We flinched, our eyes on the blade, where the light slid with evil intent as the King slashed indiscriminately at the space before him. Our father was known to lash out at those nearest to him when the mood was on him, and we were not encouraged even when the servant removed the knife from our father’s hand—no cleaner than mine—and tucked the weapon into his own belt. Our father’s eyes were alight with a strange, knowing gleam. Unperturbed when I shrank away, he stretched out his hand to lift a lank curl of my hair from where it clung against my neck in matted hanks, like the fleece of a sheep after a long winter. His fingers tightened and I tensed all my muscles, waiting for the pain when he forgot his strength.

‘Which one are you?’ he asked, gently enough.

‘Katherine, Sire.’

‘Yes, you would be. You are very small.’ He quirked a brow. ‘And you?’

‘Michelle, Sire.’

‘Why are you not at your lessons?’

I slid a glance at Michelle, who simply hung her head. There had been no one to teach us anything for at least a month.

‘Well?’ A familiar harshness again coloured his demand. ‘Cat got your tongue?’

‘Madame, our governess, has gone away,’ I ventured.

‘Has she? Who dressed you this morning? No, don’t bother to answer that.’ The fire in his eyes dimmed as he swung round to address the servant. ‘Why are they like this? Little better than animals?’

‘There is no one, Sire.’

‘Why not? Do they not have their own household? Where are their servants?’

‘They too have gone, Sire. They have not been paid for many weeks now.’

The King bent his stare on me. The rapid blinking was unnerving but his question was both lucid and clear. ‘What are you hiding behind your back, Katherine?’ And when I showed him, he seized my hand and growled, ‘When did you last eat—apart from that?’

‘Yesterday, Sire.’ It was Michelle who answered. Words were beyond me in my fright.

‘And you stole the bread and meat? Be silent, both of you!’ the King roared before we had even begun to make our excuses, and we were silenced. ‘Before God! You’re no better than gutter urchins from the Paris stews! I should have you whipped.’

I sidled up to Michelle and clutched at her skirts, almost faint in my terror. Would our father truly beat us for our sin? I let the bread and meat fall to the floor as the trembling in my limbs became uncontrollable. I was never a brave child.

‘Where is their mother?’ he demanded. The servant shook his head. ‘Wait here!’

The King marched from the room, leaving the three of us an uneasy trio. What if he never came back? What if he forgot about us? Yet, indeed, it might be to our advantage if he did. I glanced at Michelle. Should we escape while we had the chance? She shook her head, and so we remained, listening to his footsteps fading into the distance. A little silence fell, broken only by my feet scuffing the floor and Michelle sniffing. The servant sighed heavily. And then in the distance footsteps returned. Our father strode back through the door, bringing a gust of wild, unfettered energy as he circled his arms like the sails of a windmill.

I whimpered.

‘Here!’ He thrust a goblet, heavy with gold and the glimmer of precious stones, into the servant’s hand. ‘Sell it!’ the King snarled with a show of uneven, discoloured teeth. ‘Pay a servant to tend to them. They need food and garments, fitting for my daughters.’ He stared down at us for a brief moment, puzzlement in his face, before marching once more from the room.

We were duly fed. I don’t recall if we were given new clothes.

So that is what I remember, the most vivid memory of my childhood. The cold, the hunger, the deprivation and neglect. The constant fear. The stark misery, product of the heedlessness of those who were set to care for us. Were Valois princesses allowed to suffer from misery? We were. We wallowed in it. For a little time matters improved for us, but how long could the coin raised by the sale of one gold cup last? Within a matter of weeks the coin had slipped into the hands of the servants and we were as starving and filthy as before as we roamed the palace like lost souls, bellies clapped hard against spines.

Who were we, Michelle and I? Was it accepted that Valois princesses should be raised in such squalor? Even though we were daughters of King Charles and Queen Isabeau, there was no one to plead our cause. Michelle and I were part of a vast family, of six brothers and five sisters, offspring of that most puissant King Charles VI of France and his even more powerful wife, Queen Isabeau of Bavaria.

Vastly fruitful in their marriage, the King and Queen were now estranged beyond repair. We, the younger children, trapped between them, became the victims of their hatred. My brothers were all dead, except for baby Charles, my sisters wed or had taken the veil, and Michelle and I were left to survive the shocking detachment of both parents.

Why should they care so little?

That was easy to understand as we grew older. The King our father suffered from an indisposition, increasing in virulence, that robbed him of his wits. He swung from incomprehension to lucidity, from violence to grinning insouciance, with terrifying regularity. In his worst moments he detested the Queen, hurling abuse and blows indiscriminately. As a wife who shared his bed and his Court, he had cast her off entirely. Some whispered that he had every right.

What scandal reached our ears, with its burden of sin and depravity.

For our mother, robbed of a husband who could be guaranteed to know her name, kept a separate court from our father, where she entertained a procession of lascivious amours. I might be young but the gossip was ribald and indiscreet, the innuendo clear enough to be within my understanding. I might lack a pair of shoes that were not worn through, but the Queen spent money with a lavish hand on her clothes and her courtiers, enjoying a life full of affairs of passion that horrified the courts of Europe.

A woman of outrageous physical need, it was said that she lured an endless stream of handsome, well-born men to warm her sheets. Even, it was whispered, my own father’s young brother, Louis of Orléans—until he was done to death by assassins under the orders of John the Fearless, my father’s Burgundian cousin. My own little brother Charles, the Dauphin since his brothers’ deaths, it was whispered, might not be my father’s son.

These were my parents, I their daughter Katherine. What an inheritance for a young girl to shoulder. Madness on one side, wanton lewdness on the other. The lurid rumours filled my young mind. Would I become like Charles and Isabeau? Would I inherit my parents’ natures, as I had inherited my mother’s fair hair?

‘Will I be mad and wicked too?’ I whispered to Michelle, naïve and afraid, appalled at the prospect that I would be pointed at, sneered over, ridiculed. I could not bear that.

‘I don’t see why you should,’ she pointed out with good common sense. ‘Our sister Marie was born pious—and smug about it. Why else would a woman take the veil? I have no intention of running amok or stripping to my shift for every man I see. Why do you think you should be tainted with our family shortcomings?’

This comforted me a little, until hunger and neglect forced me once more to acknowledge that my life, my hopes and fears, had no meaning for anyone. Isabeau’s reputation might paint her a woman of heat and passion, but none of it ever overlapped into maternal warmth. With the King enclosed in his chambers, and the Queen engaged in her own pursuits, Michelle and I survived as best we might, like the animals that the King had called us.

Until without warning our mother, Queen Isabeau, descended. It was not a happy reunion.

‘Holy Mother of God!’

My mother the Queen took one look at us. Even she, after her initial outburst, was silenced. Keeping her distance from the lice and squalor, she issued orders in a tone that brooked no disobedience. We were swept up, as if we ourselves were despised vermin, bundled into cloaks as filthy as we were and packed into a litter. The Queen, understandably, travelled separately and luxuriously in an eye-catching palanquin, whilst Michelle and I huddled in our hard carriage, cold and frightened, shivering with fear like a pair of terrified mice since no one had bothered to tell us of our destination. In this manner we, the two youngest of the Valois princesses, were delivered to the convent at Poissy.

‘These are the last of my two daughters. I leave them with you. They have sore need of discipline,’ the Queen announced on arrival.

It was after dark and the sisters were preparing to attend Compline, so there was no welcome for a child. I was frightened into silence. The figures in their white tunics and scapulars were ghostly, the Dominican black veils and cloaks threatening to my mind. My sister, smug and pious Marie, might already have taken her vows and be one of these shadowy beings but, so much older than I, I did not know her.

‘This is Michelle,’ the Queen continued. ‘Her marriage is arranged to Philip of Burgundy. Do what you can with her.’

I clutched Michelle’s hand, my fears multiplying at the thought of being alone with these magpie-clad creatures in so cold and bleak a place. How could I survive here, alone, when Michelle left to marry? My great-aunt, Marie of Bourbon, Prioress of Poissy, eyed us with chilly hauteur, much like one of my father’s raptors.

‘They are filthy.’ Supercilious, fastidious, her pale eyes flitted over us, disapproving. ‘And this one?’

‘This is Katherine. She is five years or thereabouts.’ Isabeau did not even know my age. ‘All I ask is that she be clean and well mannered. Suitable for a bride. There must be some high-blooded prince who will look favourably on her in return for a Valois alliance.’

The Prioress looked at me as if it might be a task beyond her abilities. ‘We will do our best for her too,’ she announced. ‘Does she read? Write?’

‘Not that I am aware.’

‘She must be taught.’

‘Is it necessary? Such skills are irrelevant for her future role, and I doubt she has the mental capacity to learn. Look at her.’ The Queen was cruel in her contempt as I snivelled in terror, wiping my face on my sleeve. ‘She will be wed for her blood, not for her ability to wield a pen.’

‘You would have her remain ignorant?’

‘I would not have her made a pedant. As long as she can catch a prince’s eye and grace his bed, someone will take her.’

They talked over my head, but I understood the tone of it and cringed from the shame that I knew I must feel. And then, the arrangements at an end, Isabeau looked at me directly for the first time.

‘Learn obedience and humility, Katherine. Be a credit to your name. You will be whipped if you choose to run wild here.’

I looked at the floor.

‘If you are sullen, who will wed you, Valois or not? No husband wants a sullen wife. And without a husband you will remain here and take the veil with your sister Marie.’

Those were her final words. She left without touching me. I was not sullen, but how could I explain? I dreaded a life I did not know or understand.

I was taken to a cell with Michelle. I could not complain, for we were not separated and it was suitably if sparsely furnished. Were we not princesses? I was given instructions to lie down, not to speak but to go to sleep, to rise the next morning at the bell for Lauds before dawn. My life at Poissy would begin.

And so it did. I lacked for nothing materially in those years. I was scrubbed and fed and given a modicum of instruction, I attended the services and learned to sing the responses. I learned obedience and humility, but no confidence such as blessed Michelle. All in all, it was a life of mind-numbing monotony as the years passed, coupled with anxiety over the strange prince who would one day take me if I proved to be pretty enough and humble enough. It was a cold existence.

‘They have need of discipline,’ the Queen had said.

And that was what we got. No love. No affection. Great-Aunt Marie’s rule was uncompromising, so that living at Poissy for me was like being encased in a stone tomb.

‘Which sins have you committed this week, Katherine?’ the Prioress asked, as she did every week.

‘I broke the Greater Silence, Mother.’

‘On one night?’

‘Every night, Mother,’ I admitted, eyes on the hem of her fine habit.

‘And why did you do that?’

‘To speak to Michelle, Mother.’

Michelle was my strength and my comfort. My solace. I needed her in the dark hours when the rats pattered over the floor and the shadows encroached. I needed to hear her voice and hold tight to her hand. If I had no confidence as a child, I had no courage either.
