Obsession: The bestselling psychological thriller with a shocking ending. Amanda Robson

       ~ Jenni ~

      ‘Why have you invited them midweek?’ Craig asks as he loads the dishwasher. ‘It’s my early shift. I’ll be exhausted.’

      ‘I’m worried about Carly. I need to talk to her.’

      ‘Because?’

      ‘She’s always been edgy – in a fun sort of way. But the balance has tipped. Now she’s just edgy.’

      ‘Well, it must be hard work being married to the local GP who works every hour that God sends, working herself, and bringing up three small children. So I do sympathise but’ – he shrugs his shoulders – ‘can’t you talk to her by yourself?’

      ‘I wanted to show her some hospitality. Hospitality at home. A deeper sort of friendship. You know how much she means to me. I can make dinner.’

      I kiss him and he pulls me towards him, wrapping me in his arms and holding me against him.

      ‘Can’t you put it off until next week? Give us a bit of time on our own when the children are in bed?’

      ‘I told you, next week I’m going to see my mother.’

      ‘Not again,’ he complains gently.

      I shrug my shoulders.

      ‘I don’t have a choice. You know that.’

      Our dinner-party menu. Beetroot salad, followed by spinach and ricotta lasagne – which took too long to make as I had to cut all the stalks off the spinach. The kitchen looks as if it has exploded; there are pans and cutlery across every surface, as I didn’t have time to wash up before Carly and Rob arrived. I’m not sure why I’ve bothered to go to all this effort as so far I’ve had no meaningful conversation with Carly. She is behaving in a way I’ve never seen before, spending her time weighing up Craig, her eyes all over him when she hasn’t noticed me watching. Carly. Wearing a low-cut top and too much make-up. She has gone for the smoky-eyes look. Carly. Laughing too loud at Craig’s blokey jokes, and every time she does so Rob looks embarrassed. Rob, clean-cut and sensible in his stonewashed jeans and carefully ironed shirt. Even Craig looks surprised at the depth of Carly’s laughter.

      I excuse myself and leave the room, walking back to our small galley kitchen to fetch dessert and put the kettle on for coffee. As I wait for it to boil, I look around at the culinary debris and sit on the low windowsill looking at the mess. Craig was right, entertaining like this is too much in the week. And he has to be up at five o’clock in the morning to start his shift at the fire station. He was recently promoted to leading fireman. I am so pleased for him. Craig, the only man I have ever loved. Unlike Carly, I haven’t had much experience with men. Craig is the only man I have slept with. I know that seems strange in this day and age of openness and overt sexuality, but it’s because of my religious convictions. My relationship with God. A relationship I am proud of. I don’t feel constrained or repressed because of it. God opens my life out.

      Craig and I met late, and so the time we have had together was almost immediately shared with the children, which is why we have to guard our relationship so preciously. It can be such a struggle to try and find each other between sleepless nights and children’s tantrums. So far at least, I think we are managing.

      But things are going to become more difficult.

      My mother has been diagnosed with ovarian cancer. Too late. As is all too frequently the case. When the consultant told her last week, I was there, holding her hand, looking into my father’s eyes.

      The kettle boils and I pour water on top of the freshly ground coffee beans waiting in the cafetière. I reach for the Eton mess I messed up earlier, and return to the party – followed by the fear of suffering and loneliness. Followed by my father’s eyes.

      Carly’s cheeks are slightly red and the tip of her nose is glowing.

      ‘Craig tells me you have to go on hospital duty next week without the kids. Can I be of any help?’ she asks as I serve her a generous portion of dessert. Perhaps a bit more food will sober her up.

      Rob stirs in his seat uncomfortably.

      ‘Have you run that by your mother, Carly?’ he says.

      She turns to him, eyes glazed.

      ‘Whatever do you mean?’

      ‘Nothing. Let’s talk about it later.’

      ‘I have other things in mind for later,’ Carly says, giggling and stabbing her fork towards a strawberry. She misses and bangs her fork onto her plate. Metal scrapes against china.

      Rob looks across at me, his eyes speaking to me – see what I have to put up with. I do not reply with mine, because after all, no one ever sees inside someone else’s relationship.

       ~ Rob ~

      The children are in bed. It took me an age to settle them. Carly, you are sitting in the easy chair in the kitchen, watching me cook a stir-fry with your piercing eyes of china blue. With your Marilyn Monroe looks and your volatile personality. Carly. So colourful. So challenging. You have put on a little too much make-up, as you always do just before I come home. Tonight it has smudged around your eyes.

      ‘Have you been crying, Carly?’ I ask.

      ‘No,’ you reply, taking a large slug of wine and crossing your legs, forcing me to admire a pair of shiny high heels I haven’t seen before.

      I stir the sweet and sour noodles.

      ‘Are you sure?’

      A flicker of the lines around your mouth.

      ‘Why?’

      I take the stir-fry off the heat.

      ‘Well, your make-up’s smudged.’

      ‘Are you criticising me again?’ you ask with a smile. An over-egged smile that doesn’t quite work. Carly, sometimes your smile frightens me.

      I serve the food into large china bowls and we sit opposite each other at the table, a lighted candle and the cruet between us. Without tasting my endeavours you take the salt and pepper and lash it across your food. I want to reprimand you. But I cannot. You are like an awkward teenager and I need to address one issue at a time. And tonight I have a more important mission. I take a forkful of food.

      ‘Carly, why did you slap Matt on the way back from Snakes and Ladders?’

      ‘He deserved it,’ you say violently. A pause. ‘Are you going to call the police?’

      ‘Of course not.’

      I lean across the table and put my hand on your arm. ‘I just want to talk about it.’

      ‘I’m not one of your patients, Rob. Leave me alone.’

      I remove my arm. We sit and eat in silence for a while. I can’t resist saying more.

      ‘Are you still cross with me about Jenni?’ I ask softly.

      ‘It shocked me that you want to fuck her.’ You emphasise the word fuck almost jubilantly; its guttural ending spitting out of your mouth.

      ‘Fuck her? When did I say that?’

      ‘That’s what you meant, isn’t it?’

      ‘You twisted my words. You pushed me.’ I pause. ‘Please, Carly, stop this. I love you.’

      Rob is in bed before me; he always is. I slide in next to him and he moves towards me across our silken
