My sworn enemy’s brother looked at me nervously. ‘Is it true, lord?’

‘Yes,’ I said, ‘but not until King Edward dies.’

Æthelwulf had flinched when I told him that brutal truth. ‘But why?’ he asked. ‘Why kill my brother?’

‘Did you ask your brother why he wanted to kill me?’ I retorted angrily. ‘Don’t answer, I know why. Because he believes I killed your father, and because I’m Uhtredærwe the Pagan, Uhtred the Priest-Killer.’

‘Yes, lord,’ he said in a low voice.

‘Your brother has tried to kill Æthelstan,’ I said, ‘and he’s tried to kill me, and you wonder why I want to kill him?’ He said nothing to that. ‘Tell me what happens when Edward dies?’ I asked harshly.

‘I pray he lives,’ Æthelwulf said, making the sign of the cross. ‘He was in Mercia when I left, lord, but had taken to his bed. The priests visited him.’

‘To give him the last rites?’

‘So they said, lord, but he’s recovered before.’

‘So what happens if he doesn’t recover?’

He paused, unwilling to give the answer he knew I did not want to hear. ‘When he dies, lord,’ he made the sign of the cross again, ‘Ælfweard becomes King of Wessex.’

‘And Ælfweard is your nephew,’ I said, ‘and Ælfweard is a sparrow-witted piece of shit, but if he becomes king, your brother thinks he can control him, and he thinks he can rule Wessex through Ælfweard. There’s just one problem, isn’t there? That Æthelstan’s parents really were married, which means Æthelstan is no bastard, so when Edward dies there’ll be civil war. Saxon against Saxon, Christian against Christian, Ælfweard against Æthelstan. And long ago I swore an oath to protect Æthelstan. I sometimes wish I hadn’t.’

He stopped in surprise. ‘You do, lord?’

‘Truly,’ I said, and explained no further. I drew him on, pacing the long rampart. It was true I had sworn an oath to protect Æthelstan, but increasingly I was not certain that I liked him. He was too pious, too like his grandfather, and, I also knew, too ambitious. There is nothing wrong with ambition. Æthelstan’s grandfather, King Alfred, had been a man of ambition, and Æthelstan had inherited his grandfather’s dreams, and those dreams meant uniting the kingdoms of Saxon Britain. Wessex had invaded East Anglia, it had swallowed Mercia, and it was no secret that Wessex wished to rule Northumbria, my Northumbria, the last British kingdom where men and women were free to worship as they wished. Æthelstan had sworn never to invade Northumbria while I lived, but how long could that be? No man lives for ever, and I was already old, and I feared that by supporting Æthelstan I was condemning my country to the rule of southern kings and their grasping bishops. Yet I had sworn an oath to the man most likely to make that happen.

I am a Northumbrian and Northumbria is my country. My people are Northumbrians, and Northumbrians are a hard, tough people, yet we are a small country. To our north lies Alba, full of ambitious Scots who raid us, revile us, and want our land. To the west lies Ireland, home to Norsemen who are never satisfied with the land they have, and always want more. The Danes are restless across the eastern sea, and they have never relinquished their claim to my land where so many Danes have already settled. So to the east, to the west, and to the north we have enemies, and we are a small country. And to the south are Saxons, folk who speak our language, and they too want Northumbria.
