Henry is dressed handsomely in dark green velvet with dark green leather riding boots and green leather gloves. He is trying so hard to look like a king living on his own fortune, comfortable with his court, happy in his kingdom, beloved of his people. Only the new lines around his pinched mouth betray him as a man living with gritted teeth.

We are near the open gate of Woodstock Palace when I hear hooves on the road and turn to see a hard-ridden horse and the rider bowed over his neck urging him on. The yeomen of the guard at once gather before the king and six of them turn and stand in a line before me, and I observe, amazed, that they are shouldering their arms and then grounding their pikes. They have seen a single man riding as fast as he can towards our palace and they are readying for an attack. They actually think that a man might ride up to our court as we prepare to go hawking, and cut down Henry, King of England, where he stands. They actually think that they have to stand between me and any subject of this kingdom. I see their fear and I realize that they know nothing of what it is to be a queen of the House of York.

They hold their pikes firm, in a line of defense, as the man hauls on his reins and his weary horse skids almost to a halt and then walks towards us. “Message for the king,” he says, hoarse with the dust in his throat, as Henry recognizes his messenger, puts a hand on one of his beefeaters’ shoulders, turns him away, and approaches the shivering horse and the exhausted rider.

The man jumps from the saddle, but he is so weary that his legs buckle beneath him and he has to grab on the stirrup leather to keep himself up. He puts a hand inside his jacket and pulls out a battered sealed packet.

“Where from?” Henry asks quietly.

“Cornwall. The very far west of Cornwall.”

Henry nods and turns to the court. “I must stay and read this,” he calls. His voice is determinedly light, the smile he is straining to show them all is a grimace, like a man in pain. “A little business, nothing but a little business must detain me. You go on, I’ll ride after!”

People murmur and mount up, and I gesture to my groom to hold my horse as I stand beside Henry and watch them go by. As the hawk cart goes past us, one of the falconers is tying the leather curtains to keep the birds cool and clean till they get to the fields where the hunt will start; then they will take the hoods off and the hawks will mantle their wings and look about them with bright eyes. One of the lads is running behind, carrying spare jesses and leashes. I glimpse his face when he ducks his head in a bow as he goes past the king: Lambert Simnel, promoted from his place as scullery boy, now a royal falconer, loyal in the king’s service—a pretender who has found happiness.

Henry does not even see him. He does not see anybody as he turns and goes into the east door that leads up the great stairs to his presence chamber. I follow, and there is his mother, waiting in his rooms, watching from the window. “I saw the messenger coming from far away,” she says to him quietly, like a woman waiting for the worst news in the world. “I have been praying since the moment I saw the dust on the road. I knew it was the boy. Where has he landed?”

“Cornwall,” he answers. “And I have no friends in Cornwall now.”

It is pointless to tell him that he has no friends in Cornwall now since he broke their pride, and broke their hearts, and hanged the men that they loved and followed. I wait in silence as Henry rips open the wrapping of the letter and takes out the paper. I see the seal of the Earl of Devon, William Courtenay, my sister Catherine’s husband, and the father of her adored son.

“The boy has landed,” Henry says, reading rapidly. “The Sheriff of Devon attacked his camp with a strong force.” He pauses; I see him take a breath. “The sheriff’s men all deserted and went over to the boy as soon as they saw him.”

Lady Margaret presses her hands together as if she is praying but says nothing.

“The Earl of Devon, my brother-in-law.” Henry looks at me as if I am responsible for William Courtenay. “The Earl of Devon, William Courtenay, was going to attack himself but thought they were too strong and he could not trust his men. He’s fallen back to Exeter.” He lifts his head. “The boy has just landed and already he has all of Cornwall and much of Devon; and your brother-in-law has fallen back to Exeter because he cannot trust his men to stay true to him.”

“How many?” I ask. “How many men does the boy have?”

“About eight thousand.” Henry gives a mirthless bark of a laugh. “More than I had, when I landed. It’s enough. It’s enough to take the throne.”

“You were the rightful heir!” his mother says passionately.

“The Earl of Devon, William Courtenay, is trapped in Exeter,” Henry says. “The boy has set a siege.” He turns to his writing table and shouts for clerks. His mother and I step back as the men run into the room and Henry gives orders. Lord Daubney is to march towards the boy’s forces, and relieve William Courtenay in Exeter. Another army commanded by Lord Willoughby de Broke is to hold the south coast so that the boy cannot get away. Every lord in the country is commanded to raise men and horse and meet Henry to march on the West Country. They must all come, there can be no excuses.

“I want him brought to me alive,” Henry says to each of his clerks. “Write that to each commander. He must be taken alive. And tell them to fetch his wife and son too.”

“Where are they?” I ask “His wife and his son?” I cannot bear the thought of the young woman with her baby, the young woman who may be my sister-in-law, in the midst of an army setting a siege.

“St. Michael’s Mount,” Henry says briefly.

My Lady the King’s Mother gives an irritated exclamation at the thought of the boy and his son weaving themselves into the story of Arthur, a legend she has tried so hard to attach to our boy.

The clerks hand over the orders, dripping with hot wax, and Henry stamps them with his seal ring and signs with a spiky up-and-down scratch of the pen HR: Henricus Rex. I think of the proclamation that I saw signed with RR: Ricardus Rex, and know that once again there are two men who claim to be king treading the soil of England, once again there are two rival royal families, and this time I am divided between the two.

We wait. Henry cannot bring himself to go hawking, but sends me out to dine in the tents in the woods with the hunters and to play the part of a queen who thinks that all is well. I take the children with me on their little ponies, and Arthur on his hunter rides proudly at my side. When one of the lords asks me if the king is not coming I say that he will come in a while, he was detained by some business, nothing of importance.

I doubt very much that anyone believes me. The whole court knows that the boy is somewhere off our coasts; some of them will know that he has landed. Almost certainly, some of them will be preparing to join him, they may even have his letter of array in their pockets.

“I’m not afraid,” Arthur tells me, almost as if he is listening to the words and wondering how they sound. “I am not afraid. Are you?”

I show him an honest face and a genuine smile. “I’m not afraid,” I say. “Not at all.”

When I get back to the palace there is a desperate message from Courtenay. The rebels have broken in through the gates of Exeter, and he is wounded. With the walls breached, he has made a truce. The rebel army has been merciful, there has been no looting, they have not even taken him prisoner. Honorably, they release him and in return he has allowed them to go on, along the Great West Way, heading for London, and he has promised he will not pursue them.

“He let them go?” I ask disbelievingly. “To march on London? He promised not to pursue them?”

“No, he’ll break his word,” Henry says. “I will order him to break his word. A promise to rebels like that need not be kept. I’ll order him to trail behind them, block their retreat. Lord Daubney will come down on them from the north, Lord Willoughby de Broke will attack from the west. We will crush them.”

“But he made a promise,” I say uncertainly. “He has given his word.”

Henry’s face is dark and angry. “No promise given to that boy counts before God.”

His servants come in with his hat, his gloves, his riding boots, his cape. Another goes running to the stables to order his horses, the guard is mustering in the yard, a messenger is riding for all the guns and cannon that London has.

“You’re going to your army?” I ask. “You’re riding out?”

“I’ll meet with Daubney and his army,” he says. “We’ll outnumber them by three to one. I’ll fight him with odds like these.”

I catch my breath. “You’re going now?”

He kisses me perfunctorily, his lips cold, and I can almost smell the scent of his fear. “I think we’ll win,” he says. “As far as I can be certain, I think we’ll win.”

“And what will you do then?” I ask. I dare not name the boy and ask what Henry plans for him.

“I will execute everyone who has raised a hand against me,” he says grimly. “I will show no mercy. I will fine everyone who let them march by and did not stop them. When I have finished, there will be no one left in Cornwall and Devon but dead men and debtors.”

“And the boy?” I ask quietly.

“I will bring him into London in chains,” he says. “Everyone has to see that he is a nobody, I will throw him down into the dust and when everyone understands at last that he is a boy and no prince, I will have him killed.”

He looks at my white face. “You will have to see him,” he says bitterly, as if all of this is my fault. “I will want you to look him in the face and deny him. And you had better make sure that you say no word, give no look, not a whisper, not even a breath of recognition. Whoever he looks like, whatever he says, whatever nonsense he spouts when he is asked: you had better be sure that you look at him with the gaze of a stranger, and if anyone asks you, you don’t know him.”
