Dominus.’ You alone are the Lord.

Constantinople – April 337

‘That was a good day,’ Constantine says. ‘Our work was done.’

‘And the next day the sun came up, and you had twice as many provinces to govern, and twice as much work.’

‘But we were free.’ He crosses the room and pulls a sheet off one of the statues. A bearded white face stares back at him. ‘Do you remember when we were children at Diocletian’s court? Lying awake, listening to the floorboards, asking ourselves if this was the night the murderers would come? Every night, I prayed to God I’d live to see the morning. I was so terrified, I used to make you sleep in my bed.’

‘They never did come.’

‘I thought that when I became sole Augustus, I’d never be afraid again.’ He peers into the statue’s face. ‘And every day since I’ve been terrified of losing it all.’

‘What was Alexander doing for you?’ I ask abruptly. Constantine frowns. He doesn’t want to be dragged back from the past.

‘He was writing a history. He thought if he laid out all the events of my life in order, he’d find some sort of pattern. God’s will.’

‘Nothing else?’ Constantine has his back to me, running his fingers through the folds of the saint’s marble cloak. ‘I looked in his bag, I saw what was in it. It was stuffed full of papers he’d collected. Not the sort of things you’d want to go in his book. In fact, I’d say you had as much motive as anyone to want him dead.’

‘Alexander was a diligent researcher. The more facts he had, the more accurately he would reveal the pattern of God’s purpose. I gave him access to every archive and library in this city. Every document.’

I remember the items I found on Alexander’s desk – the razor blade, the jar of glue. And suddenly it all fits.

‘He wasn’t writing history,’ I say. ‘He was rewriting it – and not in his book, but deep in the archives.’ Constantine turned to listen: I can see on his face I’m right. ‘Whatever shamed you, or discredited you, he could remove it for ever. Like a sculptor recutting a statue’s face into a new likeness.’

When his project’s complete, no one will be able to see the joins.

‘A better likeness.’ Constantine walks back to the centre of the room. ‘So many things I’ve achieved in my life. I found a broken world and gave it peace. The hydra of government that Diocletian left, I cut off its heads one by one until the beast was dead and all its evils gone. On the day the army acclaimed me Augustus in York, there were men dying agonising deaths, simply because they didn’t want to sacrifice to old gods nobody believed in anyway. I put a stop to that. I let the people worship as they pleased – I gave the empire a God who was strong enough and merciful enough to tolerate dissent, even error, without violence.’

I think of Symmachus’s slave somewhere in the palace basement. I imagine how he screamed.

‘Not without violence.’

‘Of course not.’ He’s agitated now. ‘We have to live in the world we have, not the world we’d wish for. If the work was easy, or painless, there’d have been no need for me. You, more than anyone, know what it cost.’

He leans forward on the altar, as if he can’t support his own weight any more. There’s something that needs to be said right now – a last chance to clear away the fog between us. This is the closest we’ve come to being honest in years. But I can’t speak.

‘I should be remembered for who I was.’ He’s almost pleading – though not with me. He’s speaking to eternity. ‘The things I achieved, not the price I paid. I deserve that much.’

He wants history to love him. ‘And you got Alexander to make sure of it.’

‘He knew everything – everything – and never judged me for it. That’s why I needed to know who killed him. That’s why I asked you.’

‘And then convicted the first convenient scapegoat?’

He’s more human, than I’ve seen him in years. ‘Haven’t you been listening? Don’t you understand?’

We’re not talking about Alexander and Symmachus any more. We face each other across the room, divided by the altar. The dying sun shoots shafts of crimson light into the air above us, and his twelve apostles bear blind witness. I know what I have to say.

But the words are hard. I weigh them, and the moment I do they’re like a boulder in my hand. I push, but it won’t move. I’m not Alexander. I can’t forgive him.

‘You united the empire. That will be your legacy.’

And? He waits for more, giving me every chance. When he sees there’s nothing, he gives a bitter laugh. ‘Didn’t you know? I’ve divided it between my sons. Claudius, Constantius and Constans will each inherit a third. Mundus est omnis divisus in partes tres.’ He laughs again, so desperate it sounds like he’s sobbing. ‘If only things had been different.’

If only things had been different. He can rewrite the past as much as he likes, but
