She turns to me. ‘So Isabel did nothing for us, though we sent her ahead to be with her husband. She didn’t keep George to our alliance,’ she says spitefully. ‘I will remember this. You had better remember this. She failed to keep him faithful to you, to me, to your father. She is a poor daughter and a poor wife, a wretched sister. I think she will regret this. I will make sure that she regrets the day her husband betrayed us.’

‘My father?’ I whisper. ‘Is my father coming now?’

I see the Duke of Somerset wince and look at the queen for permission to speak.

‘My father?’ I ask more loudly. ‘What of my father?’

‘He died in the battle,’ he says quietly. ‘I am sorry, my lady.’

‘Died?’ she demands baldly. ‘Warwick is dead?’

‘Yes.’

She starts to smile, as if it is funny. ‘Killed by Edward?’

He bows in assent.

She cannot help herself. She lets out a peal of laughter, clapping her hand over her mouth, trying to silence herself but not able to cease laughing. ‘Who would have thought it?’ she gasps. ‘Who would ever have thought such a thing? My God! The wheel of fortune – Warwick killed by his own beloved protégé! Warwick against his own wards and they kill him. And Edward with his two brothers at his side again – after all we have done and sworn . . .’ Slowly she subsides. ‘And my husband, the king?’ She moves onto the next question as if there is nothing more to be said about the death of my father.

‘How did he die?’ I ask, but nobody answers me.

‘The king?’ she repeats impatiently.

‘Safe in London, back in the Tower. They picked him up after the battle and took him as their prisoner.’

‘He was well?’ she asks quickly.

Somerset shifts uncomfortably. ‘Singing,’ he says shortly. ‘In his tent.’ The mad king’s son and his wife exchange one brief look.

‘Did my father die in battle?’ I ask.

‘The York brothers went back to London victorious, but they will rest and arm and come on here,’ Beaufort warns her. ‘They will have heard that you have landed, just as we did. They will be marching after us as fast as they can come.’

She shakes her head. ‘Ah, dear God! If we had only come sooner!’

‘George Duke of Clarence might still have proved untrue. The Earl of Warwick might still have been killed,’ the duke says steadily. ‘As it is, your coming now brings us a fresh army, newly landed, and people gathering to support you as a new cause. Edward has marched, and fought, and is now marching again. He has drawn on all his credit, he has been joined by all his friends, there is no-one left to recruit and they have fought a heavy battle and suffered losses, and they are all tired. It was a hard battle and a long march. Everything is in our favour.’

‘He’ll be coming here?’

They all nod; there is no doubt that the House of York is coming to the table for a final throw of the dice.

‘For us?’

‘Yes, Your Grace – we have to move out.’

For a moment she draws a breath, then she makes a small gesture with her hand, drawing a circle in the air. ‘The wheel of fortune,’ she says almost dreamily. ‘Just as Jacquetta said. Now her son-in-law is coming to attack me, having killed my ally; and her daughter and my son are rivals for the throne and she and I are far apart. I suppose we are enemies.’

‘My father . . .’ I say.

‘They took his body to London, Your Grace,’ the duke says quietly to me. ‘Edward captured his body, and also that of your uncle Lord Montagu. I am sorry, Your Grace. He will show the bodies to the people of London, so that everyone knows he is dead and his cause lost.’

I close my eyes. I think of my grandfather’s head on the spike on the walls of York, put there by this queen. Now my father’s dead body will be put on show to the people of London by the boy who loved him like a brother. ‘I want my mother,’ I say. I clear my throat and say it again: ‘I want my mother.’

The queen hardly hears me. ‘What do you advise?’ she asks Edmund Beaufort.

I turn to my husband, the young prince. ‘I want to be with my mother,’ I say. ‘I have to tell her. I have to tell her of the death of her husband. I must go to her. I must find her.’

He is listening to the duke; he barely glances at me.

‘We have to march north and west, join up with Jasper Tudor in Wales,’ the duke replies to the queen. ‘We have to go at once, get ahead of Edward. Once we join with Tudor’s forces in Wales, we can come back into England in strength and attack Edward at a place of our own choosing. But we have to recruit men.’

‘We should go now?’

‘As soon as you are ready to travel. We need to start the march. Edward always travels fast, and so we need to be ahead and stay ahead of him. We have to get to Wales before he can cut us off.’

I see her change at once, from a woman receiving a warning into the commander who will drive the march. She has ridden at the head of an army before now, she has taken an army into battle. She responds to the call to action, she is quite without fear. ‘We are ready! Order the men. They have disembarked and eaten and drunk, they are ready to march. Tell them to fall in.’

‘I need to see my mother,’ I say again. ‘Your Grace, I need to see my mother, she may not even know of the death of her husband. And I need to be with her.’ Like a child my voice quavers. ‘I have to go to my Lady Mother! My father is dead, I have to go to my mother.’

At last she hears me. She glances at Edmund Beaufort. ‘What of Her Grace the Countess of Warwick?’

One of his men comes in and whispers to him and he turns to me. ‘Your mother has been told of the death of her husband. Her ship made landfall down the coast, and the men who were on board are just joining us now. They say they had the news in Southampton of the battle. She was told.’

I get to my feet. ‘I must see her. Excuse me.’

‘She did not come with the men.’

Queen Margaret clicks her tongue in irritation. ‘Oh, for God’s sake! Where is she?’

The messenger speaks to the duke again. ‘She has retired to Beaulieu Abbey. She has sent word to say that she will not ride with you. She says she has taken sanctuary.’

‘My mother?’ I cannot understand what they are saying. ‘Beaulieu Abbey?’ I look from the duke to the queen and then to my young husband. ‘What am I to do? Will you take me to Beaulieu Abbey?’

Prince Edward shakes his head. ‘I can’t take you. There’s no time.’

‘Your mother has abandoned you,’ the queen says flatly. ‘Don’t you understand? She is in hiding in fear of her life. Clearly she thinks that Edward is going to win and we will be defeated and she doesn’t want to be with us. You will have to come with us.’

‘I don’t . . .’

She rounds on me, her face white with fury. ‘Understand this, girl! Your father has been defeated, his army all but destroyed. He is dead. Your sister cannot keep her husband on our side. Your mother has hidden herself away in an abbey. Your influence is worthless, your name means next to nothing. Your family do not stand by you. I have bound my son in marriage to you thinking that your father would defeat Edward but it is Edward who has defeated him. I thought your father was the man to destroy the House of York – the kingmaker as they call him! – but his protégé turns out to be the better man. Your father’s promises are empty, your father is dead. Your sister is a turncoat and your mother has tucked herself up safely in sanctuary, while we fight for our lives. I don’t need you, you can do nothing for me. I don’t want you particularly. If you want to go to Beaulieu Abbey you can go. You mean nothing to me. Go to Beaulieu Abbey and wait to be arrested as a traitor. Wait for Edward’s army to come in, and rape you with the rest of the nuns. Or ride with us with the chance of victory.’

I am trembling at her sudden rage.

‘You can decide,’ her son says indifferently, as if I am not his wife, bound to be with him. ‘We can send a couple of men to ride with you. Later, we can get the marriage annulled. What do you want to do?’

I think of my father, dying to put me on the throne, fighting against an army that came out of the mist. I think of his burning constant ambition that a Neville girl should take the throne of England, that we should make a king. He did that for me. He died for me. I can do this for him. ‘I’ll come,’ I say. ‘I’ll come with you.’

We set off on a punishing march, men flocking to our standards every time we halt. The queen is beloved in the western counties and her friends and allies have long promised that she would land on their shores and lead an army against the House of York. We go north and west. The city of Bristol supports us with money and cannon, and the citizens pile out into the narrow streets with their caps filled with gold coins for us. Behind us, Edward has to recruit soldiers on the run, in a country that has no love for the House of York. We hear that he finds it hard going and is lacking the support he needs; his army is tired, and every day the gap between our forces widens as we get away from him. Our spies tell us that he is falling behind, delayed by the need to get more men, incapable of catching us. Margaret laughs and jumps down from the saddle at the end of the day like a girl. I climb down wearily, aching all over, my knees and my buttocks red and sore.
