How easy it was to make that decision, and to inform John of my wishes, refusing any advice to the contrary. My energy restored with the prospect of action, I marched to Young Henry’s room, swept the baby up from his cradle and took him to look out of the window in the general direction of where his father might be at that very moment. Young Henry was growing, I noticed. He was heavier in my arms now.

‘Shall we go to France? Shall I take you to see your father?’

He grinned with toothless gums. ‘Then we will go.’

But first, before I saw Henry again, I knew I must discover the truth to some unanswered questions. After months of inactivity, I was swept with a desire to discover what was hidden, and perhaps to build some bridges.

It was not at all what I had expected when, accompanied by an impressive escort, including both Gloucester and Bishop Henry, I made a bid to discover all I could about Henry’s imprisoned stepmother and the troubling prophecy.

Leeds Castle, a beautiful little gem set in a sapphire lake created by two encircling arms of a river, the waters reflecting the blue of the sky, was no grim dungeon for Madam Joanna. A soft imprisonment—yet still, all in all, it was an imprisonment if she lived under the custody of Sir John Pelham, as Bishop Henry informed me, and was not free to travel. I was both intrigued and anxious. What would this visit reveal about Madam Joanna—or indeed about Henry?

We were announced into her chamber: Joanna of Navarre, Queen Dowager of England and second wife of Henry’s father. She did not rise from her chair when Gloucester and Bishop Henry kissed her cheeks with obvious fondness. And I saw why she did not stand when she placed an affectionate hand on Gloucester’s sleeve.

Elegant she may be, her pure white hair coiffed, the folds of her houppelande rich with embroidered panels, jewels gleaming at neck and wrist, but her hands were crippled into claws and her shoulders rigid, and any movement deepened the lines between her brows. Discomfort notwithstanding, I was welcomed with a smile and a speculative regard from direct grey eyes. Entertained with music and wine, Gloucester and Bishop Henry proceeded to enliven her existence with news of court trivia and some comment on what Henry was doing in France.

Madam Joanna absorbed it all, then announced with quiet authority: ‘I wish to speak with Katherine.’ And when we were alone, duke and bishop obediently departing: ‘Sit next to me. I hoped you would come and visit me.’

I moved to the stool at her side. ‘I did not realise, my lady.’ What a poor excuse it sounded even to my ears, and what an appalling situation. ‘I did not even know—’

‘That I was a prisoner.’ She completed my thought with astonishing complacence.

‘Henry told me you chose to live a quiet life.’

‘Perhaps I would, in the circumstances.’ She lifted her arthritic hands with a little moue of distaste, before allowing them to fall gently back into her lap. ‘But this is no choice.’ Her smile was wry and humourless, her eyes sharp, demanding an honest response. ‘And no doubt you wish to know why my stepson keeps me under lock and key?’

‘Mistress Waring said that…’ How could I voice something so terrible?

‘I was accused of witchcraft.’ Madam Joanna frowned as if the words pained her. ‘It is true. So I am accused. Do you believe it?’

‘I don’t know. I don’t think Bishop Henry does. Or Gloucester.’ Their warm acknowledgement of the Queen Dowager, their affection for her, could not be ignored.

‘I don’t think Henry believes it either,’ Madam Joanna added dryly. ‘But he needed me to be vulnerable.’

Again, I was lost for words. ‘But why?’

‘So that he could confiscate my dower lands and income, of course.’ Her candid explanation startled me, even more her calm acceptance of it. ‘England needed as much gold as she could raise in order to pursue the French wars. The easiest source to plunder was my dower. So how to get his hands on it? It was so simple. He had me accused of threatening his life with necromancy.’

‘But that’s despicable.’

‘I cannot disagree. And—do you know?—I have never been put on trial. I have been unfairly accused and incarcerated for more than two years in one castle or another.’

It was too much for me to take in. ‘I can’t believe that he would do that.’

‘How long have you lived with Henry? Have you not yet learnt that he can be ruthless?’ Madam Joanna’s smile and voice acquired an edge worthy of a honed sword. ‘Where do you think he got the money for your dower?’

If I was horrified before, now I was shocked almost into disbelief. It was a shattering revelation, undermining all my pleasure in what I had once considered to be Henry’s true consideration for me.

To compensate for my lack of a dower in gold coin, Henry had provided me with the vast sum, to my eyes, of a hundred thousand marks to spend every year, as well as gifting me lands and estates, manors and castles, put aside for my own personal use. Henry had ensured that I was not a penniless supplicant, and once I had marvelled at his generosity. Now I learned that it was at the expense of this tragic lady.

‘My dower was exploited and I remain under duress until Henry decides to free me.’ Madam Joanna tilted her chin, wincing a little. ‘I’m not sure I can ever forgive him for that.’

I could think of nothing to say that would assuage my guilt or add to Madam Joanna’s comfort. Her situation was truly deplorable. All I could manage was, ‘I am so sorry.’

‘Why should you be? It was not your doing. Henry needed to fund your dowry, and mine was the obvious source. He is a man driven to reclaim the possessions of his ancestors and ensure England’s greatness,’ Madam Joanna continued. ‘The French war and England’s victory is his only concern.’

‘I know it is,’ I murmured. ‘Do you think I have not seen it for myself?’ It seemed disloyal to admit it, but Madam Joanna’s plain speaking encouraged me.

Seeing my unease, Madam Joanna leaned to close her hand awkwardly over mine. ‘That is not good. You should go to your husband,’ she said, as if reading my thoughts. ‘It is almost a year now, is it not, since you last saw him? I know Henry very well, and I know that you should be with him. He allows his mind to be taken up with the here and now—and sometimes he needs to be reminded that there are other people who need his attention.’

‘But I don’t think he wants me with him.’ For the first time I confessed my fears aloud, seduced by the compassion in this gentle woman. ‘He does not love me, you see. He never has…’

Her brows lifted. ‘How could he not love so beautiful a wife as you?’

‘He never pretended that he did. I thought he did, and I was naïve enough to think that he might. He was kind and chivalrous, you see.’

Her hands tightened imperceptibly. ‘You poor girl. How could you know what was in his mind? I never could. As a young man he never permitted anyone to see what was important to him—almost in case it was snatched away and he lost it. And he has excellent manners. How does one read what he is thinking behind that impossible facade of dignified control? I don’t suppose he has changed.’

Madam Joanna paused, then urged, her voice no longer soft, ‘Go to him. If you wish to make anything of your marriage other than a distant circling of minds that never meet and have no understanding of each other, go and be with him in France. It’s too dangerous to take the young boy, but Mistress Waring will care for your child. She will let no harm come to him.’

‘Yes. I will.’ It seemed such wise advice, such an intuitive reading of my life and Henry’s. And such solace to my heart that I was not the only one to be misled by Henry’s excellent manners.

‘Make him notice you. Beguile him. Lure him from the battlefield, if only for a little while.’ She smiled with a touch of very female mischief, which sat oddly on her weary features but hinted at her charm as a young woman. ‘It should not be beyond a beautiful woman.’

Yes, Madam Joanna was wise indeed. Perhaps if Henry and I were to live together again, away from battlefields and campaigns, we could build a closeness, an understanding. Perhaps he would even grow to have an affection for me. Were not all things possible with God’s grace?

‘I will do it.’ The resolve settled in my belly.

She patted my hand carefully. ‘Henry, I am certain, does know what a jewel he has in you. You are still young, with all your life before you. All you have to do is remind him and bring him home to England once in a while.’ We smiled our understanding. ‘And now I expect you must go. Your escort will be champing at the bit and damning gossiping women to the very devil. But you must come again. Sometimes I am lonely.’

This brought to my mind what had been hovering over my head during the entire visit.

‘Mistress Waring said I should ask you about a prophecy,’ I said.

‘Did she?’ Madam Joanna’s all but invisible brows drew down into a line.

‘I gave birth to my son at Windsor. Henry forbade it and Mistress Waring disapproved. Henry gave no reason but Mistress Waring said there was a prophecy…’

Madam Joanna’s features sharpened as she looked away beyond the window, to the scene of freedom denied. ‘I have no truck with such things, even though some would have me guilty of a far worse crime. But, yes, there was such a prediction made to poor Mary de Bohun who did not live to see her son grow to adulthood. A venomous little comment, I would say, product of some malicious mind that had no good thought for the House of Lancaster. It was told to me by Mary’s tirewoman in a moment of unedifying gossip over a cup of ale. From what you tell me, it seems that Henry too knows of the calumny from some source—I was not aware. Do you wish to know?’
