‘OK.’ Lucy wipes her hands down her thighs – rubbing away sweat or the feel of that photo, I can’t tell. ‘OK. OK. I guess the beginning was maybe seven or eight months after Ash’s mum died – so about two and a half years ago? Ash and I were out for a pint, and she said, “Guess what I’m going to do.” She was ducking her head down and looking up at me like this, out of the corner of her eye, this bashful little smile – for a second I thought she was going to get a nipple piercing or something . . .’ Lucy laughs, a small dry sound. ‘If only. But then she said, “I’m going to find out what happened to my dad.” Which was the last thing I expected. She was always making up stories about where he was, or the ways he might come back; but she’d never talked about actually tracking him down.’

I say – I can sound as empathetic as anyone – ‘Maybe she didn’t feel able to do it while her mam was alive. Looking after her would’ve taken all of Aislinn’s energy; I’m not surprised she had none left for her da.’

Lucy’s nodding fast. ‘That’s what I figured. I thought it could be a good idea – not finding him, specifically; there were too many ways that could go pear-shaped. But this was the first time she’d ever come up with a plan to go after something she wanted. I thought that had to be good, for her to learn how to do that. Right? That makes sense, right?’

‘Total sense,’ I say – and I actually mean it – and watch the relief rush through Lucy. ‘She wasn’t going to get a lot out of life till she did.’

‘Exactly. So I said great idea, fair play to you. Aislinn told work she had a dentist appointment, dressed up in her best gear, and went in to the Missing Persons squad. They gave her the runaround at first, but finally this detective looked up her dad on some computer system and said he was dead. Aislinn was . . .’ Lucy bites down on her lips, remembering. ‘God. She was devastated. She rang work and said the anaesthetic had made her feel faint and she couldn’t come in, and then she went home and cried all day. I went over there after work, and she looked like roadkill. Everything had gone out of her; she was just . . . lost.’
