Alys nodded. 'It will thicken,' she said with certainty. 'I am going to get through this day without danger. I am going to escape the malice of these dolls. I am coming out of this with a whole skin.'

Morach shot her a look, half rueful, half amused. 'You have the power,' she conceded. 'Call up the fog then, and safety at any price.'

Alys nodded, half in jest. 'A thick fog,' she repeated. 'And my safety at any price, and…' She paused. 'Hugo in my arms before the day ends!'

Morach chuckled and shook her head. 'Impatient whore,' she said smiling. 'You want everything, and always at once!'

The fog lifted for a moment and the ponies trotted out more quickly along the road. Their unshod hooves made little sound on the soft mud. On either side of the track great bushes of gorse flowered, bright yellow, empty of perfume in the cold air.

A flock of lapwings lifted from a meadow by the track and wheeled across the sky, calling into the wind. All around them the fog lay grey and thick but above the two women was an eye of brilliant blue sky and a bright sun. 'Feel the warmth of that sun!' Morach said in delight. 'I love the sun after a cold winter. I've been chilled to my bones these last few days. Chilled and shaking. It's good to be out in the sunshine again.' Alys nodded, pushing the hood of her cape back. Her hair, free of a hood or cap, tangled into golden-brown curls. The colour was back in her cheeks. 'The castle is like a prison,' she said resentfully. 'Whether Catherine is sweet or sour it is wearying to wait on her.'

Morach nodded. 'As soon as the babe is born, I'm away,' she said. 'Back to my cottage.'

Alys nodded. 'You'll just be in time for winter then,' she observed. The child's due in October.'

Morach grinned. In a bush ahead of them a blackbird thrust out his chest and warbled a long rippling call. Morach whistled back, exactly the same notes, and the blackbird, half angry, half puzzled, repeated his song even louder.

'I know,' she said carelessly. 'But I'd rather die of cold on the moor than spend another winter in that castle.'

'Would you?' Alys asked. 'Would you really?' Morach looked around at her and the smile died from her face. 'No,' she said. 'I cannot abide the cold at the moment. I'd do anything rather than be cold and in the dark.'

Alys shrugged her shoulders. 'You've a whole summer ahead of you,' she said carelessly. 'Don't fret.'

Morach shrugged off the shadow which had touched her, lifted her face to the sunlight and half closed her eyes. 'And you?' she asked. 'Will you wait for Hugo? When this task of ours is done? Will you fatten up and learn to smile, wait for him to weary of his tired wife and puking babe? I thought you had grown impatient with waiting, I thought you were turning to magic again?'

Alys looked straight ahead at the swirl of mist before them which hid their road. 'You saw me with Hugo in the runes, and I dreamed of him and me together, and a son we would have. I want him, Morach, and both you and I have seen it. It must be there, waiting to happen. Tell me how I can get him.'

Morach pursed her lips and shook her head. 'You have your power,' she said. 'And you're young, and when you're not lovesick you are as beautiful as any girl in the country. Why wait and pine for Hugo? There are other men.'

Alys looked out along the straight lane ahead of them, stretching along the shoulder of the hill. 'I want him,' she said steadfastly. 'The moment I saw him I knew desire. I was straight out of the nunnery, Morach, and he was the first man I had ever seen in my life who was a match for me. I wanted him then as a bird seeks a mate. Nothing could stop me. Nothing could stop him.'

Morach gave a cracked laugh, hawked and spat. ' You stopped him!' she exclaimed. 'Stopped him in his tracks. Turned him cruel and twisted, a monster to his own wife. Set them dancing a wicked little dance. And now he loves her.'

Alys' eyes narrowed, her whole face looked pinched and mean. 'I know,' she said through her teeth. 'I should have taken the risk of him loving me and not meddled with magic. I should have trusted him to care for me. But I was anxious for my own safety…' she broke off. 'I wouldn't take the risk,' she said.

Morach grinned. 'Still the same story then,' she said cheerfully. 'You run to save your own skin and then find you have lost the one thing you needed.'

Alys' pony checked and side-stepped at her sudden grasp on the reins. 'Yes,' she said sharply, as if Morach's wit had struck as hard as a stone. 'Yes. My God, yes.'

There was silence for a moment. 'Best give him up,' Morach said. 'That's the other lesson your life is teaching you. When something is gone – it's gone. Even if you lost it by your own folly or cowardice. You've lost your Mother Abbess and you've lost Hugo. Give them both up. Let them go. The past belongs to the past. Find another love, Alys, and hold on to it this time. Take a risk for it.'

Alys shook her head. 'I have to have Hugo,' she said. 'There are too many promises between us. I had a Seeing. I can give him a son and I still think that Catherine will not. I have to be the lady at that castle, Morach. It is what I want and it is where I belong. I have dreamed of it over and over. Even if the love is gone, even if I have twisted and changed him – even twisted and changed myself. I want the castle. I want to be first with Hugo and the old lord. I want the dream that I dreamed, even if I am no longer fit for it.' Morach shrugged, watching Alys enmesh herself. 'How can I get it?' Alys pressed her. 'Good God, Morach, lovelorn wenches are your speciality. How can I get him, him and the castle? There are spells, surely?'

Morach laughed shortly. 'There are none to make a man love you,' she said. 'You know that as well as I. There are no tricks to make love come and stay. All magic can do, all herbs can do, is to summon lust.'

'Lust is no good,' Alys said impatiently. 'He's lusty enough. And with everyone else. I want him to want only me. Only me.'

Morach smiled. 'Then you have to give him some pleasure that no other can give,' she said. 'You have to take him out of his mind with desire. You have to let him ride the goddess.' 'What?' Alys demanded.

Ahead of them the mist was like a grey, wet wall. 'So much for sunshine,' Morach said, and hunched her shawl around her shoulders so they trotted into the darkness and it enveloped them.

The ponies' feet were even quieter on the soft wet mud. Around them the leaves of the hedgerows dripped wetly. The dark green of the hawthorn was flecked with white buds. Then the hedgerows gave way to open moorland and they could hear the distant sighing sound of the river.

'What d'you mean, ride the goddess?' Alys asked, her voice muffled and low.

'Poison,' Morach said matter-of-factly. 'There's a toadstool, the little grey one – earthroot, it's called.'

'I know that,' Alys interrupted. 'You give it dried and pounded in food to cure feverish dreams and lustful visions.'

Morach nodded. 'Take it fresh, or baked so it is sweet, and it will cause a fever, aye, and dreams like madness,' she said. 'If you want a man so badly that you do not care what it costs, you trick him to eat the earthroot, and then you whisper wild dreams and visions. You dance for him naked, you lay him on his back, you lick him all over like a bitch with a puppy. You do whatever enters your head to give him pleasure, any way.'

Alys was breathing fast. 'And what does he do?' she asked.

Morach laughed shortly. 'He sees visions, he dreams dreams,' she said. 'He may think you are the goddess herself, he may think he is flying high in the skies and having his lust on the stars. Any dream you whisper to him he will take for his own – delight or nightmare, the choice is yours.'

'And after?' Alys asked. 'When he has taken his pleasure and awakens?'

Morach chuckled her slow malicious chuckle. 'Then you use your power as a woman,' she said. 'No witchcraft is needed then. You swear that all he dreamed was true – that you are a witch and you have led him into the wild places that only we know. If he is fool enough – and you are barefaced enough – he will never go with another woman. Other women are the earth to him after that, plain and ordinary. You are fire and water. and air.'

Alys' face was alight. 'I'll have him,' she said. 'I'll trap him with that. It's what he wanted from me from the first.' She paused for a moment. 'But the cost,' she said, suddenly cautious. 'What's the price for all this, Morach?'

Morach laughed wildly. 'You should have been a usurer, not a witch, Alys. A usurer. You never touch a thing but you have to know the price. You never take a risk. You never gamble all! Always careful, always counting. Always self-preserving.' 'The cost,' Alys insisted.

'Death,' the woman replied easily. 'Death for the man.'

At Alys' sharp look she nodded. 'Not at once, but after a while,' she said. 'A few doses may make little difference but if you drug him again every week, say, for six months, then his body cannot live without it. He needs it like other men need food and water. He needs it more than he needs food and water. He is your slave then, your dog. You do not have to bed with him unless you please, he needs the world of dreams with or without you. He is a dog begging for its bowl of food. And he lives as long as a dog will live – five, six years.'

'Have you used it?' Alys asked curiously.

Morach's smile was hard. 'I have used everything,' she said coldly.

Alys nodded, and they rode on in silence for a little while, the noise of the river growing louder as they came nearer.

'Is the river in flood?' Alys asked, her voice muffled by the cloth she had wound around her face.

'Not yet,' Morach said. 'But it's rising. If it rains in the hills then it will spout out of the caves and flood the valley. It's been a wet winter this year.'
