Within a few seconds the others joined him. David shone his torch beam around the walls.
âIf we just take them from the top, maybe we can go over?' he suggested.
âGive it a go,' grunted Martin.
They all worked quickly, moving and stacking the rocks until there was a space big enough to crawl through. On the other side, the tunnel stretched on into blackness.
âYes!' said Martin, exchanging a high-five with David.
For what seemed like hours they explored, going up one dead-end tunnel after another, lowering themselves through holes in the floor, clambering up through holes in the ceiling, scrambling out backwards when there wasn't room to turn around. Martin showed them the right marks to make on the tunnel walls at every intersection, while he sketched a new section of the map.
Kitty had had enough after ten minutes, and occupied herself by looking behind rocks and in small fissures in the walls, and any other likely hiding places for treasure.
Then, miraculously, Martin found what he was looking for: a tunnel leading upwards with steps hewn into the rock.
âSee,' he said triumphantly, as his torch beam caressed the stone edges. âThere's a reason for this.'
However, at the top of the steps he was disappointed to find a short ladder with steel rungs, leading nowhere. There was no trapdoor, just earth, roots and a jumble of rocks. He looked down at the others in disgust.
âWell, this isn't right,' he said. âIt doesn't make sense at all.'
âThere must have been an exit once,' said David. âSomething's collapsed and the stones have filled the hole, then dirt and stuff must have kind of piled up on top.'
âWell, let's dig it out,' said Andrea. âI saw some tools in the bomb shelter. What's the quickest way back, Marty?'
âWait,' said David. âWe can't do it from below. If we start hacking at that soil the rocks'll just fall on our heads. We've got to figure out where the entrance is up top and dig down.'
âOkaaaaayyyy.' Martin sat down and studied his map. The others looked at him expectantly.
âWhat are you looking at me for?'
âWell,' said Andrea. âWhat sort of a mapmaker are you?'
âWell, come on. It'd be different if I had a GPS or something.'
âI've got a GPS on my phone!' David pulled it out. They all crowded around.
âI've got a good signal. We must be close to the surface. Come on, come on. Stop jiggling, Kitty. I can't see it properly. Ah, here it comes . . . Hmmm. It says we're in Ultimo.'
They sat down at the foot of the ladder, dejected. Kitty handed around some apples.
âThe next model's better, apparently,' said David. âMuch more accurate.'
âThat's good to know,' said Andrea drily.
âWe could use Andrea's and David's phones, though,' said Kitty. âSee, we could have one down here, and one up top. And one lot of us could make a loud noise, and the others could call on the phone when they hear it, and when it gets louder, and so on.'
âHey, that's not a bad idea!' Martin brightened immediately.
âYou'd have to call me,' Andrea said. They all chorused with her: âI've got no credit.'
She took David's phone. âYou wouldn't have my number,' she said, a little shyly. âI'll put it in your contacts.'
âIt'd have to be a pretty loud noise, though,' Martin went on. âWhat have we got to make a noise with?'
âMaybe we could shout?' offered Andrea.
âMaybe,' said David doubtfully, taking his phone back. âIt'd be good if we had a whistle or something. Marty, doesn't your dad do some umpiring? Wouldn't there be a whistle at your place?'
âWhat, you want me to go all the way home and look for a whistle? Why do I have toâ'
Andrea's phone suddenly shrilled.
âSorry,' said David. âI hit the call button.'
âWhoa, Andrea,' cried Martin, putting his hands over his ears. âCould you make it a bit louder?'
The others all started laughing as Andrea shut the phone off, and he looked at them in bewilderment. âWhat? What did I say?'
Once they had worked out the details of the plan, the boys made their way back, picking up a mattock and shovel from the bomb shelter on the way. Martin had a rough idea of the general direction, and they agreed that they were looking for a spot in the garden at the side, rather than the front of the house. There would have to be trees, to account for the roots they had seen, and possibly some kind of stone structure.
The girls were left in semi-darkness, with just Martin's torch. Andrea had suggested that they also get some spades, but David was adamantly against it.
âBad idea!' he had said. âRemember what we said before? You don't want to be anywhere near the ladder when we start shifting that dirt.'
When they made the first phone call to Andrea, Martin could hear Kitty in the background plaintively asking: âIs that it? Have they found it?'
âWe're close,' he told Andrea. âDavid thought he could hear something when your phone started ringing.'
âWhere are you?'
âNear a rose garden.'
âAny ruined buildings?'
âNo, nothing.'
âHey, what about the naked lady?' said Andrea. âThat was all broken around the bottom. Go and have a look.'
âWhat are you talking about?'
âDavid knows.'
David grinned and led Martin through the roses to a statue on a broken base. The white lady gazed modestly downwards. They searched around her feet, but there was nothing but dead grass and cracked earth. David called Andrea again.
âGood guess!' he said. âWe definitely heard your phone this time. Yeah. Yeah. No, we're sort of at the side. There's nothing here.'
He looked up at Martin.
âShe says we should try around the back. Makes sense.'
There was a narrow space between the statue and the trees. The base was badly damaged on one corner. They pulled a couple of large stones away and called Andrea again.
This time they heard the phone ringing loud and clear, and they exchanged a high-five, whooping with glee. Andrea picked up immediately.
âHey, we heard you yelling!' she said. âBetter start digging!'
The two boys worked hard and as carefully as they could, but as soon as a gap appeared there was a yelp from below.
âStand back!' called David.
âSorry,' came Andrea's voice. âI see what you mean.'
Eventually the hole was big enough and Martin lowered himself down.
âCome on!' he called to the girls waiting below.
Andrea and Kitty climbed up and emerged into the sunlight. The entrance was well hidden in a tangle of undergrowth, and they arranged the broken stones to look undisturbed, but so they could get in again without too much effort.
âBrilliant!' Martin kept saying. âBrilliant!'
Kitty gave him half a banana and he scoffed it down.
âThis is great,' he said, looking around. âWe can come and go from the lane. If there are security guys in the house they won't see us.'
âSo how will all this appear on your map?' asked Andrea.
âDunno. I'll have to think up a sort of puzzle for this entrance. You know, kind of “Speak friend and enter”. Have to give it some thought. What food have you got left, Kitty?'
To his dismay, Kitty's backpack was empty.
âWe have to go, anyway,' said Kitty. âWe can come back tomorrow.'
âOkay.' David picked up the mattock and shovel. âLet's leave the torches in the bomb shelter with the tools. My folks have got people coming to lunch tomorrow, and they're kind of expecting me to be there. So Marty, can you come round at about two-ish with a really complicated maths problem? As in, a whole assignment?'
âI reckon I could do that. Earlier if you like.'
âNo, I want a chance to grab something to eat before you tear me away.'
âDavid,' asked Kitty, âwill Moshe be making one of those cakes?'
âA kugelhopf ? You can bet your life on it.'
âAny chance you can smuggle some out?'
âI'll give it a go. We could be lucky.'
They separated, feeling they had done a good afternoon's work.
Kitty was quiet on the way home. Still, thought Martin, no use worrying about her. The only thing that would make her happy was finding her so-called treasure. As if that was ever going to happen.
MARTIN
rang the doorbell at two o'clock sharp the next day, but there was no sign of David, only a hubbub of conversation and laughter from the back of the house. He rang again, leaning on the bell for a long time. Finally a young woman in a flouncy off-the-shoulder dress threw open the door, a glass of wine in her hand.
âWell, helloooo,' she crooned. âEither Linda's latest PA really is twelve, or you've come to see David.'
She tottered back up the hall in her high heels, and Martin followed. The courtyard at the back of the house was crammed with people, all waving wine glasses and talking at once. Martin stood on tiptoe and waved to David, who was pressed up against the side fence. Looming over him was Roger Mason, the local historian and antique dealer, a portly man in shapeless corduroys, a grubby shirt and a big red bow tie. Mason was talking animatedly, waving his arms around at great peril to other guests. David had a plate in his hand, and was shovelling food into his mouth as fast as he could. He noticed Martin, but gave a minuscule shake of the head and turned his gaze back to Roger.
David's mother materialised.
âHello, Martin! How nice to see you! Grab yourself something to eat.'
âOh, that'd be good, thanks . . . But actually, I kind of need Dave. There's this maths assignment I have to hand in tomorrow.'
âWell, take some food with you. And maybe you can both come back afterwards.'
On the way out, nicely laden with containers of food, Martin said to David, âYou didn't seem all that keen to get away.'
âTell you outside.'
Kitty and Andrea, who had been hovering discreetly a few doors up the street, joined them. As they walked towards the park, munching barbecued chicken legs, David explained. âRoger Mason was telling me about the coal mine. Did you know there used to be a coal mine here?'
âWhat, right here?'
âYes. The entrance and the above-ground stuff were right next to Tarcoola until they closed the mine, then they built the factory there.'
âThey closed the mine!' said Kitty. âThat's exactly what she said. Miss Gordon's father used to work there. The Pit, she called it. But I didn't know it was in Balmain. I always thought coal mines were . . . I don't know, somewhere far away.'
âSo the shafts and all the tunnels . . . ' began Martin.
âYou got it,' said David.
âThat day we went exploring,' said Martin. âDavid's Leap. Do you remember? There were â I saw something like railway lines way down below us. That's what they have in mines.'
âAnd when my candle went whoosh and burnt my hair,' said Andrea, âthat was methane, wasn't it? There's methane in coal mines.'
âYou're right!' David looked at her in surprise.
âWell, what do you think I'm doing in Science?' she challenged. âI haven't exactly got an iPod in my ear.'
David made an âI surrender' sign. âMethane's one of the reasons they closed it,' he said. âPeople would get poisoned, or they'd light those lanterns they had and, you know â
kaboom
! Roger told me.'
âThey had canaries, didn't they?' said Martin. âThey kept canaries in those mines, and if the canaries died, you know, from the gas, because they're so little . . . '
âThat's where she hid it!' Kitty ran ahead and stopped in front of the others, blocking their way.
âYou have to take me seriously now, you have to. It all fits. Her father worked in the mine. She said he knew where everything was. She said all the canaries died. She said that. Andrea, you know her. She's not mad.'
Martin groaned quietly. The others looked at each other.
âShe said, “The wolf boy can't go there. It's safe.” Now IÂ know what she meant.'
Still nobody spoke.
âWell, if you're not going to go into that mine, I am!'
âWait, Kitty!' David grabbed her arm. âI believe you. But you can't just go charging in there. We need a map of the mine, at least. He said there's information on the internet. Maybe there's a map?'
Kitty stamped her feet in frustration. âIt'll take too long!'
âSounds like there's only one way in,' said David. âRoger says if the development goes ahead they'll build over the last access to it, and the mine will be sealed forever. He says that means losing our history, and they shouldn't be allowed to do it.'
Now Kitty had tears in her eyes.
âListen, Kitty,' said David gently, âlet's just do a search. We'll find out as much as we can, then go in and have a proper look, see if your old lady's got something hidden down there. Okay?'
âOkay.'
âNow, we can't go back to my place, or we'll get sprung. So let's go to yours. We can eat this kugelhopf when we get there.'
âRight.' Kitty brightened.
The O'Briens' house was tidy and quiet, except for the low humming of the dishwasher and the rhythmic thwack, thwack of the printer. They went into the study, where there were open books and piles of printouts.
âOne of your parents has been busy,' remarked David, sitting down at the screen.
âIt's Mum,' said Martin. âShe's doing this course. Just leave all her stuff and switch to my login.'
On Martin's page, the New Mail icon was flashing. At the top of the list was a message titled âHa ha ha look what my brother snapped'.
Andrea leaned in for a closer look. âWho's Sam?'
Too late, Martin snatched at the mouse. Andrea had it in her hand and had clicked the message before he had fully taken in the situation.
The message itself was brief: âHey lover my brother took this picture with his new iPhone. Nice or what? Catch up soon. Sam.'
The picture, which was right there in the body of the message, in full colour with sharp detail, showed a foolishly smiling Martin being kissed by the lovely Samantha Buckingham.
Martin stood paralysed in the silent room as the others stared at the screen.
âThat's Samantha Buckingham,' said Andrea. âJeez, Martin!'
âShe's all right,' said Martin. âShe asked me out.'
âYou can't go out with that snooty, stuck-up bitch!'
âWhat! Who do you think you are, telling me what to do?' Stung, Martin spoke louder than he intended. His words hung in the air, then there was a flurry of movement and the front door slammed. Andrea was gone.
âAndrea's right, Martin,' said Kitty. âI think Sam Buckingham's father might be the wolf boy. See, the other day IÂ went to visit Miss Gordon, and . . . '
Martin turned on her.
âI've had enough of you and your fairy tales!' he shouted. âAll this buried treasure and the Big Bad Wolf. Grow up!'
âCome on, Marty,' started David.
âNo, that's enough. Enough!' Martin stormed out, ran up the stairs to his room and slammed the door.
He threw himself down on the bed. Who did David think he was anyway, always right about everything? And as for Andrea â there she was at school with those slutty girls, all sniggering at him, skipping Maths with the moronic boys from 7B who were always smoking down by the bike sheds.
He picked up the fantasy novel he had been reading, the fifth in the series, but he couldn't get into it. Resentment seeped through him like acid.
How could a good day turn bad so quickly? Nobody had asked if any of this was his fault. He couldn't really blame Samantha, though. She wasn't to know what an unreasonable lot of friends he had.
His thoughts strayed to the food they had picked up at David's house. Would Kitty think to keep a piece of kugelhopf for him? Probably not, he thought, feeling extra sorry for himself. She and David were probably polishing off the rest of it right now.
