'Shut up,' said the voice of the drawler but now the voice was sharp and angry. 'If we have to pull this cottage down, if we have to lift every slab there is, if we have to take over that camp, I'll do it! I tell you, this makes all the difference between wealth and poverty! Anyone who wants to back out can do so - but he'd better be careful!'

'Now boss, now boss, don't you fly off the handle!' said the woman. 'We're all in this! We'll do all you say. Look, let's start by lifting a few more slabs. There are not so very many that are the size that Paul figured on this plan.'

Then began a boring time for the two hidden boys, as slab after slab was lifted and put back. Nothing was found under any of them, apparently.

The men went to the out-buildings too, leaving the woman in the cottage. The boys thought she had gone as well, and Julian moved a little, feeling rather cramped after being still for so long. The woman's ears must have been sharp for she called out at once.

'Who's there? Is it you, Tom?'

The boys stiffened and stood like statues. The woman said no more. It was not long before the men came back, talking among themselves. It sounded as if there were three of them.

'No go,' said the drawler. 'I think we'll have to search that camp really well again.'

'That's going to be difficult with someone already there,' said the woman.

'We'll deal with him,' said a voice, grimly. Julian frowned. Did that mean that Guy was in danger? He had better warn him!

'I'm fed up with this place,' said the woman. 'Let's go. I don't think the slab is anywhere here! We're wasting our time!'

To the boys' great relief, the four searchers left the cottage and went off together. Julian and d.i.c.k leaned over the crumbling wall of the room they stood in, and watched the lights of the torches and lanterns getting dimmer and dimmer over the common. Good! Now they could go back to the girls!

'I'm stiff!' said d.i.c.k, stretching himself.

'Well, Ju - we know a lot more now, don't we? It's clear that someone called Paul has stolen some valuable blue-prints of something - maybe a new plane, or battles.h.i.+p perhaps - and has hidden them in some secret place he knew of about here - and to get to it you have to lift a slab of stone of a certain size.'

'Yes. And we know the size because we've already seen the one they lifted in the old stables,' said Julian. 'I vote we go there and measure it - or measure the one by the sink. I should think that the right slab will be somewhere in the old camp. We'd better tell Guy and let him into the secret. He'll help us to search!'

'What a peculiar business this is to find ourselves mixed up in,' said d.i.c.k. 'All because George didn't like people laughing at old Timmy with a cardboard collar round his neck! Timmy's the cause of this!'

The boys went down the stone stairs, and, of course, d.i.c.k quite forgot about the rambler, which caught him neatly round the ankle and almost tripped him headlong down the stairs!

'Blow!' he said, clutching Julian and nearly making him topple too. 'Sorry. It was that rambler again. It's ripped my ankle all round. Put on the torch for goodness' sake.'

They carefully measured the stone slab by the sink and then made their way out of the cottage and up towards the spring, hoping that they would find the great gorse-bush in the dark. They tried to get under the wrong one at first, but at last found the right one. They heard a small welcome bark from Timmy.

'Oh! Julian! d.i.c.k! Is it you?' said Anne's voice, as the boys squeezed through into the hollow middle. 'Oh, what AGES you've been! We haven't slept a wink. Keep still, Timmy, do - this place is too small for you to rampage about in!'

The boys settled down and torches were put on. Julian related the curious happenings to the two interested girls. George was thrilled.

'Oh I say! Fancy all this springing up out of the blue so suddenly! What are you going to do?'

'Warn Guy first thing in the morning - and then get in touch with the police, I think,' said Julian. 'We ourselves can't stop the men searching the camp, and as soon as they do find the slab they're looking for, they can easily get what they want and go off with it!'

'Well, it's really thrilling,' said George. 'I wish I'd been with you. I'll never go to sleep tonight!'

But they did manage to drop off to sleep, for they were all very tired. After a few hours, just as dawn was breaking, Timmy lifted his head and growled. George awoke at once.

'What is it, Tim? I can't hear anything.'

But Timmy could, that was certain. George woke Julian, and made him listen to Timmy's continuous growling.

'What do you think he's growling at?' she asked. 'He keeps on and on. I can't hear a thing, can you?'

'No,' said Julian, listening. 'Well, it's no use my creeping out and going searching in the dark for whatever Timmy's growling at. It might be something silly like a weasel or a hedgehog or a stoat. Shut up, Tim. That's enough.'

Although it was as dark as night under the thick old gorse-bush, outside it was just getting light. What was Timmy growling at? Were there people about again? Or was it just one of the hedgehogs he so heartily disliked?

He stopped growling at last and put his head down on his paws, closing his eyes. George patted him.

'Well, whatever it was, it's gone. Are you comfy, Julian? It's very cramped in here - and hot too, isn't it?'

'Yes. We'll get up fairly early and go to warn Guy - then we'll have a swim,' said Julian, yawning. He switched off his torch and went to sleep again.

It was late when they awoke. d.i.c.k was the first, and he looked at his watch. He gave an exclamation.

'Gos.h.!.+ It's half past eight! Hey, Ju - Anne - George - wake up, it's almost afternoon!'

Everyone felt stiff and cramped, and they went off to have a swim and to warn Guy. As they came near the camp, they stopped in amazement.

Someone was howling down in the trench, howling so miserably and so broken-heartedly that the Five felt quite panic-stricken. Whatever in the world could have happened? They ran to the edge of the excavations and looked down into the trench.

The boy was there, lying on his face, sobbing. He kept lifting his head and howling, then putting it down again.

'Guy! GUY! Whatever's happened?' shouted Julian. He leapt down beside the boy. 'Are you hurt'? Is Jet hurt? What's the matter?'

'It's Guy! He's gone! They've taken him,' howled the boy. 'And I was so awful to him. Now he's gone. He'll never come back, I know he won't!'

'Guy's gone? But - but you're Guy!' said Julian in astonishment. 'What do you mean?'

He felt sure that the boy really was mad now - quite mad - talking about himself like that. He patted him on the shoulder. 'Look - you're ill. You come along with us. You need a doctor.'

The boy sprang to his feet, his face swollen and stained. 'I'm not ill! I tell you Guy's gone. I'm not Guy. He's my twin. There are two of us.'

Everyone gasped. It took half a minute to think about this and get everything straight - and then, of course many things were clear! There was not one mad boy, there were two ordinary boys - but they were twins! There wasn't, as they had thought, just one boy who contradicted himself all the time, who seemed continually to appear suddenly and unexpectedly, and who was sometimes nice and sometimes not.

'Twins! Why on earth didn't we think of that before?' said Julian. 'We thought there was only one of you. You were never together.'

'No. We quarrelled - quarrelled bitterly,' said the boy, tears in his eyes again. 'And when twins quarrel, really quarrel, it's worse than any quarrel there is! We hated one another then - we really did! We wouldn't be with one another, we wouldn't eat together, or dig together, or sleep together. We've often quarrelled before, but not like this - not like this! I just pretended that he didn't exist - and he did the same with me!'

'What a to-do!' said Julian, astonished and worried. 'Well now - what's happened to make you so upset? Tell me!'

'Guy wanted to be friends with me again last night,' said the boy. 'And I wouldn't. I hit him and walked away. Then this morning I was sorry and went to find him and be friends - and - and...'

He stopped and howled again. Everyone felt very sad and uncomfortable. 'Go on, tell us,' said Julian, gently.

'I was just in time to see him fighting two men, and screaming at them, and kicking - then they hustled him away somewhere!' said the boy. 'I fell down in the trench and hurt my leg - and by the time I dragged myself up, Guy had gone - and so had everyone else!'

He turned away and wept again. 'I'll never forgive myself, never! If I'd made friends last night I could have helped him - and I didn't!'

Chapter Fifteen

WELL DONE, GEORGE!

It was Anne who comforted the boy. She went to him and pulled him down on a stone beside her. 'Let me look at your leg,' she said. 'It's pretty bad, isn't it? Look, I'll bind it up for you. Don't be so upset - we'll help you. I think we know what's happened, don't we Julian?'

The boy looked at Anne gratefully, and sniffed hard. When she offered him her handkerchief, he took it and wiped his face. d.i.c.k gave Anne his big hanky to bind up the boy's cut and bruised leg. He must have fallen right into the trench in his fright at seeing his brother fighting and being taken away.

'How do you know what's happened?' he said to Julian. 'Can you get Guy back? Do say you can! I'll never forgive myself for this. My twin-brother - and I wasn't there to fight by his side when he needed me!'

'Now don't soak my hanky all over again!' said Anne. He gave her a forlorn little smile and turned to Julian again.

'My name's Harry Lawdler, and Guy and I are mad on old camps and buildings and things. We spend almost all our holidays together, digging and finding all kinds of things, like these.' He nodded his head towards the little shelf of relics that the four had seen before.

'Yes - Guy told us,' said d.i.c.k. 'But he never said a word about you. We were often very puzzled - we thought you and he were one boy - not two, you see - and we couldn't understand a lot of things you both said. You're so very, very alike.'

'Well - I tell you, we each pretended that the other didn't even exist,' said Harry. 'We're like that. We love each other best in the world, and we hate each other worse - when we quarrel. We're simply horrible then!'

'Can you tell us a bit about the people that Guy was fighting?' asked d.i.c.k.

'Yes. They were some that came before, wanting Guy to clear out while they had a look round,' said Harry, wiping his face again. 'Guy was pretty rude to them. In fact I heard him say that if they messed about his camp he would throw stones at them - he's like that, you know, very fierce, when he's roused.'

'And you think these were the same people?' said d.i.c.k. 'Which way did they go with Guy?'

'That way,' said Harry, pointing. 'I've hunted the whole camp round, but they're gone - disappeared into thin air! It's extraordinary!'

'Let's have a hunt round,' said Julian. 'We might find something. But I imagine that the searchers have taken Guy off with them because he knew too much - perhaps they found here what they were looking for, and saw Guy watching.'

'Oh! Then we're too late!' said George, in deep disappointment. 'They've got what they want - and they'll disappear now and never be caught. I expect by now they are speeding away in a fast car - and have taken Guy with them to make sure he doesn't talk before they're safely in another country!'

'Oh no!' cried Harry. 'He's not kidnapped, is he? Don't say that!'

'Come on - let's have a hunt,' said Julian, and they all made their way among the various trenches and pits, looking for they hardly knew what.

They gave it up after a while. There were too many slabs and stones of all sizes! Besides, what good would it be even if they found the right one? The birds had flown - presumably with what they had come for! In fact, if Guy hadn't come along and seen the searchers, n.o.body would even have known that they had been in the camp and made a successful search!

'It's no good,' said Julian, at last. 'This is too big a place to know where to look for anything that might help us. Let's go back to the gorse-bush and collect our things, return to Kirrin and go to the police. It's the only sensible thing left to do!'

'Come along, Harry,' said Anne, to the miserable twin. He was so full of remorse that her handkerchief was now soaked for the third time! 'You'd better come with us and tell all you know.'

'I'll come,' said Harry. 'I'll do anything to get Guy back. I'll never quarrel with him again. Never. To think that...'

'Now don't go all through that again,' said Anne. 'Look, you're upsetting Timmy so much that his tail is down all the time!'

Harry gave another forlorn little smile. They all left the camp and made their way back to the gorse-bush. It was only when they got there, and began pulling out the tins of food, as well as the rug and other things, that they realized how extremely hungry they were!

'We've had no breakfast. We've been up for ages, and it's very late. I'm simply starving!' said George.

'Well, if we finish up all the food, we shan't have to carry the tins!' said d.i.c.k. 'Let's have a meal. Ten minutes more here can't make much difference.'

They were thankful not to have to sit under the gorse-bush again. They sat outside in the sun, and discussed everything.

'I believe when Timmy began to growl and growl about six o'clock this morning, it was because he could hear those people coming quietly by to go to search the camp,' said George.

'I think you're right,' said Julian. 'I bet they searched the camp well - till Guy woke and came on the scene and fought like fury. It's a pity I didn't squeeze out from under the bush and follow them, when Timmy growled.'

'Anyone want a drink?' said George. 'I'll go and fetch some water from the spring. Where's the pineapple tin?'

Anne pa.s.sed it to her. George got up and took the little rabbit-path that led to the spring. She could hear it gurgling and bubbling as she came near - a very pleasant noise.

'Water always sounds nice,' said George to herself. 'I love the sound of water.'

Water! Now why did that ring a bell in her mind just then? Who had been talking about water? Oh - d.i.c.k and Julian, of course, when they had come back from the old cottage last night. They had told Anne and herself about the word on the plan - the word that might have been WATER, not WADER.

'I wonder which it was,' said George to herself as she idly held the pineapple tin to the gurgling water. She gazed at the beautiful little spring, jutting up from the stony slabs - and then another bell rang loudly in her mind.

'Stone slabs! Water! Why - I wonder - I just wonder - if one of these slabs is the one! This one just here is about the right size!'

She stared at it. It was set firmly in a high little bank at the back of the place where the spring gurgled up and then ran into the clean stony channel. Did it hide anything behind it?

George suddenly dropped the tin and ran back to the others at full speed. 'Julian! Julian! I believe I've found the slab! It's been staring us in the face the whole time!'

Julian was very startled. So were the others. They stared up at George in astonishment.

'What do you mean, George?' said Julian, jumping to his feet. 'Show me!'

Followed by everyone, George ran back to the spring. She pointed to the white slab behind the water. 'There!' she said. 'That's the right size, isn't it? And it's beside WATER - just as it said in the plan you told us about - only the people thought it was WADER.'

'Gosh - I wonder if you're right, George,' said Julian, excited. 'You might be - you never know. Sometimes springs come from underground pa.s.sages - secret, hidden ways into the earth.'

'Let's try and move it,' said d.i.c.k, his face red with sudden excitement. 'It looks pretty hefty to me.'

They began to struggle with the stone, getting extremely wet as they splashed about in the spring. But n.o.body minded that. This was too exciting for words. Harry helped too, heaving and tugging. He was very strong indeed.

The stone slab moved a little. It slid to one side and stuck. More tugging. More pulling. More panting and puffing!

'I believe we'll have to get help,' said Julian at last. 'It really is too heavy and well-embedded.'
