Which leaves Tilly.
And twelve tiny, but slowly growing, vicious deckchairs.
And one parasol.
Oh and a hole in the rock.
The rock is comparatively simple. Grandma comes with us to have a look.
‘Ooh my,’ she says. ‘It must go all the way to the castle. So you think it’s the meteorite dust mixed with the water?’ she asks Eric.
He nods. ‘Yes, and it’s a steady flow, there must be water trickling through somewhere. If we drain it into the sea then it would dissolve harmlessly.’
Jacob stares at the crack. ‘Couldn’t I just melt the rock until it seals up?’
We all stare at him.
‘That’s almost a genius suggestion,’ says Eric. ‘Except the water needs to come out somewhere.’
‘We could drill another hole,’ says Jacob, ‘somewhere else in the rock, just not in the cave.’
‘O – K,’ I say. ‘How? Where?’
Jacob doesn’t answer, just swaggers down the beach and stops under the pier where the sea comes in closer to the shore.
He turns to Eric. ‘Ready, tap-fingered Snot Face?’
‘S’pect so.’ Eric looks bewildered.
Jacob fires a fireball at the rock, smashing it and heating it up until it smokes.
Eric sprays it. For a second the rock steams and then, shocked by the extreme temperatures, crumbles.
Again, Jacob fires sheets of flame.
Again, Eric shoots water.
This time, a tiny crack becomes a fissure, and quickly the fissure becomes a canyon, and before very long water begins to dribble from the hole, seeping into the sand and down to the sea.
‘Wow, Jacob,’ says Eric. ‘Thermal shock – excellent.’
‘Wow indeed,’ says Grandma.
So that’s one problem solved.
Then there are the remaining deckchairs.
‘You can’t leave them running about, Tom, you do know that, don’t you?’ says Grandma. ‘You boys will have to round them up.’
We find them roosting in the bird reserve. A line of little chairs and a single parasol snapping and chattering alongside the limpets.
‘Now what?’ says Jacob.
‘We can try to steam-clean them again,’ I say.
‘Or just burn them,’ says Jacob, sparks leaping from his fingers.
But perhaps they hear us, or perhaps they’re really turning into seabirds, because the moment we approach all twelve dive from their perch into the sea and swim off, leaving the parasol, which twirls once, puts itself up and floats onto the water before drifting seawards, squeaking and rustling in search of its friends.
‘What will happen to them?’ I ask, scratching my head.
‘Ultimately they’ll become waterlogged,’ says Eric.
‘Or set up a colony somewhere,’ says Eric.
I gaze at the beach furniture until I can’t be sure if they’re what I’m seeing or simply part of the horizon.
‘Suppose they wash up in France and attack people there?’ I say.
‘Not our problem,’ says Jacob.
‘So you haven’t really learned anything about empathy then?’ says Eric.
‘What?’ says Jacob.
‘Don’t worry,’ says Eric. ‘I don’t think I can be bothered to explain.’
‘Of course I’m pleased that Dad’s stopped coming to school!’ shouts Tilly, dropping baby otter into a pan of boiling water.
‘Why are you doing that?’ asks Eric, reaching for a spoon and leaning over the pan.
‘He’s been bad,’ she says, brushing Eric away. ‘And I want him to beg for mercy.’
‘But he’s plastic,’ I reply. The fake fur curls away from baby otter’s nose revealing the brown plastic underneath.
‘Exactly,’ she replies. ‘He’s altogether unresponsive.’ She barely pauses for breath. ‘But I’m furious that Dad’s going to be on the beach all day – imagine – every single person at school will see him forever and ever selling those deckchairs and pedalos and –’ she pauses for a long dramatic sigh – ‘it’ll be terrible – no one will ever talk to me again – I’ll be sent to Coventry, ostracised, given the cold shoulder – never again invited to anyone’s birthday party, never again taken home after school, never again voted for in the best handwriting competition, never again sing the solo, never again picked to be teacher’s helper – it’ll be –’ she drags in a breath – ‘terrible.’
Jacob, who has so far stayed silent, gazes at Tilly, his mouth wide. ‘Awesome,’ he says. ‘That was utterly awesome.’
‘It was rather good, wasn’t it?’ says Tilly, smiling, and poking at baby otter who is now almost completely bald.
We all stare at the brown plastic thing bobbing in the boiling water.
‘It won’t be that bad, Tilly,’ I say. ‘Over time they’ll forget that he’s our dad – and it’s so much better than having him on the bus. And he won’t be out and about in the winter. He’ll be painting deckchairs or whatever it is that Mr Fogg did in the winter. And Mum’s not going to be mayor. She’s just going to be Eric’s dad’s right-hand man, so people won’t really know she’s there either.’
Tilly stops prodding baby otter and takes the pan from the stove. She turns to look at me, folding her arms and relaxing her shoulders. She scrapes the point of her toe in a semi-circle, glances out of the window and then back at me. ‘I suppose you’re right. I’m overreacting, and I realise that it’s not just me suffering with all this – it’s you too, Tom.’ She smiles at me. A genuine, warm, loving, sisterly smile.
We stare at her, open-mouthed.
