‘It’s impossible,’ Hazel said that afternoon, in the Den, but she didn’t sound sure.
‘There are meant to be lots of other universes,’ Nathan said. ‘That isn’t just in books; Father Clement told us about it, in physics. There are millions of them, some like ours, some different. It’s called the multiverse. Supposing, in my dream, I was actually in one of them, and somehow I pulled that man out, back into ours?’
‘That’s ridiculous,’ Hazel said, curiously daunted. When they were much younger, the two of them had spent a lot of time exploring wardrobes in the hope of making their way into other worlds; but she had outgrown such fancies now. Or so she told herself, part wistful, part scornful, strangely afraid. She knew Nathan would never lie to her.
‘You’re talking about magic,’ she said at last. She had no opinion of physics.
‘Maybe.’ Nathan was pensive. ‘What is magic, anyway? According to someone or other, it’s just science we don’t understand.’
‘How do we find out more?’
‘I don’t know. I could ask Uncle Barty: he knows about lots of things. History, and archaeology, and all the sciences. Besides, Mum says his cooking is definitely magical.’
Hazel made a snorting noise. ‘Cooking isn’t magic,’ she said. ‘Even if that chocolate cake for your last birthday was amazing … Are there books on it? Magic, not cookery.’
Nathan nodded. ‘They’re called grimoires. Mum had some in once. I thought they would be interesting, but they were awfully dull, just about drawing runes and symbols, and picking herbs at the full moon, and boring rituals for calling up demons. There weren’t even any sacrifices, let alone stuff about other worlds. They wouldn’t be any good to us.’ There was a long silence, filled with frustrated thought. ‘What we need,’ said Nathan, ‘is a witch. Witches were burnt here, hundreds of years ago, in that open space outside the church. Uncle Barty told me about it. I asked him if they were real witches, and he said mostly not – but “mostly” isn’t all. I read the names: some of them were Carlows, like your great-grandmother. Was she born a Carlow, or did she marry one?’
‘Both, I think,’ Hazel said, frowning. ‘Dad’s always telling Mum her family are inbred. He said Great-grandma was barmy, and she married her own cousin, which is supposed to make your children mad or sub or something … He says she’s a witch, too, but I expect that’s just an insult.’
‘We could go and ask her,’ Nathan suggested tentatively. ‘She wouldn’t mind us asking – would she? It isn’t as if witches get burnt nowadays.’
‘She’ll mind,’ Hazel said with conviction. ‘She’s … well, you know.’
Nathan did know. Effie Carlow’s acid tongue and eagle stare did not encourage idle questions. However …
‘If we can’t think of anyone else,’ he said, ‘we’ll have to ask her. We must ask someone.’
Back at school, he tried to listen to the news on the Common Room radio as much as possible, but there was nothing further about the man on the beach. He sounded out Father Clement on alternative universes, but the monk said that to his knowledge nobody had ever visited one, though he assumed it would be feasible. In theory. By Friday night when his mother took him home to Eade, Nathan had made up his mind. On Saturday George came round, so it was not until Sunday that he told Hazel: ‘We have to go and see your great-grandmother. There isn’t anyone else.’
Effie Carlow lived in a cottage on the Chizzledown road about half a mile outside Eade. Built in the Victorian era, weathering had mellowed its façade and climbing plants had overgrown its more commonplace features, rendering it attractive if not picturesque. Too small to be of interest to buyers from London, it had diminutive windows admitting little light into poky rooms and a roof that sagged almost to ground level, while at the rear there was an outhouse which Effie rented to a local artist as a studio. The walled garden was a miniature wilderness in which weeds and wild flowers predominated. ‘We ought to telephone her first,’ Nathan had said before they set out.
‘She isn’t on the phone,’ said Hazel.
It was about four o’clock when they arrived, a well-chosen hour for a casual visit, or so Nathan hoped. After a nervous exchange of glances with Hazel, he tapped twice with the knocker, noticing belatedly that there was also a doorbell hiding behind a tendril of creeper. After a long wait during which they strained their ears for the sound of approaching feet and heard nothing, the door opened a few inches. ‘Well?’ said Effie Carlow.
‘Hello, Great-grandma,’ Hazel mumbled, and ‘We’re sorry if we’re interrupting,’ from Nathan, ‘but there’s something we particularly wanted to ask you.’
The old woman looked him up and down with her raptor’s eye. When he didn’t continue, she said impatiently: ‘So ask me.’
‘It’s about witches,’ he said, feeling increasingly awkward. ‘I read in a local history book there were witches burnt at the stake here, a long time ago, and some of them were called Carlow. We wanted to know about – about witchcraft, and other worlds, and things, and we wondered if you would be able to help.’
There was a change in her expression which they couldn’t define, a sort of sharpening, though her glance was always sharp, a subtle adjustment. Then she opened the door wider. ‘Come in.’
They stepped straight into a sitting room crowded with furniture and bric-a-brac. Pictures and bookshelves jostled on the walls, chairs were squashed arm to arm, small tables supported lamps, teacups, ornaments, an old-fashioned wireless. None of the lamps were on and in the gloom they could make out few details, but the overall effect was that of a jumble sale in a telephone booth. ‘Sit down,’ Effie continued. They sat in adjacent chairs, not quite holding hands, while she made them bitter dark tea with very little milk and added, as an afterthought, a plate of stale biscuits. ‘I’ve been keeping these for a special guest,’ she explained. ‘You can have some, if you like.’
‘Thank you,’ Nathan said politely, ‘but I had a big lunch.’
‘You can have some.’
Impelled by her determination, he took a biscuit. Hazel followed suit. She was still surprised they had been invited in and had lapsed into an apprehensive silence, leaving Nathan to do the talking. He attempted to phrase a question but was foiled by the biscuit, which was tough and required extensive chewing.
‘Why do you want to know about witches?’ Effie demanded. ‘Witches … and other worlds and things. But the Carlow witches were of this world, until they were burned. What goes on in other worlds no man knows.’
‘Nathan does,’ Hazel whispered. Her biscuit had proved more disposable.
‘And what does Nathan know?’
‘I have – these dreams,’ he said, between swallows. ‘There’s this place – I see different locations, a city, and a shoreline, but I know it’s the same place – and there are flying vehicles, like cars without wheels, and people riding on birds which are really reptiles, sort of pterodactyls – and I tried to rescue this man who was drowning, and a few days later I heard something on the news about an illegal immigrant, and I – I knew it was the same man.’
‘How could you tell?’ Effie’s manner was brisk.
‘They described his clothes. He was in a kind of one-piece suit which covered him all over, with a hood for his face and head. And they said he spoke no English, and they couldn’t work out his nationality.’
‘Inconclusive,’ Effie said. ‘An illegal immigrant might well wear a one-piece, a wetsuit or similar, if he had swum ashore. I heard that news item: they said so. As for your dreams – witches know about dreams, I won’t deny that, but it sounds to me like you’ve been watching too many science
