Sam adjusted his collar. His face had become dangerously still.

And just as I realized I was holding my breath, the policeman was there, between them. Donna’s hand was on Sam’s sleeve and she was steering him back to the young lad on the kerb. The policeman muttered something into his radio, his hand on the drunk’s shoulder. The boy swung round and spat on Sam’s jacket. ‘Fuck you.’

There was a brief, shocked silence. Sam stiffened.

‘Sam! Come on, give me a hand, yes? I need you.’ Donna propelled him forwards. When I caught sight of Sam’s face, his eyes glittered as cold and hard as diamonds.

‘Come on,’ said Donna, as they loaded the semi-comatose lad into the back of the truck. ‘Let’s get out of here.’

He drove silently, Lily and I wedged into the front seat beside him. Donna cleaned the back of his jacket as he stared ahead, stubbly jaw jutting.

‘Could be worse,’ Donna said cheerfully. ‘I had one throw up in my hair last month. And the little monster did it on purpose. Shoved his fingers down the back of his throat and ran up behind me, just because I wouldn’t take him home, like I was some kind of bloody minicab.’

She stood up and motioned for the energy drink she kept in the front. ‘It’s a waste of resources. When you think what we could be doing, instead of scooping up a load of little …’ She took a swig, then looked down at the barely conscious young boy. ‘I don’t know. You have to wonder what goes on in their heads.’

‘Not much,’ said Sam.

‘Yeah. Well, we have to keep this one on a tight leash.’ Donna patted Sam’s shoulder. ‘He got a caution last year.’

Sam glanced sideways at me, suddenly sheepish. ‘We went to pick up a girl from the top of Commercial Street. Face smashed to a pulp. Domestic. As I went to lift her onto the gurney, her boyfriend came flying out of the pub and went for her again. Couldn’t help myself.’

‘You took a swing at him?’

‘More than one,’ Donna scoffed.

‘Yeah. Well. It wasn’t a good time.’

Donna shifted to grimace at me. ‘Well, this one can’t afford to get in trouble again. Or he’s out of the service.’

‘Thanks,’ I said, as he let us out. ‘For the lift, I mean.’

‘Couldn’t leave you in that open-air asylum,’ he said.

His eyes briefly met mine. Then Donna shut the door and they were gone, heading for the hospital with their battered human cargo.

‘You totally fancy him,’ said Lily, as we watched the ambulance disappear.

I had forgotten she was even there. I sighed as I reached into my pockets for the keys. ‘He’s a shagger.’

‘So? I would totally shag that,’ Lily said, as I opened the door to let her in. ‘I mean, if I was old. And a bit desperate. Like you.’

‘I don’t think I’m ready for a relationship, Lily.’

She was walking behind me, so there was no way I could actually prove it, but I swear I could feel her pulling faces at me the whole way up the stairs.

CHAPTER TWELVE

I wrote to Mrs Traynor. I didn’t tell her about Lily, just that I hoped she was well, that I was back from my travels and would be in her area in a few weeks with a friend, and would like to say hello if possible. I sent it first class, and felt oddly excited as it plopped into the post-box.

Dad had told me over the phone that she had left Granta House within weeks of Will’s death. He said the estate workers had been shocked, but I thought back to the time I had spotted Mr Traynor out with Della, the woman he was now about to have a baby with, and I wondered how many genuinely had been. There were few secrets in a small town.

‘She took it all terrible hard,’ Dad said. ‘And once she was gone your redheaded woman there was in like Flynn. She saw her chance, all right. Nice auld fella, own hair, big house, he’s not going to be single for long, eh? Speaking of which, Lou. You – you wouldn’t have a word with your mother about her armpits, would you? She’s going to be after plaiting it if she lets it all grow any longer.’

I kept thinking about Mrs Traynor, trying to imagine how she would react to the news about Lily. I remembered the joy and disbelief on Mr Traynor’s face at their first meeting. Would Lily help to heal her pain a little? Sometimes I watched Lily laughing at something on television, or simply gazing steadily out of the window lost in thought, and I saw Will so clearly in her features – the precise angles of her nose, those almost Slavic cheekbones – that I forgot to breathe. (At this point she would usually grumble, ‘Stop staring at me like a weirdo, Clark. You’re freaking me out.’)

Lily had come to stay for two weeks. Tanya Houghton-Miller had called to say they were off on a family holiday to Tuscany and Lily didn’t want to go with them. ‘Frankly, the way she’s behaving right now, as far as I’m concerned, that’s fine. She’s exhausting me.’

I pointed out that, given Lily was barely at home, and Tanya had changed the locks to her front door, it would be pretty hard for Lily to exhaust anyone unless she was tapping at their window and singing a lament. There was a short silence.

‘When you have your own children, Louisa, you might eventually have some idea what I’m talking about.’ Oh, the trump card of all parents. How could I possibly understand?

She offered me money to cover Lily’s board and lodging while they were away. I took some pleasure in telling her I wouldn’t dream of taking it, even though, frankly, it was costing me more than I had anticipated to have her there. Lily, it turned out, wasn’t satisfied with my beans-on-toast or cheese-sandwich suppers. She would ask for cash, then return with artisan bread, exotic fruit, Greek yoghurt, organic chicken – the staples of a wealthy middle-class kitchen. I remembered Tanya’s house, the way Lily had stood by the oversized fridge and thoughtlessly dropped chunks of fresh pineapple into her mouth.

‘By the way,’ I said, ‘who is Martin?’

There was a short pause. ‘Martin is my former partner. Lily apparently insists on seeing him, even though she knows I don’t like it.’

‘Could I have his number? I’d just like to make sure I know where she is. You know, while you’re gone.’

‘Martin’s number? Why would I have Martin’s number?’ she squawked, and the phone went dead.
