“I’m not sure that’s right.”

“Take it from me.”

“Did he say that?”

“Yes, as a matter of fact, he did.”

Their father joined in. “This is a marvellous opportunity, Merthin,” he said. “To build a palace for an earl!”

“Of course it is,” Merthin replied. “But a bridge for this town is at least as important.”

“Don’t be stupid,” his father said.

“I do my best not to be,” Merthin said sarcastically.

“The earl of Shiring is one of the great men of the land. The prior of Kingsbridge is a nobody, by comparison.”

Ralph cut a slice of goose thigh and put it in his mouth, but he could hardly swallow. He had been afraid of this. Merthin was going to be difficult. He would not take orders from their father, either. He had never been obedient, even as a child.

Ralph felt desperate. “Listen,” he said. “The earl doesn’t want the new bridge to be built. He thinks it will take business away from Shiring.”

“Aha,” said Gerald. “You don’t want to go up against the earl, Merthin.”

“Is that what’s behind this, Ralph?” Merthin asked. “Is Roland offering me this job just to prevent the building of the bridge?”

“Not just for that reason.”

“But it’s a condition. If I want to build his palace, I must abandon the bridge.”

Gerald said with exasperation: “You don’t have a choice, Merthin! The earl doesn’t request, he commands.”

Ralph could have told him that an argument based on authority was not the way to persuade Merthin.

Merthin said: “I don’t think he can command the prior of Kingsbridge, who has commissioned me to build this bridge.”

“But he can command you.”

“Can he? He’s not my lord.”

“Don’t be foolish, son. You can’t win a fight with an earl.”

“I don’t think Roland’s quarrel is with me, Father. This is between the earl and the prior. Roland wants to use me, as a hunter uses a dog, but I think I’d do better to stay out of the fight.”

“I think you should do what the earl says. Don’t forget, he’s your kinsman, too.”

Merthin tried a different argument. “Has it occurred to you what a betrayal this would be of Prior Godwyn?”

Gerald made a disgusted noise. “What loyalty do we owe the priory? It was the monks who forced us into penury.”

“And your neighbours? The people of Kingsbridge, among whom you’ve lived for ten years? They need the bridge – it’s their lifeline.”

“We are of the nobility,” his father said. “We’re not required to take into account the needs of mere merchants.”

Merthin nodded. “You may feel that way, but as a mere carpenter I can’t share your view.”

“This isn’t just about you!” Ralph burst out. He had to come clean, he realized. “The earl has given me a mission. If I succeed, he may make me a knight, or at least a minor lord. If I fail, I could remain a squire.”

Maud said: “It’s very important that we all try to please the earl.”

Merthin looked troubled. He was always willing to go head-to-head with their father, but he did not like to argue with Mother. “I’ve agreed to build the bridge,” he said. “The town is counting on me. I can’t give it up.”

“Of course you can,” Maud said.

“I don’t want to get a reputation for unreliability.”

“Everyone would understand if you gave the earl precedence.”

“They might understand, but they wouldn’t respect me for it.”

“You should put your family first.”

“I fought for this bridge, Mother,” Merthin said stubbornly. “I made a beautiful design, and I persuaded the whole town to have faith in me. No one else can build it – not the way it should be done.”

“If you defy the earl, it will affect Ralph’s whole life!” she said. “Don’t you see that?”

“His whole life shouldn’t depend on something like this.”

“But it does. Are you willing to sacrifice your brother, just for the sake of a bridge?”

Merthin said: “I suppose it’s a bit like my asking him to save men’s lives by not going to war.”

Gerald said: “Come, now, you can’t compare a carpenter to a soldier.”

That was tactless, Ralph thought. It showed Gerald’s preference for the younger son. Merthin felt the sting, Ralph could tell. His brother’s faced reddened and he bit his lip as if to restrain himself from a combative reply.

After a pause, Merthin spoke in a quiet voice that Ralph knew to be a sign that he had made up his mind irrevocably. “I didn’t ask to be a carpenter,” he said. “Like Ralph, I wanted to be a knight. A foolish aspiration for me, I know that now. All the same, it was your decision that I should be what I am. As things have turned out, I’m good at it. I’m going to make a success of what you forced me into. One day I’d like to build the tallest building in England. This is what you made me – so you’d better learn to live with it.”

Before Ralph went back to Earlscastle with the bad news, he racked his brains for a way to turn defeat into victory. If he could not talk his brother into abandoning the bridge, was there some other way he could get the project cancelled or delayed?

There was no point talking to Prior Godwyn or Edmund Wooler, he was sure. They would be more committed to the bridge even than Merthin, and anyway they would not be persuaded by a mere squire. What could the earl do? He might send a troop of knights to kill the construction workers, but that could cause more problems than it solved.

It was Merthin who gave him the idea. He had said that Jake Chepstow, the timber merchant who was using Leper Island as a store yard, was buying trees from Wales to avoid the taxes charged by the earl of Shaftesbury.

“My brother feels he must accept the authority of the prior of Kingsbridge,” Ralph said to Earl Roland on his return. Before the earl had time to get angry, he added: “But there may be a better way to delay the building of the bridge. The priory’s quarry is in the heart of your earldom, between Shiring and Earlscastle.”

“But it belongs to the monks,” Roland growled. “The king gave it to them centuries ago. We can’t stop them taking stone.”

“You could tax them, though,” Ralph said. He felt guilty: he was sabotaging a project dear to his brother’s heart. But it had to be done, and he quelled his conscience. They will be transporting their stone through your earldom. Their heavy carts will wear away your roads and churn up your river fords. They ought to pay.”

“They’ll squeal like pigs. They’ll go to the king.”

“Let them,” Ralph said, sounding more confident than he felt. “It will take time. There are only two months left of this year’s building season – they have to stop work before the first frost. With luck, you could delay the start of the bridge until next year.”

Roland gave Ralph a hard look. “I may have underestimated you,” he said. “Perhaps you’re good for more than pulling drowning earls out of rivers.”

Ralph concealed a triumphant smile. “Thank you, my lord.”

“But how shall we enforce this tax? Usually there’s a crossroads, a ford in a river, some place every cart has to pass through.”

“Since we’re only interested in blocks of stone, we could simply camp a troop of men outside the quarry.”

“Excellent,” said the earl. “And you can lead them.”

Two days later Ralph was approaching the quarry with four men-at-arms on horseback and two boys leading a string of packhorses carrying tents and food for a week. He was pleased with himself, so far. He had been given an impossible task and turned it around. The earl thought he was good for more than river rescue work. Things were looking up.

He was deeply uncomfortable about what he was doing to Merthin. He had lain awake much of the night recalling their childhood together. He had always revered his clever older brother. They had often fought, and Ralph had felt worse when he won than when he lost. They had always made friends afterwards, in those days. But grown-up fights were harder to forget.
