“Apparently the marriage was never consummated.”

“Is that all there is to it?”

“Probably. According to Gratian-a learned man whom I have met myself, actually-what constitutes a marriage is the mutual consent of the two parties; but he also maintains that the act of physical union ‘completes’ or ‘perfects’ the marriage. He specifically says that if a man marries a woman but does not copulate with her, then marries a second woman with whom he does copulate, then it is the second of the two marriages that is valid, that is to say, the consummated one. The fascinating Aliena will no doubt have mentioned this in her application, if she had sound advice, which I imagine she got from Prior Philip.”

William was impatient of all this theory. “So they will get the annulment.”

“Unless someone brings up the argument against Gratian. In fact there are two: one theological and one practical. The theological argument is that Gratian’s definition denigrates the marriage of Joseph and Mary, since it was unconsummated. The practical argument is that for political reasons, or to amalgamate two properties, marriages are quite commonly arranged between two children who are physically incapable of consummation. If either bride or groom should die before puberty, the marriage would be invalidated, under Gratian’s definition, and that could have very awkward consequences.”

William could never follow these convoluted clerical wrangles, but he had a pretty good idea of how they were settled. “What you mean is, it could go either way.”

“Yes.”

“And which way it goes depends upon who is putting pressure on.”

“Yes. In this case, there’s nothing hanging on the outcome-no property, no question of allegiance, no military alliance. But if there were more at stake, and someone-an archdeacon, for example-were to put the argument against Gratian forcefully, they would probably refuse the annulment.” Waleran gave William a knowing look that made William want to squirm. “I think I can guess what you’re going to ask me next.”

“I want you to oppose the annulment.”

Waleran narrowed his eyes. “I can’t make out whether you love that wretched woman or hate her.”

“No,” William said. “Nor can I.”

Aliena sat on the grass, in the green gloom beneath the mighty beech tree. The waterfall cast droplets like tears onto the rocks at her feet. This was the glade where Jack had told her all those stories. This was where he had given her that first kiss, so casually and quickly that she had pretended that it had never happened. This was where she had fallen in love with him, and refused to admit it, even to herself. Now she wished with all her heart that she had given herself to him then, and married him and had his babies, so that now, whatever else intervened, she would be his wife.

She lay down to rest her aching back. It was the height of summer, and the air was hot and still. This pregnancy was so heavy, and she still had at least six weeks to go. She thought she might be carrying twins, except that she felt kicking in only one place, and when Martha, Jack’s stepsister, had listened with her ear right up against Aliena’s belly she had heard only one heartbeat.

Martha was looking after Tommy this Sunday afternoon, so that Aliena and Jack could meet in the woods and be alone for a while to talk about their future. The archbishop had refused the annulment, apparently because Bishop Waleran had objected. Philip said they could apply again, but they must live apart meanwhile. Philip agreed that it was unjust, but he said it must be God’s will. It seemed more like ill will to Aliena.

The bitterness of regret was a weight she carried around with her, like the pregnancy. Sometimes she was more aware of it, sometimes she almost forgot about it, but it was always there. Often it hurt, but it was a familiar pain. She regretted hurting Jack, she regretted what she had done to herself, she even regretted the sufferings of the contemptible Alfred, who now lived in Shiring and never showed his face in Kingsbridge. She had married Alfred for one reason only, to support Richard in his attempt to win the earldom. She had failed to achieve her purpose and her true love for Jack had been blighted. She was twenty-six years old, her life was ruined, and it was her own fault.

She thought nostalgically of those early days with Jack. When she first met him he had been just a little boy, albeit an unusual one. After he grew up she had continued to think of him as a boy. That was why he had got under her guard. She had turned away every suitor, but she had not thought of Jack as a suitor, and so she had let him get to know her. She wondered why she had been so resistant to love. She adored Jack and there was no pleasure in life like the joy of lying with him; yet once upon a time she had deliberately closed her eyes to such happiness.

When she looked back, her life before Jack seemed empty. She had been frantically busy, building up her wool business, but now those busy days appeared joyless, like an empty palace, or a table laden with silver plates and gold cups but no food.

She heard footsteps and sat up quickly. It was Jack. He was thin and graceful, like a scrawny cat. He sat beside her and kissed her mouth softly. He smelled of perspiration and stone dust. “It’s so hot,” he said. “Let’s bathe in the stream.”

The temptation was irresistible.

Jack pulled off his clothes. She watched, staring at him hungrily. She had not seen his naked body for months. He had a lot of red hair on his legs but none on his chest. He looked at her, waiting for her to strip. She felt shy: he had never seen her body when she was pregnant. She unlaced the neck of her linen dress slowly, then pulled it off over her head. She watched his expression anxiously, afraid he would hate her swollen body, but he showed no revulsion: on the contrary, the look that came over his face was one of fondness. I should have known better, she thought; I should have known he would love me just as much.

With a swift movement he knelt on the ground in front of her and kissed the taut skin of her distended belly. She gave an embarrassed laugh. He touched her navel. “Your belly button sticks out,” he said.

“I knew you were going to say that!”

“It used to be like a dimple-now it’s like a nipple.”

She felt shy. “Let’s bathe,” she said. She would feel less self-conscious in the water.

The pool by the waterfall was about three feet deep. Aliena slid into the water. It was deliciously cool on her hot skin, and she shivered with delight. Jack got in beside her. There was no room to swim-the pool was only a few feet across. He put his head under the waterfall and washed the stone dust out of his hair. Aliena felt good in the water: it relieved the weight of her pregnancy. She ducked her head under the surface to wash her hair.

When she came up for air, Jack kissed her.

She spluttered and laughed, breathless, rubbing the water out of her eyes. He kissed her again. She put out her arms to hold herself steady, and her hand closed on the hard rod standing upright between Jack’s loins like a flagpole. She gasped with pleasure.

“I’ve missed this,” Jack said in her ear, and his voice was hoarse with lust and some other emotion, sadness perhaps.

Aliena’s throat was dry with desire. She said: “Are we going to break our promise?”

“Now, and forevermore.”

“What do you mean?”

“We’re not going to live apart. We’re leaving Kingsbridge.”

“But what will you do?”

“Go to a different town and build another cathedral.”

“But you won’t be master. It won’t be your design.”

“One day I may get another chance. I’m young.”

It was possible, but the odds were against it, Aliena knew; and Jack knew it too. The sacrifice he was making for her moved her to tears. Nobody had ever loved her like this; nobody else ever would. But she was not willing to let him give up everything. “I won’t do it,” she said.
