‘I just moved in.’

‘One sofa, one television, two boxes of books?’ She nodded towards the chair on which I sat, my breathing still unbalanced, trying to make any kind of sense out of what she had just told me.

I stood up. ‘I’m going to get a drink. Would you like something?’

‘I’ll have a Coke. Unless you’ve got wine.’

‘How old are you?’

‘Why do you want to know?’

‘I don’t understand …’ I went behind the kitchen counter. ‘Will didn’t have children. I would have known.’ I frowned at her, suddenly suspicious. ‘Is this some kind of joke?’

‘A joke?’

‘Will and I talked … a lot. He would have told me.’

‘Yeah. Well, turns out he didn’t. And I need to talk about him to someone who is not going to totally freak out every time I even mention his name, like the rest of my family.’

She picked up the card from my mother and put it down again. ‘I’m hardly going to say it as a joke. I mean, yeah. My real dad, some sad bloke in a wheelchair. Like that’s funny.’

I handed her a glass of water. ‘But who … who is your family? I mean, who is your mother?’

‘Have you got any cigarettes?’ She had started pacing around the room, touching things, picking up the few belongings I had and putting them down. When I shook my head, she said, ‘My mother is called Tanya. Tanya Miller. She’s married to my stepdad, who is called Francis Stupid Fuckface Houghton.’

‘Nice name.’

She put down the water and pulled a packet of cigarettes from her bomber jacket and lit one. I was going to say she couldn’t smoke in my home, but I was too taken aback, so I simply walked over to the window and opened it.

I couldn’t take my eyes off her. I could maybe see little hints of Will. It was in her blue eyes, that vaguely caramel colouring. It was in the way she tilted her chin slightly before she spoke, her unblinking stare. Or was I seeing what I wanted to see? She gazed out of the window at the street below.

‘Lily, before we go on there’s something I need to –’

‘I know he’s dead,’ she said. She inhaled sharply and blew the smoke into the centre of the room. ‘I mean, that was how I found out. There was some documentary on television about assisted suicide and they mentioned his name and Mum totally freaked out for no reason and ran to the bathroom and Fuckface went after her so obviously I listened outside. And she was in total shock because she hadn’t even known that he’d ended up in a wheelchair. I heard the whole thing. I mean, it’s not like I didn’t know Fuckface wasn’t my real dad. It’s just that my mum only ever said my real dad was an asshole who didn’t want to know me.’

‘Will wasn’t an asshole.’

She shrugged. ‘He sounded like one. But, anyway, when I tried to ask her questions she just started totally flipping out and said that I knew everything about him that I needed to know and Fuckface Francis had been a better dad to me than Will Traynor ever would have been and I really should leave it alone.’

I sipped my water. I had never wanted a glass of wine more. ‘So what did you do?’

She took another drag of her cigarette. ‘I Googled him, of course. And I found you.’

I needed to be alone to digest what she had told me. It was too overwhelming. I didn’t know what to make of the spiky girl, who walked around my living room, making the air around her crackle.

‘So did he not say anything about me at all?’

I was staring at her shoes: ballerina pumps, heavily scuffed as if they had spent too much time shuffling around London streets. I felt as if I was being reeled in. ‘How old are you, Lily?’

‘Sixteen. Do I at least look like him? I saw a picture on Google images, but I was thinking maybe you had a photograph.’ She gazed around the living room. ‘Are all your photographs in boxes?’

She eyed the cardboard crates in the corner, and I wondered whether she would actually open them and start going through them. I was pretty sure the one she was about to go into contained Will’s jumper. And I felt a sudden panic. ‘Um. Lily. This is all … quite a lot to take in. And if you are who you say you are, then we – we do have a lot to discuss. But it’s nearly eleven o’clock, and I’m not sure this is the time to start. Where do you live?’

‘St John’s Wood.’

‘Well. Uh. Your parents are going to be wondering where you are. Why don’t I give you my number and we –’

‘I can’t go home.’ She faced the window, flicked the ash out with a practised finger. ‘Strictly speaking, I’m not even meant to be here. I’m meant to be at school. Weekly boarding. They’ll all be freaking out now because I’m not there.’ She pulled out her phone, as an afterthought, and grimaced at whatever she saw on its screen, then shoved it back in her pocket.

‘Well, I’m … not sure what I can do other than –’

‘I thought maybe I could stay here? Just tonight? And then you could tell me some more stuff about him?’

‘Stay here? No. No. I’m sorry, you can’t. I don’t know you.’

‘But you did know my dad. Did you say you think he didn’t actually know about me?’
