Lady Elizabeth’s entourage halted before us and Lady Mary started to dismount as Lady Elizabeth flung herself down from her horse as if she had been waiting all her life for this moment, as if she had never skulked in bed, biting her nails and wondering what would happen next. At the sight of her, the Lady Mary’s face lit up, as a mother will smile on seeing her child. Clearly, Elizabeth riding in her pride was a sight that gave her sister a pure unselfish joy. Lady Mary held out her arms, Elizabeth plunged into her embrace and Lady Mary kissed her warmly. They held each other for a moment, scrutinising each other’s faces and I knew, as Elizabeth’s bright gaze met Mary’s honest eyes, that my mistress would not have the skill to see through the fabled Tudor charm to the fabled Tudor duplicity which lay beneath.

Lady Mary turned to Elizabeth’s companions, gave them her hand and kissed each of them on the cheek to thank them for bearing Elizabeth company and giving us such a grand welcome into London. Lady Mary folded Elizabeth’s hand under her arm, and scanned her face again. She could not have doubted that Elizabeth was well, the girl was radiant with health and energy, but still I heard a few whispered confidences of Elizabeth’s faintness, and swelling of her belly, and headache, and the mysterious illness that had confined her to bed, unable to move, while the Lady Mary had stared down her own fear alone, and armed the country and prepared to fight for their father’s will.

Elizabeth welcomed her sister to the city and congratulated her on her great victory. ‘A victory of hearts,’ she said. ‘You are queen of the hearts of your people, the only way to rule this country.’

‘Our victory,’ Mary said generously at once. ‘Northumberland would have put us both to death, you as well as me. I have won the right for us both to take our inheritance. You will be an acknowledged princess again, my sister and my heir, and you will ride beside me when I enter London.’

‘Your Grace honours me too much,’ Elizabeth said sweetly.

‘She does indeed,’ Jane Dormer said in a hiss of a whisper to me. ‘Sly bastard.’

The Lady Mary gave the signal to mount and Elizabeth turned to her horse as her groom helped her into her saddle. She smiled around at us; saw me, riding astride in my pageboy livery, and her gaze went past me, utterly uninterested. She did not recognise me as the child who had seen her with Tom Seymour in the garden, so long ago.

But I was interested in her. From the first glimpse I had of her, up against a tree like a common whore, she had haunted my memory. There was something about her that absolutely fascinated me. The first sight I had of her was that of a foolish girl, a flirt, a disloyal daughter, but there was always more to her than that. She had survived the execution of her lover, she had avoided the danger of a dozen plots. She had controlled her desire, she had played the game of a courtier like an expert, not like a girl. She had become her brother’s favourite sister, the Protestant princess. She had stood outside the conspiracies of the court and yet known to a penny the price of every man. Her smile was utterly carefree, her laugh as light as birdsong; but her eyes were as sharp as a black-eyed cat that misses nothing.
