It is the court of a frightened pretender and there is no majesty or pride or confidence about it. Working alone, I can do nothing, when I process on my own to dinner with my head held high, smiling around at friends and suspects alike, trying on my own to overcome the impression that the king is afraid and his court are uncertain.

Then, one evening, John Kendal, the Bishop of Worcester, stops me on my way to my rooms with a kindly smile, and asks me, as a man offering to show a rainbow or a pretty sunset: “Have you seen the light from the beacons, Your Grace?”

I hesitate. “Beacons?”

“The sky is quite red.”

I turn to the arrow-slit window in the castle and look out. To the south the sky is quite rosy, and as far as I can see there is a light on a hill, and then another, and then another behind and behind one after another all the way until I can see nothing more.

“What is it?”

“The king commanded beacons to warn him of the landing of Richard of York,” John Kendal says.

“You mean the pretender,” I remind him. “The boy.”

In the glow of the lights I catch his hidden smile and I hear his low laugh. “Of course. I forgot his name. These are the beacons. He must have landed.”

“Landed?”

“These are his beacons. The boy is coming home.”

“The boy is coming home?” I repeat like a fool. It cannot be that I have mistaken the bishop’s delight in the rosy light of the beacons. He is illuminated with joy as if the beacons were welcoming flares to guide ships safely into port. He smiles at me to share his delight that the Plantagenet boy is homeward bound.

“Yes,” he says. “They are lighting his way home at last.”

Next day Henry thunders out of the castle surrounded by his guard, without a word of farewell to me, riding west to raise troops, visiting castles in the Stanley areas, desperate to keep them loyal, uncertain of them all. He does not even say good-bye to the children in the nursery or go to his mother for her blessing. She is horrified by his sudden departure and spends all her time on her knees on the stone floor of the chapel at Worcester, not even coming to breakfast, for she is fasting, starving herself to draw down a blessing on her son. Her thin neck at the top of her gown is red and raw, as she is wearing a hair shirt against her skin to mortify her paper-thin flesh. Jasper Tudor rides beside Henry, like a tired old warhorse that does not know how to stop and rest.

Confused rumors come back to us. The boy has landed in the east of the country, coming into England through Hull and York, as my father did when he returned in triumph from his exile. The boy is following in King Edward’s footsteps as his true son and heir.
