Behind Her Eyes: The Sunday Times #1 best selling psychological thriller. Sarah Pinborough

summer clothes to take with him. I’m sure Ian has it covered, but I want some input into this family holiday I’m not part of.

      I think about buying Lisa a gift of some baby clothes, but that really is too much too soon. Their new baby is nothing to do with me. Why would she want anything from the ex-wife anyway? The first child’s mother? The imperfect relationship. What has Ian told her about me? How much has he made my fault?

      Once Adam has disappeared inside, I keep my head down as I storm away, not wanting to get drawn into any summer holiday conversation with the other mothers, and I’m desperate for a cigarette and want to be around the corner before I light up. My clothes probably smell of smoke anyway, but I can live without the school-gate judgement.

      I feel the collision before I know I’ve had it. A sudden jolt to my head, the thump of a body against mine, a shocked yelp, and then I’m stumbling backwards. I stay on my feet although the other woman doesn’t. I see her shoes first, her feet tangled on the ground. Delicate cream kitten heels. No scuffs. I go into autopilot, and grab at her, trying to help her to her feet.

      ‘I’m so sorry, I wasn’t looking where I was going,’ I say.

      ‘No, it’s my fault,’ she murmurs, a voice like spun brown sugar in the air. ‘I wasn’t looking.’

      ‘Well, we’re both idiots then,’ I say, and smile. It’s only when she’s standing, willowy slim and tall, do I realise, in horror, who she is. It’s her.

      ‘It’s you,’ I say. The words are out before I can stop them. My morning has gone dramatically from bad to worse, and my face burns. She looks at me, confused.

      ‘I’m sorry, I don’t think we’ve met?’

      I take advantage of a small herd of prams coming past from the school to cover my embarrassment, and by the time they’ve passed, I manage what I hope is a genuine smile. ‘No, no we haven’t. But I work for your husband. Part-time, anyway. I’ve seen your picture on his desk.’

      ‘You work with David?’

      I nod. I like the way she says with and not for.

      ‘I just left him there. Fancied a morning walk,’ she says. ‘Small world, I guess.’

      She smiles then, and she really is oh-so-beautiful. The glimpse of her I’d had before didn’t do her justice – although I had been fleeing in panic to the toilet at the time – and I’d hoped that she just photographed well. But no. I feel like a solid clumsy lump of lard next to her, and I tuck one curl behind my ear as if that’s going to suddenly make me presentable.

      I’m wearing an old pair of jeans and a hoodie with a tea stain on the sleeve, and I haven’t even waved a mascara brush at my face before leaving the flat. She looks effortlessly chic with her loose bun and thin green sweater above a pair of pale green linen trousers. A vision in pastel that should look twee, but doesn’t. She belongs in the South of France somewhere on a yacht. She’s younger than I am, maybe not even quite thirty yet, but she looks like a grown-up. I look like a slob. She and David must make such a beautiful couple together.

      ‘I’m Adele,’ she says. Even her name is exotic.

      ‘Louise. Excuse the state of me. Mornings are always a rush, and when I’m not working I tend to prefer the extra half an hour in bed.’

      ‘Don’t be silly,’ she says. ‘You look fine.’ She hesitates for a second, and I’m about to pre-empt what I think is her looking for a way to say goodbye and get on with her day, when she adds, ‘Look, I don’t suppose you fancy going for a coffee? I’m sure I saw a cafe on that corner.’

      This is not a good idea. I know that. But she’s looking at me so hopefully, and my curiosity is overwhelming. This is the-man-from-the-bar’s wife. David is married to this beautiful creature and yet he still kissed me. My sensible brain tells me to make my excuses and leave, but of course that’s not what I do.

      ‘A coffee would be great. But not that place. It’ll be filled with the school mums within ten minutes, and I can live without that. Unless you’re keen on a babies’ crying chorus and lactated milk with your coffee.’

      ‘No, I don’t think so,’ she laughs. ‘You lead, I’ll follow.’

      We end up in the Costa Coffee courtyard with cappuccinos and slices of carrot cake that Adele insisted on buying. The morning chill is fading now that it’s nearly ten, and the sun is warm: I squint a bit as it shines low and bright over her shoulder. I light a cigarette and offer her one, but she doesn’t smoke. Of course she doesn’t. Why would she? She doesn’t seem to mind that I do, and we make polite conversation as I ask her how she’s settling in. She says that their new house is beautiful, but she’s thinking of redecorating some of the rooms to brighten them up and was going to go and pick out some paint samples this morning. She tells me their cat died, which wasn’t a great start, but now that David’s at work they’re settling into a routine. She says she’s still finding her way around. Getting used to a new area. Everything she says is charming, with a hint of disarming shyness. She’s lovely. I so wanted her to be horrible or bitchy, but she isn’t. I feel utterly dreadful about David, and I should want to be a hundred miles away from her, but she’s fascinating. The kind of person you can’t stop looking at. A bit like David.

      ‘Do you have friends in London?’ I ask. I think it’s a safe bet. Nearly everyone has some old friends lurking in the capital – leftovers from school or college who added you on Facebook. Even if it’s not your home town, it’s somewhere people always end up.

      ‘No.’ She shakes her head and shrugs slightly, nibbling momentarily on her bottom lip as she glances away. ‘I’ve never really had a lot of friends. I had a best friend once …’ Her voice trails away, and for a moment I don’t even think she remembers I’m here, and then her eyes are back on mine and she carries on, leaving that story untold. ‘But you know. Life.’ She shrugs. I think of my own scraps of friendships, and understand what she means. Circles grow small as we grow older.

      ‘I’ve met the partners’ wives and they seem very nice,’ she continues, ‘but they’re mainly quite a lot older than me. I’ve had lots of offers to help them with charity work.’

      ‘I’m all for charity,’ I say, ‘but that’s hardly like a good night out down the pub.’ I talk as if my life is filled with good nights out rather than quiet nights in alone, and I try not to think about my last good night out. You’ve kissed her husband, I remind myself. You cannot be her friend.

      ‘Thank God I’ve met you,’ she says, and smiles, before biting into her cake. She eats it with relish and I feel less bad about tucking into mine.

      ‘Do you think you’ll get a job?’ I ask. It’s partly selfish. If she wants to work with her husband then I’m screwed.

      She shakes her head. ‘You know, other than a few weeks’ work in a florist years ago which went terribly, I’ve never had a job. Which probably sounds a bit stupid to you, and it is odd and a bit embarrassing, but, well …’ She hesitates for a moment. ‘Well, I had some problems when I was younger, things happened I had to get over, and that took a while, and now I wouldn’t know where to start with anything close to a career. David’s always looked after me. We have money, and even if I got a job I’d feel like I was stealing it from someone who needs it and could probably do it better than me. I thought maybe we’d have children, but that hasn’t happened. Not yet, anyway.’

      Hearing his name from her lips is odd. It shouldn’t be, but it is. I hope she isn’t about to tell me how hard they’re trying for a family, because that might send me over the edge this morning, but she changes the subject, instead asking me about my life, and about Adam. Relieved to be talking about something non-David related, non-pregnancy related, I’m soon giving her my potted and not so potted history in the way that I do – all the openness, all too quickly – and making the worst parts sound funny and the best parts even funnier, and Adele laughs while I smoke more, and gesticulate as I race through my marriage
