‘Hang on, Gem. There’s an accident.’

Beside her a ghostly teenager – boy? girl? – with a shock of dark hair, stood with his hands in his pockets, his shoulders slumped and, turning briefly away from a policeman who was writing something, another child – no, a small woman, her hair tied back into a scrappy ponytail. She was lifting her hands in exasperation in a gesture that reminded him of Lara. You are so annoying!

He had driven a further hundred yards before he understood the jolt that went through him. He knew that woman. He racked his brain: bar? Holiday park? He had a sudden image of her taking his car keys, a memory of her removing his glasses in his house. What was she doing out there with children at this time of night? He pulled over and glanced into the rear-view mirror, watching. He could just make out the group. The little girl had sat down on the dark verge, the dog a mountainous black lump beside her.

‘Ed? Are you okay?’ Gemma’s voice broke into the silence.

Afterwards he wasn’t entirely sure what made him do it. Perhaps it was an attempt to delay his arrival back in that empty house to sit staring at a television screen until the small hours. Perhaps it was the strangeness of it – that making himself part of such a scene seemed no longer an odd thing to do in a life that had gone so far off the rails.

Perhaps it was just that he wanted to convince himself, against all available evidence, that he was not entirely an arsehole.

‘Gem, I’ll have to call you back. It’s someone I know.’

He pulled over and did a three-point turn, driving back down the dimly lit road slowly until he reached the police car. He pulled up on the other side of the road.

‘Hi,’ Ed said, lowering the window. ‘Can I help?’

They let Nicky out at a quarter to five. Tanzie handed over the Nintendo she’d brought on the bus from home and watched silently as he played with grazed fingers. Her happy mood had disappeared a bit when she first saw Nicky’s swollen face. It didn’t really look like him and she’d had to make her eyes stay very firmly on his when they would have liked to go somewhere else, even to the stupid picture of galloping horses on the wall opposite, which didn’t even look like horses. She wanted to tell him about how they’d registered at St Anne’s, but it was hard to think about it too much in that little room, with the smell of hospitals in her nose and Nicky’s eye all the wrong shape.

He made funny little sounds as he walked, and tried to close his mouth over them, like he didn’t want to let on how much it hurt. Tanzie found herself thinking, The Fishers did this, the Fishers did this, and she felt a bit scared because she couldn’t believe anyone they knew would do this for no reason. Mum had to have all the usual arguments with the hospital people about how, no, she wasn’t his actual mum, but as good as. And, no, he didn’t have a social worker. And it always made Tanzie feel a bit odd, like Nicky wasn’t a proper part of their family, even though he was.

When Nicky got up to go down the corridor she put her hand gently into his, and even though normally he would have told her to ‘Scoot, small fry’ or one of the other stupid things he said, he just squeezed her fingers a bit and his swollen mouth gave her this little smile, like just for once she was allowed (or at least until he said, ‘Tanze, mate, I do actually need to go to the loo now’).

Mum’s face was all pale, and she kept chewing her lip, like she wanted to say a lot more than she did. Nicky didn’t look at her once.

And then, when lots of doctors and people arrived in his room, Mum told Tanzie to wait outside and she walked up and down the long antiseptic corridors, reading her papers and working on her algebra. Numbers always made her feel better. If you treated them properly they always did what they were meant to do – like there was a magical order all around that you could unlock if you had the right key.

Nicky was dressed when she went back in. He walked out of the room really slowly, and he remembered to thank the nurse.

‘Nice lad, isn’t he?’ she said. ‘Polite.’

Mum was gathering up his things. ‘That’s the worst bit,’ she said. ‘He just wants to be left alone.’

‘Doesn’t really work like that round here, though, does it?’ The nurse smiled at Tanzie. ‘Take care of your brother, eh?’

As she walked towards the main entrance behind him, Tanzie wondered what it said about their family when every single conversation they had now seemed to end with a funny look and the words ‘Take care.’

Mum made dinner and gave Nicky three different-coloured pills to take, and they sat watching television on the sofa together. It was Total Wipeout, which normally made Nicky pretty much wee himself laughing, but he had barely spoken since they returned home, and she didn’t think it was because his jaw hurt. He looked weird. Tanzie thought about the way those boys had jumped on him and the woman who had dragged her into the shop so that she wouldn’t see and she tried to block out the thought because the sound of them hitting him still made her stomach go a bit funny, even though Mum said she would never, ever let it happen again, and she was not to think about it, okay?

Mum was busy upstairs. Tanzie could hear her dragging drawers out and going backwards and forwards across the landing. She was so busy she didn’t even notice it was way past bedtime.

She nudged Nicky very gently with her finger. ‘Does it hurt?’

‘Does what hurt?’

‘Your face.’

‘What do you mean?’ He looked at her like he didn’t know what she was talking about.

‘Well … it’s a funny shape.’

‘So’s yours. Does that hurt?’

‘Ha-ha.’

‘I’m fine, Titch. Drop it.’ And then, when she stared at him, ‘Really. Just … forget it. I’m fine.’

Mum came in and put the lead on Norman. He was lying on the sofa and didn’t want to get up and it took her about four goes to drag him out of the door. Tanzie was going to ask her if she was taking him for a walk but then the really funny bit was on where the wheel knocks the contestants off their little pedestals into the water and she forgot. Then Mum came back in.

‘Okay, kids. Get your jackets.’

‘Jackets? Why?’

‘Because we’re leaving. For Scotland.’

She made it sound perfectly normal.

Nicky didn’t even look round from the television. ‘We’re leaving for Scotland.’ He pointed the remote control at the screen, just to check.

‘Yup. We’re going to drive.’

‘But we haven’t got a car.’

‘We’re taking the Rolls.’

Nicky glanced at Tanzie, then back at Mum. ‘But you haven’t got insurance.’

‘I’ve been driving since I was twelve years old. And I’ve never had an accident. Look, we’ll stick to the B roads, and do most of it overnight. As long as nobody pulls us over we’ll be fine.’

They both stared at her.

‘But you said –’

‘I know what I said. But sometimes the ends justify the means.’

‘What does that mean?’

Mum threw her hands up in the air. ‘There’s a maths competition that could change our lives and it’s in Scotland. Right now, we haven’t got the money for the fares. That’s the truth of it. I know it’s not ideal to drive, and I’m not saying it’s right, but unless you two have a better idea then let’s just get into the car and get on with it.’

‘Um, don’t we need to pack?’

‘It’s all in the car.’

Tanzie knew Nicky was thinking what she was thinking – that Mum had finally gone mad. But she had read somewhere that mad people were like sleepwalkers – it was best not to disturb them. So she nodded really slowly, like this was all making perfect sense, and she fetched her jacket and they walked through the back door and into the garage, where Norman was sitting in the back seat and giving them the look that said, ‘Yeah. Me too.’ She climbed in. It smelt a bit musty, and she didn’t really want to put her hands down on the seats because she had read somewhere that mice wee all the time, like non-stop, and mouse wee could give you about eight hundred diseases. ‘Can I just run and get my gloves?’ she said. Mum looked at her like she was the crazy one, but she nodded, so Tanzie ran and put them on and thought she probably felt a bit better.
