embarrassed that Ellen should have made that assumption so readily. "Are you worried?"
Ellen shrugged. "A mother is always worried."
"Has he quarreled with Alfred?" Aliena said nervously.
"I asked the same question. Alfred says not." Ellen sighed. "I don't suppose he's come to any harm. He's done this before and I daresay he'll do it again. I never taught him to keep regular hours."
Later in the evening, just before bedtime, Aliena called at Tom's house to see whether Jack had reappeared. He had not. She went to bed worried. Richard was away in Winchester, so she was alone. She kept thinking Jack might have fallen into the river and drowned, or something. How terrible that would be for Ellen: Jack was her only son. Tears came to Aliena's eyes when she imagined Ellen's grief at losing Jack. This is stupid, she thought: I'm crying over someone else's sorrow about something that hasn't happened. She pulled herself together and tried to think of another subject. The surplus cloth was her big problem. Normally she could worry about business half the night, but tonight her mind kept returning to Jack. Suppose he had broken his leg, and was lying in the forest, unable to move?
Eventually she drifted into a restless sleep. She woke at first light, still feeling tired. She threw on her heavy cloak over her nightshirt, and pulled on her fur-lined boots, then went outside to look for him.
He was not in the garden behind the alehouse, where men commonly fell asleep, and were saved from freezing by the heat of the fetid dunghill. She went down to the bridge and walked fearfully along the bank to a bend in the river where debris was washed up. A family of ducks was scavenging among the bits of wood, wornout shoes, rusty discarded knives and rotting meat bones on the beach. Jack was not there, thank God.
She went back up the hill and into the priory close, where the cathedral builders were beginning their day's work. She found Tom in his shed. "Has Jack come back?" she said hopefully.
Tom shook his head. "Not yet."
As she was going out, the master carpenter came up, looking worried. "All our hammers have gone," he said to Tom.
"That's funny," Tom said. "I've been looking for a hammer and can't find one."
Then Alfred put his head around the door and said: "Where are all the masons' bolsters?"
Tom scratched his head. "It seems as if every hammer on the site has disappeared," he said in a baffled voice. Then his expression changed, and he said: "That boy Jack is behind this, I'll bet."
Of course, Aliena thought. Hammers. Felting. The mill.
Without saying what she was thinking, she left Tom's shed and hurried across the priory close, going past the kitchen, to the southwest corner, where a channel diverted from the river drove two mills, one old and the other brand-new. As she had suspected, the wheel of the old mill was turning. She went inside.
What she saw confused and frightened her at first. There was a row of hammers fixed to a horizontal pole. Apparently of their own volition the hammers lifted their heads, like horses looking up from the manger. Then they went down again, all together, and struck simultaneously with a mighty bang that made her heart stop. She gave a cry of shock. The hammers lifted their heads, as if they had heard her cry, then they struck again. They were pounding a length of her loose-woven cloth that lay in an inch or two of water in a shallow wooden trough of the type used by mortar makers on the building site. The hammers were felting the cloth, she realized, and she stopped being frightened, although they still looked disturbingly alive. But how was it done? She saw that the pole on which the hammers were fixed ran parallel with the shaft of the mill wheel. A plank fixed to the shaft went round and round as the shaft turned. When the plank came around, it connected with the handles of the hammers, pushing the handles down so that the heads came up. As the plank continued to turn the handles were released. Then the hammers fell and pounded the cloth in the trough. It was exactly what Jack had talked about that evening: a mill that could felt cloth.
She heard his voice. "The hammers should be weighted so that they fall harder." She turned around and saw him, looking tired but triumphant. "I think I've
