'Yes, that would be Karen,' Dan said.

'Never mind, they needn't catch any of you. Listen: the task force aimed at Camp Cerridwen is two platoons in four helicopters, taking off at Z minus one, which means, they'll be here about 0630. They have orders to kill everybody except Moira and Dan, but not to fire the camp – it'd start a forest fire and even Harley knows that every hectare of Forestry Commission plantation is going to be precious. The radio equipment is to be wrecked. So all you have to do is to move out on the twentieth – every man, woman and child of you – and hide in the forest, somewhere kilometres away, there's plenty of it. If you can do that, without leaving clues or even hinting at it in the village, you can save yourselves and the camp… If you ever have a chance to come back to it, that is,' he added sombrely.

"We'll worry about that afterwards,' Moira told him. 'We can hide ourselves and take Geraint's radio stuff with us. But there's something else you'd better know about. Eighteen of us, including Dan and me, will almost certainly be busy somewhere else on D-Day…' and she told about the Psychic Assault Group and the stone circle.

‘Do you find that… shall we say, a little bizarre?' Dan asked when she had finished.

'Setting fire to a hut by psychic effort? Three or four months ago I'd have thought you were either lying or suffering from group hallucination. But since then… Not only have Brenda and I personally experienced what the Black Mamba can do – which might be put down to hypnotism, just – but there's something else you don't know. You heard about the recent earth tremor, down south?'

'Yes. Two of Geraint's ham pals reported it.' There was a sudden gleam of extra interest in all the witches' faces and Gareth wondered why.

'The epicentre was Salisbury Plain. And just at that time, the Angels of Lucifer conducted a human sacrifice at Stonehenge. If that was coincidence…'

'It wasn't,' Moira and Dan said together, and Moira went on: 'We picked up the ritual – in fact, it woke several of us up. And our best clairvoyant insisted it was a human sacrifice. She saw the big megaliths, too. That's what gave us the idea of experimenting with a stone circle… Then when we heard about the tremors we thought it must have had something to do with it.'

They launched into a discussion of earth currents, ley lines and foci of power which left Brenda bewildered, though Gareth seemed to be taking an unsurprised interest in it. She was not disbelieving because the evidence was plain enough but she was soon out of her depth in the technicalities. But when they started talking about positive action against the Angels of Lucifer, she ventured to intervene.

'Did the Angels intend the earth tremors, do you think?'

'We don't know,' Dan told her, 'but we think it's unlikely. They were probably testing their own strength, seeing what power they could raise by human sacrifice at the Henge and not worrying too much about what the power actually did once they'd raised it. And they are powerful, even without ritual human sacrifice or a stone circle as an amplifier. So I'm not surprised at what did happen.'

'If I know Karen,' Jean Thomas said, 'she'll have been delighted at what happened.'

'But if you try to do the same thing – without the sacrifice, of course – couldn't it be dangerous?' Brenda asked. 'Couldn't you trigger off an earthquake or something equally disastrous?'

Moira shook her head. 'We'll be defending Mother Earth, not outraging her like the Angels of Lucifer. She looks after her own.'

'Do you really see her that way? As a conscious entity, able to decide who's on her side and who isn't?'

'Experience points that way,' Moira smiled. 'But yes -the short answer is, we do. We see the whole universe as conscious, at various levels of complexity and on various time-scales – various wavelengths, if you like. Witchcraft is largely a method of learning how to tune in to the right frequencies. All religion is, really… The Earth-Mother is one aspect of the Goddess, of what we conceive as the female polarity of the Ultimate – the side that gives birth and nourishes and re-absorbs and re-shapes, while the other side – the male polarity, the God – impregnates and energizes. We see all creation and activity as the outcome of polarity, even at Divine level… Again, all religions do, however they obscure it… The Earth-Mother is how the Goddess expresses herself on and in our planet, our particular corner of the universe. For the past two or three thousand years, mankind has over-emphasized the God-aspect and tried to push the Goddess into the background or deny her altogether. In the end, that's as much an offence against the God as against the Goddess; deny him his complement, and you deny him… Do you know what Camp Cerridwen is? Not just a survival community trying to feed and house and organize ourselves. We're trying to get ourselves back on the Earth-Mother's frequency, to talk to her and listen to her. Not only the witches, either – all of us, in our own way. Father Byrne, for instance; if ever a man talked to her face-to-face, he does, whatever he calls her… Am I answering your question – about our running into danger, I mean?'

Brenda hesitated. ‘Yes, I think you are – though it's a bit much to take in all at once. Can we discuss it some more, when you've time?'

'Of course we can. But right now the point is – we've got to fight the Angels of Lucifer on the Earth-Mother's behalf, if you see what I mean. And when we do, it's by putting ourselves on her frequency and calling on her power, so it can't be destructive except to her enemies. Does that sound naive?'

Brenda laughed, suddenly. 'I like you people. You make the most extraordinary statements without batting an eyelid and then ask solicitously if we think you're being "bizarre" or "naive". Tell you the truth, I don't know. But you're on the right side and you're doing something. So just tell me how I can help and we'll philosophize about it afterwards, win or lose.'

'Fair enough,' Dan grinned at her. 'Now, Gareth – down to business. Do you know how the Angels of Lucifer fit into Operation Skylight? From what you say, Harley and Karen must have planned something for them to do.'

'I'm only piecing hints together,' Gareth said, 'but I'm damn certain they've planned something. I was still courier between them and escort for her when she commuted with Beehive, up to a fortnight ago, and I kept my eyes and ears open. Karen has some kind of operation arranged for D-Day. And it's silly the way you pick things up – but their kitchen at her headquarters has a big calendar on the wall, where the cook notes things. I got a look at it last time I took her back and the cook had scribbled "Breakfast 3 am" opposite 21 June. That's two hours before sunrise and three before zero hour. My guess is that at sunrise, they'll be at Stonehenge, raising all the power they can to back up Operation Skylight. What else was their last experiment at the Henge for? It must have been a rehearsal for the time when Harley will need their support. And that means D-Day.'

'It makes sense,' Dan agreed. 'And that means our PAG must be in action at the same time.'

Jean Thomas turned to Gareth and asked: 'When you were at Karen's place did you hear anything about Avebury?' Everybody smiled; Jean and Fred Thomas's devotion to Avebury, the megalithic site nearly thirty kilometres north of Stonehenge, was known to everyone in the camp. Avebury was less spectacular and world-famous than Stonehenge, and its stones were smaller, but it covered a far greater area with Avebury village at its centre; many witches and occultists, and even archaeologists, found it more interesting and rewarding than its famous neighbour.

'Not much,' Gareth answered. 'I know it's outside the territory they control. I heard a bit of conversation about it once – someone suggested taking it over but Karen said no, it wasn't worth it, Stonehenge was enough. I sort of gathered there were only a handful of villagers living there.'
