'No!' Caitlin said, horrified. 'Don't ever say that! All my life's in the past now. You've got a chance to save Rosetta, that's the important thing.'
'There isn't a thing I can say that won't sound like daytime TV advice, but don't talk about your life being in the past-'
'Well, it is.' They reached the jumble of stones that Crowther had called the Whispering Knights. Iron railings protected them from prying fingers, but Caitlin desperately wanted to touch their cool surface. When I started out on the road to this place, I was in a terrible state… didn't really know what I was doing. When I finally came to my senses and the professor told me what he planned… well, if I was a sane, rational woman with everything to live for, I would have walked away there and then. I can still barely believe that this mythical Otherworld really exists, but the professor is convinced. If it doesn't, we've got nothing to lose. But if it does, we're going to a place filled with dreams and nightmares… a place where humans aren't supposed to exist. How long do you think we might possibly last there?'
'But we've got to try, haven't we?'
Caitlin reached across the railings and just managed to touch one of the stones; her fingers tingled in response. 'Yes, you've got to try for your daughter, and if there's a chance of finding a cure for the plague, as Professor Crowther seems to think there is, then I've got to try, because, you know, better me…'
'I wish you wouldn't be so fatalistic. It might be catching.' He stared across the sweep of the field to the trees hiding the Rollrights. 'I'm keen to meet this professor. He seems to know a lot of stuff. What is he, like Doctor Who or something?'
Caitlin laughed at the idea. 'Just wait till you meet him.'
'You trust him?' 'He seems OK. I don't think he tells the whole truth. He doesn't lie, exactly, it's just that he doesn't give you the whole picture.' Caitlin realised that Matt was staring intently back towards the standing stones. 'What is it?'
'I don't know. Probably nothing. I thought I saw something…' He gave her a tight smile. 'Look, you wait here. I'll check it out and then come back for you.'
Before Caitlin could protest, he was loping away through the grass. She waited for an uncomfortable moment, but there was an eerie atmosphere now that she was standing all alone in the wide open space and she decided to set off after Matt.
She'd only gone a few paces when there was a crack of thunder, though the sky was clear blue. A smell of burned iron rose up around her and she had the sense of a sudden, crackling light at her back. She spun round to see the Whispering Knights shimmering as if she were looking at them through a heat haze.
And then a figure emerged from behind them and rapidly began to move towards her. Her first, shocked impression was that it was some black-skinned monster with the head of a pig. Her second notion gave her a true picture: it was a knight in gleaming black armour, a sword hanging from his belt, but his helmet was in the shape of a boar's head.
'Get away!' Briony screamed from Caitlin's mouth as the knight marched implacably towards her. She turned and she ran, trying not to stumble over the uneven ground, and she knew that this was what she had seen from her window on the evening Grant and Liam had contracted the plague. It had followed her from there to here, and even in the Ice-Field that thought filled her with a powerful dread.
'What is it?' Matt had run back and caught her shoulders; she fell into his arms.
'He's coming!' Briony screamed. Matt peered over her shoulder, then slowly turned her round. The field behind was empty, save for the Whispering Knights keeping their lonely vigil. Back at the campfire, Matt managed to comprehend Caitlin's mental state with the aid of Mahalia's less than sympathetic descriptions. As she calmed, Briony receded and Caitlin returned. She was happy to see that Matt still treated her in the same friendly manner.
'I did see somebody,' Caitlin said.
Mahalia twirled a finger at the side of her head before winking at Carlton. But the boy didn't join in; his dark eyes suggested only the deepest sympathy. Caitlin smiled at him and nodded her thanks.
'Who the hell is this!' They all jumped as Crowther marched up, roaring as he jabbed a furious finger at Matt. 'Good Lord, don't you stupid people understand what we're about! Why don't you summon up every thug and bandit in the area-'
'I'm not a bandit,' Matt said, standing up and extending a hand. 'I prefer the term desperado. I've always had a cowboy thing going on.'
'Ahhhhh!' Crowther roared, throwing his arms into the air as if he were going to attack Matt. 'Get out, damn you!'
Caitlin jumped up to throw herself between Matt and Crowther. 'Professor, just a minute, I asked him to stay-'
'Is that supposed to calm me down? Someone with a tenuous grip on her own mental health finds a kindred spirit? I should beat you all to death with my staff now and be done with it!'
It took Caitlin a good twenty minutes to convince Crowther. He raged about waifs and strays and hangers- on compromising their security, and in the end Caitlin had to call on the services of a shrieking, neurotic Briony. Only then did Crowther back down, unable to cope with her psychosis.
Realising he was powerless to change anything, Crowther retired to the other side of the stones to brood, while Mahalia climbed on to the roof of the hut to throw stones at the wildlife. Carlton sat with Caitlin and Matt, listening to their conversation and smiling easily. Matt was surprised to hear Caitlin's stories of the intensity of the plague — he'd heard a couple of rumours in the local village but had seen nothing. That gave Caitlin some hope that its spread wasn't as fast as she'd feared. It was Mahalia who spotted the professor sneaking off, from her vantage point on top of the hut. She dropped down and encouraged the others to follow him, but somehow he gave them all the slip. Half an hour later, his anguished cry rang across the valley. Their blood chilled, fearing the worst, Matt led Caitlin into the field, but they found the professor staggering towards them, looking haggard. Blood trickled down either side of his face.
'What happened?' Caitlin said. She reached out to examine his wounds, but Crowther knocked her hand away. Yet the action shifted his hair and she saw, or thought she saw, a hole drilled into the side of his head. 'Who did that to you?' she asked, concerned.
'Nobody did it to me,' he snapped. 'I've been finding out the information we need — someone has to.' He barged past them, but despite his demeanour they both saw his hands were shaking uncontrollably.
Back at the camp, he sat next to the fire to warm himself, though it wasn't particularly cold. 'I know how to cross over,' he said in a thin voice. 'I had an idea before, but now I know it all.' He jabbed a finger towards Caitlin. 'You're the key.'
'Me? But why me?'
'I presumed you were,' Crowther continued as if she hadn't spoken. 'And I know where we have to go for the cure once we get to wherever it is we're going. Somewhere called the House of Pain.'
Matt laughed, eliciting a glare from Crowther. 'It couldn't be called the House of Fun, could it? You're making this up.'
'I'm going to ignore you,' Crowther said, 'and just talk to her.' He indicated Caitlin. 'I was told-'
'Who told you?' Caitlin interrupted.
'That doesn't matter.' His voice was wearier now. 'But the road will be long… and hard.' The shadows stretched out as the day drew to a close and soon Crowther was ready to begin his preparations. He took them to the centre of the circle where they could watch the sky for the exact moment of sunset. None of them were prepared to back out, despite Crowther's ominous information; even Mahalia was insistent.
'So you really know what you're doing?' Matt asked in a tone that suggested he didn't think the professor knew at all. Crowther ignored him, but Matt persisted. 'People always said these stone circles had something mysterious about them,' he continued. 'Everybody thought it was just superstition.'
This time Crowther couldn't resist. 'There you have it. The clues have been before us for centuries, but in our arrogant belief that earlier people were ignorant, uneducated, superstitious barbarians, we ignored the truth that was hidden away in the old stories. Things that seem inherently stupid on the surface are metaphor and symbol. The stones coming to life, moving around, that means…'
'I'm not so sure that's a metaphor,' Caitlin whispered.
Everyone followed her gaze to the stones, which now appeared to have a thin blue light limning their edges in
