1

It’s a Tuesday in mid-August when I get the call. Ben has kept me up half the night and I’ve come to the office with his lunchbag (pureed carrot and ricotta, Marmite soldiers, Peppa Pig yoghurt), while he’s at nursery with mine (tuna bean salad and fizzy water). It’s eleven thirty when the phone rings, and I’m playing the game I play where I divide the day into manageable quarters. I’ve already made it from breakfast to the mid-morning crime team diary meeting and, by lunchtime, I’ll be halfway there. There will only be another two quarters of the day – I can’t even begin to think of it as a fourteen-hour stretch; that’s way too long – until I can crawl back under the duvet and close my eyes, even if just for a while.

I pick up the phone. Lucy, our receptionist, says, ‘Annalise Finch for you,’ and then she’s gone.

‘Sarah! How are you?’ Annalise speaks earnestly into the receiver, with an emphasis on the ‘you’. She waits for an answer (which not everybody does).

‘Yeah, good. Good,’ I tell her, and then I feel the bitter sting of tears. This is my latent, Pavlovian response to any gesture of kindness towards me, no matter how small. Annalise is an ex-work colleague, but I also think of her as a friend. Do I tell her that I haven’t had a decent night’s sleep in months? That my head is throbbing and my eye sockets ache? Do I warn her that I’m scared to open my mouth and talk, on days like today, for fear of jumbling up my sentences or dropping nouns?

I know Annalise well enough to know that she’s not the sort of person that judges you, and besides, she’s a woman who has had small children, so she’s halfway to knowing what this is like. Although her children are ordinary, regular children, of course. Her children are normal. I wonder, fleetingly, whether I will ever be able to think about another woman’s ordinary, regular children without feeling overwhelmed with grief and pain.

‘Sarah?’ she asks. ‘Are you still there?’

‘Sorry. Yes,’ I tell her. ‘How are you? It’s nice to hear from you.’

It is. I had forgotten how much I liked Annalise, or Anna as I’ve always known her at work. She’s a family lawyer. She gets called a divorce lawyer but that’s not really what she does. She deals with child custody, mostly, specifically public law cases, the ones where there are child protection issues and the local authority want to take the child away. We used to see each other at the local magistrates’ court sometimes when we both worked at Cartwright & Taylor, and when we were both there late, as we often were, we would stop off for a drink on the way home.

Of course, that was before Ben. I don’t get to do things like that very much these days, but I’m happy to hear a friendly voice on the phone, the voice of someone with whom – on a day like today, when I’m feeling at my very most mortal – I don’t have to pretend to be the sort of professional superwoman that I’m always reading about in the Law Society Gazette.

‘I’d love to chat,’ Anna says, ‘but, listen, I’ve got a case for you.’ Her voice echoes a little down the receiver. I’m guessing I’m on speakerphone. ‘It’s serious. It’s an attempted murder. Of a child.’

And then she’s off, talking rapidly, and I’m missing what she’s said. I reach for a pen, grabbing the notebook that’s on the desk in front of me and finding a fresh page. As I do so I nudge my coffee cup and a stream of light brown liquid leaps over the rim and across the desk. I’m instantly overwhelmed with the urge to either punch somebody or throw myself out of the window, the small puddle of coffee in front of me magnified by lack of sleep into Atlantic proportions. Instead I tuck the phone under my chin, pull a pack of baby wipes out of my handbag, take out a handful and drop them, one by one, onto the desk.

‘You’re really the best person I can think of for this,’ Anna is saying.

‘I’m really sorry, Anna,’ I interrupt her. ‘I didn’t catch all of that. Would you mind starting again?’

‘Oh. No. Of course not.’ She picks up the phone, and her voice comes into focus. ‘It’s one of my clients. She’s accused of trying to kill her eleven-month-old baby. Her name’s Ellie. She’s a young mum – twenty years old. Cut a long story short, she’s poisoned him. Then, while he’s in hospital recovering, she’s gone onto the ward and tried to kill him again.’

‘Jesus. How?’

‘He was on dialysis after his kidneys failed. She pulled out the tube – the line, they call it – that took the blood out of his body and into the machine, and of course the machine just kept pumping the blood out of him. She covered him with a blanket to hide it. He nearly bled to death.’

‘Jesus,’ I say again. ‘What’s the evidence that it was her?’

‘Well, no one saw it happen. But she was there when they found him. She was asleep on a camp bed beside him – or pretending to be; that’s what the police are saying. A nurse spotted a pool of blood under the cot. He’d lost around a quarter of it, gone into heart failure. They managed to resuscitate him, but he’s still in a critical condition.’

‘Which hospital is it?’

‘Southwark St Martin’s.’

I feel a sharp jolt of pain. St Martin’s. The same hospital. I throw the bundle of soggy wipes into the bin under my desk and sit back in my chair. I can see the ward; I can feel the heat of it, smell the antiseptic air. I can see the cot and the blanket – white, crocheted with a blue and white Southwark St Martin’s trim. I can see the baby, pale and still. I can picture it all, as if I’m there.

‘Also, he was with her when he was poisoned,’ adds Anna.

I pull a fresh notepad from my drawer. ‘How was he poisoned?’

‘Salt.’

Salt?

‘Yep. It causes a potentially fatal electrolyte imbalance. It’s called hypernatraemia.’

I think about this for a moment. I think about Ben. ‘How do you force salt into a one-year-old?’

‘I don’t know. But somebody did. And he was with her. Ellie. She’d had him overnight, unsupervised, for the first time in months. He was in care at the time. He’d already been taken away from her.’

‘Why?’

‘They found injuries. Bruises – and burns – when he was around eight months old. That’s how I got her case. Although we managed to fight it that time. Our expert report was favourable; it said that no one could be certain that the injuries were non-accidental. She was well on the way to getting him back again, but then he’s admitted to hospital with what they think is a virus, which turns out to be sodium poisoning.’

‘And they left her alone with him, in hospital?’

‘They knew he was seriously ill, but they didn’t know he’d been poisoned at that stage, not until the tests came back.’

Anna pauses. My pen hovers above the page while I take this in.

‘I’ve got to admit, it doesn’t look great for her,’ Anna says. ‘The prosecution case is that the three separate incidences of harm combine to build an overall picture of deliberate abuse. They each support each other. It all kind of stacks up. And Ellie... well, unfortunately, she doesn’t come across well.’

‘Why? What does she say?’

‘Oh, she denies it – all of it. Says she’d never hurt her baby. But she wasn’t great in interview. She can’t explain how it happened, any of it, other than to say it wasn’t her. She doesn’t... well, volunteer information. She just gets angry and then clams up. I know she’s scared. She’s a “looked after” kid herself – she grew up in a care home in Stockwell – and she’s like many of our young people: naturally reticent and suspicious of the authorities. She has no faith that anyone is going to believe her side of things. But it comes across the wrong way. She appears... overly defensive. And secretive, as if she’s hiding something.’

‘What’s her previous?’

‘Thefts, cars and stuff as a youth. Peer pressure probably. Nothing like this, and nothing for a while.’

‘So, when’s the first hearing?’ I look up as the door opens and Matt, my colleague, walks in. He takes off his coat and sits down at the desk next to me. I flash him a smile. He purses his lips and switches on his computer.

‘That’s the thing,’ Anna says. ‘It’s been and gone. The case has been sent to Inner London Crown Court. She’s been remanded to Bronzefield. There’s a bail hearing tomorrow.’

‘Tomorrow?!’

‘I’m sorry, I know it’s short notice. But I was on holiday when they arrested and charged her. We went to Sri Lanka, Tim and I and the girls, for a fortnight. I didn’t find out until I got back into the office this morning.’

‘Sri Lanka. Wow. Sounds wonderful.’ I can’t help feeling a stab of envy; I can’t take those sorts of holidays any more.

‘Look, are you OK with this?’ Anna asks me. ‘I mean, I did think about it, that it might drag stuff up for you. But that’s why I also think you’d be the best person to take this on. You spent a lot of time in hospitals when Ben was small. You know what it’s like to have a sick child.’

‘Yes, I... it’s fine. Really,’ I say. ‘I want to do it.’

‘Oh, good,’ Anna says, pleased. ‘Ellie asked for the duty solicitor at the police station and again when the case was allocated to the Crown Court, but she wants to instruct you, on my recommendation. I know you’ll need her at court, so I’ve asked for her to be produced. She’ll sign an authority to transfer tomorrow, and she’s happy for us to talk to each other about her case. I’ve some papers I can give you. I’m going to have to go now, I’ve got a client waiting, but we can meet for lunch, if you like?’

We arrange to meet at a quiet pub off the beaten track in Gray’s Inn Gardens. I don’t normally take a proper lunch break; I don’t normally have time. But this is about work, and it’s good to have an excuse to see Anna. Besides, I don’t have much appetite for whizzed up carrot and ricotta.

Oh my God. I grab my mobile. Ben’s lunch. I still haven’t called the nursery to explain the mix-up and to ask them very nicely to find Ben something from the kitchen, just for today. I meant to do it an hour ago. But I also have to book Counsel for tomorrow; it’s short notice as it is and people are away on holidays. I force my brain into action. Which to do first?

I glance at the luminous white digits on my phone before scrolling through my favourites and finding the number for the nursery. It’s eleven forty-five. They’ll be OK about this. They’re bound to have a spare yoghurt. What else? I rack my brain. Fruit. They always have fruit. He can eat soft fruit. Melon and banana and stuff. Oh, God – they won’t try to give him my tuna bean salad, will they? But they know. They know, Sarah, I tell myself. Stop worrying. They won’t let him choke.

The day manager, Lisa, answers. I love Lisa. Really. I actually love her. She’s my hero and my saviour and the only person, apart from Helen, his keyworker, who has spent enough time with Ben to know him the way that I do. She reassures me with calm efficiency that they won’t let Ben choke or starve, and that he’s had a really good morning, most of which has been spent spinning the wheels of an upended dolls’ pram.

I thank her profusely, tell her I’ll see her at six, and then locate the number for 5 Temple Square Chambers. Kevin, the clerk, tells me that Dan Bradstock – who would have been perfect for this case – is booked out on a five-day trial at the Bailey but that Will Gaskin – do I know Will Gaskin? – is at ILCC tomorrow with other cases, if I want to give him the brief?

‘Yes, I know Will,’ I say, pleased. ‘Thank you. I’ll email you the papers this afternoon.’

When I put the phone down it immediately rings again. It’s just one long ring, which means it’s an internal call. It’s my boss, Gareth. ‘Can you pop in?’ he asks.

‘Sure.’

I walk down the corridor to his room and tap on the door. He stands up to greet me and pushes the door closed. I know immediately, instinctively, that something is wrong.

He waves me into a chair. ‘Sit down, Sarah.’

I do as I’m told.

‘I’m not going to beat about the bush,’ says Gareth. He crosses and then uncrosses his legs, and then swings round in his chair to face me. He leans forward. ‘The thing is, there have been complaints about you.’

My heart leaps. ‘Complaints? From who?’

Gareth sits and looks at me for a moment. He takes his lower lip between his teeth and sucks it.

‘Was it Robin Crowthorn?’ I ask. ‘You know he has schizophrenia? I spent ages trying to calm him down yesterday, but he’s not well. He wants me to take a civil action against the police. He thinks they’ve got him under surveillance via a microchip in his brain.’

‘It’s not a client.’

‘It’s not?’ I’m genuinely baffled now.

‘Look, the fact is that your billing is twenty per cent lower than the others in your team. They feel they’re carrying you, that you’re not pulling your weight.’

‘What?’ I’m genuinely astonished to hear this. ‘Matt?’ I ask. ‘Matt’s complained about me?’

‘Not just Matt.’

‘Well, who?’

Gareth sighs and licks his lips. ‘I’m told you’re on the phone to your... your son’s nursery a lot. And that you took a long personal call this morning.’

Lucy. I take a deep breath, in and out, before I answer. ‘That was about work. It was Annalise Finch. She’s just given me a new Crown Court case. It’s an attempted murder. Of a baby.’

Gareth looks up at me. ‘Really?’

‘Yes. There’s a bail hearing tomorrow. I need to be there. Sorry, but someone else will need to cover the magistrates’ court.’

I watch his face as his eyes first express interest and then narrow slightly. ‘Are you sure you’re the best person to take on another Crown Court case?’ he asks. ‘I mean... well, it might be better if we sent Matt along instead.’

I feel my jaw drop. I look up at him. ‘What? Why?’

‘Because the case will be time-consuming and...’ Gareth looks uncomfortable. ‘And it’s clear that you have other priorities.’

To my horror, I can feel myself starting to cry. I know that it’s lack of sleep that’s to blame, that I’d be more robust if I hadn’t been up half the night. I turn my face towards the window and blink hard. I say, ‘They bill twenty per cent more than me because they go to the police station at night. I can’t do that.’

Gareth picks up a pen and taps it against his desk. ‘I think that’s part of the problem.’

I glance down at my lap and blink hard again. ‘I’m sorry. But I have Ben. I can’t...’

‘Do you not have a family member? Someone who could...’

‘No.’ I shake my head. ‘There’s no one I can ask.’

‘Then, a babysitter? And, before you say anything, I know it would cost you more than you’d earn. But if you could just show willing... If you were on call a few nights per month, plus one weekend, maybe, it would keep everyone happy, show you were doing your bit. What do you say?’

‘It’s not that simple,’ I tell him. ‘My son has special needs.’

Gareth’s face is impassive. ‘Sarah, I’m aware that you’ve got... personal difficulties. But, at the end of the day, we all have busy lives. Everyone’s got their problems.’

I don’t know what to say to that. I sit and look at him for a moment. ‘It’s hard to explain,’ I say. ‘But... but trying to get someone to look after him who... someone who can deal with him... I don’t know anyone who... but that doesn’t mean that I don’t work hard. It doesn’t mean I can’t do my job.’

Gareth sighs. ‘Well, if you can’t go to the police station out of hours, you’re going to have to manage your time better.’

I open my mouth and then close it again. Gareth surveys me in silence.

‘She gave the case to me,’ I say, finally. ‘I’m aware that Matt wants a shot at something bigger, but this is about doing what’s right for the client. For Ellie.’

Gareth looks me in the eye for a long moment. ‘OK. I’ll send Matt to the mags tomorrow. But you’ll still have your other cases to run. So, do whatever you have to do to make up the time. You see your client, you take instructions, you say goodbye. The Robin Crowthorns – you bin them off. Send them away.’

‘That’s easier said than done,’ I object. ‘He’s in a bad way. In his mind, he’s being watched and followed. He’s frightened.’

‘We’re not social workers, Sarah. We don’t get paid to deal with that kind of stuff. Times are hard. It’s the way things are.’

I stand up. ‘Is that all?’

Gareth says, ‘Yes. For now.’ As I reach the doorway, he calls my name. I turn to face him. ‘A baby, you say?’

‘Yes. Eleventh months old.’

Gareth narrows his eyes again. His tone is far from friendly when he says, ‘Just don’t get too involved.’

*

When I arrive at the pub, Anna’s sitting on a dark green leather sofa. She stands up to kiss me and I hug her tall, thin, somewhat bony frame. She’s almost the polar opposite of me, with her olive skin and her slim hips; I’m shorter, fair-skinned, blonde and just a little too curvy. But she’s naturally thin, it seems; she’s not one of those waif-like model types that never eats. On the contrary, she loves food and loves to cook. I remember her being addicted to Masterchef and bringing me delicious soups and stews into the office, wrapped in tinfoil, several times a week. That was my evening meal sorted out, more than once. It helped more than she knew. Or maybe she did.

Today, she’s wearing a grey trouser suit and – since I saw her last – she’s had her curly jet-black hair straightened and cut into a pretty bob.

‘It suits you,’ I say, nodding at her hair. ‘It’s lovely.’

‘Thanks.’ Anna sits back down again, stretches out her long legs and crosses her ankles.

‘Nice suntan,’ I add, smiling. ‘I’m extremely jealous. You look amazing.’

Anna looks up and smiles. She can’t say the same back to me because I look like shit. Instead, she leans forward and pulls out the menu from a dark wooden cradle on the table. She chooses coffee and a cheese and ham panini and I tell her I’ll have the same. She goes up to the bar to place our order and I lean back into the soft leather folds of the sofa and close my eyes. I instantly feel the stress and tension melting out of me. The leather feels amazing under my legs and up against my back – it’s cool and refreshing, a stark contrast to the heat of the August sun outside. I want to curl up into a ball and put my feet up and to never have to get up again.

I feel the sofa move slightly against the pressure of Anna’s body as she sits back down beside me. I open my eyes and sit up slightly.

‘You were asleep!’ she accuses me, laughing.

‘No. Just resting my eyes.’ I smile. But I think I was asleep.

She leans over and lifts a wisp of hair from my face and tucks it behind my ear. ‘Don’t take this the wrong way, but you look completely exhausted.’

‘It’s Ben,’ I sigh. ‘He just doesn’t sleep. He goes down OK, but then he’s up again a couple of hours later. The minute he wakes, he thinks it’s time to get up and then that’s it until dawn.’

She pushes a cup of coffee across the table towards me. ‘How old is he now?’

‘He’s nearly five. He’ll be starting school in September.’

Anna reaches out and touches my hand. ‘I wish I could tell you he’d grow out of it, but I know it’s not that simple with Ben. Is there no one who can help? Give you a bit of a break for a night or two?’ she asks.

I shake my head. ‘Not really. I don’t really have any family nearby.’

‘I could have him one night if you like,’ Anna offers. ‘I don’t mind.’

‘That’s sweet of you, Anna. I may just take you up on that.’ I know that I won’t. It’s too much to ask of her. ‘So, tell me about Ellie,’ I say.

Anna opens her briefcase. She hands me a plastic wallet with a charge sheet, police summary and conviction history inside.

‘This all you’ve got?’ I ask.

‘So far. Sorry, I can’t disclose the papers from the family proceedings,’ Anna says. ‘Not without the judge’s permission.’

‘Of course.’ I glance at the papers. ‘So. Her name’s Ellis. Ellis Stephens.’

‘Yeah. Calls herself Ellie. She has no family. She was an only child; her parents were drug addicts and she was removed from them as a baby. She’s spent most of her life in care and, despite her young age and the hand she’s been dealt, she hasn’t done badly. She seems to manage her life well enough. She works, she pays her rent, she stays away from the wrong people. Considering she’s been through so much and has virtually no support network...’ She pauses and glances up at me. ‘She’s doing far better than some that I know. And although history appears to be repeating itself, with the child being taken away... well, she’s still here, fighting to clear her name, fighting for her son. It would be too much for a lot of people, going through all that alone.’ She takes a pack of sugar from the table, tears it open and tips it into her cup. ‘On the other hand, of course, it’s the perfect storm.’ She picks up a spoon and gives her coffee a vigorous stir. ‘She has the textbook profile of a young woman who harms her child. That’ll be the prosecution case, for sure.’

‘So how’s the baby doing?’ I ask her. ‘Will he live?’

‘It’s touch and go. He’s in a critical condition. He’s had a blood transfusion, but there are still problems with his kidneys. The blood loss caused his heart to fail. There are other complications as a result.’

‘So the charge could become one of murder?’

Anna bites her lip and nods slowly.

I glance back down at the papers in front of me. ‘So the baby’s name is Finn. And what about the father? Is he around?’

‘Kind of. His name’s Jay. He’s older than her and from quite a well-to-do family: the Barrington-Browns. Old money. Father’s a life peer and mother’s from a family of doctors. Her father’s an Old Etonian, a fellow of the Royal College of Surgeons. Their backgrounds couldn’t be more different.’

Anna pauses as our food arrives. The waiter leaves and returns again, bringing napkins, ketchup and mustard.

‘They met at a party, apparently, at a hotel in Chelsea. Ellie was working there as a waitress for a catering company and Jay was there – having a good time, it seems. He took a shine to her, she stayed the night, and the rest is history. They went out a few times, but it looks as though their relationship was fairly short-lived. I don’t know whether he ever actually cared for her, but I don’t think she stood a chance with him, to be honest. The Barrington-Browns own a ten-million-pound house in Richmond. Jay has a flat in Markham Square, Chelsea. Ellie, meanwhile, lives in a housing association flat in Camberwell. It was all pretty much stacked against her.

‘But then she fell pregnant. When she told Jay, she says she had no expectations, other than that he’d help her financially. She thought he’d want her to get rid of the baby and she says she considered it, but after the initial shock had worn off he seemed keen to help her bring up the child, or at least to do his share. All seemed fine for the first few months. Finn appeared to be thriving, no one reports any concerns. Then, when he’s around eight months old, Finn gets a chest infection and is admitted to hospital. The A&E nurses find a number of bruises and what appear to be cigarette burns. Social Services get an emergency protection order and Finn’s taken away while they investigate. Ellie’s got no family and Jay works long hours, so Finn’s gone to the grandparents – Jay’s parents. That’s when Ellie came to me. We spent the next three months working hard towards getting Finn back. We had a bit of a fight on our hands for a while. Ellie didn’t get on with her social worker.’

‘Heather Grainger,’ I say, referring to the papers in front of me. ‘She’s one of the key prosecution witnesses.’

Anna nods. ‘Ellie will tell you that Heather had it in for her, right from the start.’

‘And did she?’

Anna looks at me and wrinkles up her nose. ‘No. I don’t think so. She’s a professional. She wouldn’t let things get personal.’ She leans back in her seat. ‘But, to be fair to Ellie, Heather’s not the most sympathetic of people. And she goes by the book. She can be a bit... prescriptive.’

‘You mean, controlling?’

Anna laughs. ‘A little.’

‘So they clashed, basically.’

‘Well, yeah. Heather was “on her case all the time” as Ellie saw it – which, of course, she was. Quite literally. Ellie, in the meantime, was highly defensive, said she’d done nothing wrong. There was a bit of a battle of wills.’

‘Over what?’

‘Oh, the usual stuff. Prop-feeding, co-sleeping – things that are probably normal to most of the mothers on the estate where Ellie lives. Ellie was willing to be educated, but not by Heather; she came on too strong.’

‘But she got Finn back, didn’t she? She must have done something right?’

Anna nods. ‘Like I said, Social Services couldn’t prove definitively that the injuries had been deliberately inflicted. Ellie learned to toe the line. We were at the stage where she’d been given unsupervised contact a couple of times per week. And then she gets to have him overnight, for the first time.’ She takes a sip of her coffee and looks up at me. ‘But something happens during the night. When Heather turns up in the morning, Finn’s seriously unwell. He’s awake and conscious, just, but not moving. He’s floppy and his eyes are glazed. She can see straight away that there’s something really wrong. She calls an ambulance and he’s rushed back to hospital. He’s vomiting and having seizures on the way.’

I feel a familiar knot in my gut, a tightness forming in my chest as she talks. I breathe in deeply and hold it there for a second or two. Anna pauses for a moment and looks up at me, her face softening.

‘Carry on,’ I say.

‘They didn’t know what it was at first,’ she continues. ‘They knew that his blood sodium level was high, but presumed he was dehydrated. They suspected meningitis, or some kind of virus, until the tests came back. Meanwhile, Finn has been treated, he’s turned a corner and seems to be on the mend. He’s released from the ICU to the renal paediatric unit – Peregrine Ward – where he’s having treatment for the damage the sodium has done to his kidneys. So, it’s his first night on Peregrine Ward. Ellie arrives – she stays the night. Nurses on the evening shift all say that Finn was fine when they left. Then one of the night shift nurses spots a pool of blood on the floor under his cot and there’s Finn lying there, unconscious and bleeding heavily, with Ellie asleep on a camp bed next to him, or so she says. She says she woke up to a commotion, the nurse calling for the doctor. She swears she knew nothing about what happened.’

‘And no one saw anything?’

‘No. Except one nurse, apparently, who says that as she was going off shift at around ten p.m., she saw Ellie leaning over the cot and picking up the baby. That’s all they’ve got. But someone disconnected his tube not long afterwards, and as Ellie was the last one seen with him... and she was there, right next to where he was found... the doors to the ward are security protected, they’ve viewed the CCTV and say no one else came in or out. Then the tests come back showing these hugely elevated sodium levels in his body at the point he came into hospital... and well, with everything put together, they obviously believe they’ve got enough evidence to convict.’

I sweep up a few stray crumbs from the table and fold them into a napkin. ‘Is there... any way the baby could have dislodged the tube himself?’

Anna shakes her head. ‘The hospital say no. He was still sedated from the operation.’

‘What about the nurses? Is it possible that the tube hadn’t been taped in place properly?’

‘Well, I suppose it’s possible, but the nurses say they’d left him uncovered, in line with procedure, so that they could see the exit site of the line at all times. Someone had covered him with a blanket. The medical tape had been completely ripped off. That, combined with the position of the tube when they found him, has led the doctors to believe it was deliberate.’

I look up. ‘Well, they’d be bound to say that, wouldn’t they? If the hospital had allowed an accident to happen, they’d hardly admit it.’

Anna looks doubtful. ‘St Martin’s is a leading paediatric hospital,’ she reminds me.

I nod. ‘It’s where Ben was. They’re brilliant there. But it only takes one person to make a mistake.’

Anna presses her lips together. ‘But then there’s the poisoning too. How do you explain that?’

I think about this for a moment. ‘Was he definitely poisoned?’ I ask. ‘Are there other reasons why a baby’s sodium levels might be high?’

‘Possibly. But he was really sick when he came into A&E. He was fitting. He nearly died.’ Anna glances at me. She’s still wondering if I’m OK with this.

I give her a wry smile, to reassure her. ‘Well, there are a lot of things that can cause a seizure.’

Anna shrugs. ‘Of course.’

‘Look, I’m the last person who would want to criticise the nurses or point my finger at the hospital,’ I tell her. ‘Not after everything they did there for Ben. But I’d have to explore that as a potential defence. If Ellie says she didn’t do it, any of it, then it’s my job to find out who did.’

‘Sure.’ Anna looks at me and her nose twitches.

‘Things aren’t always as they seem,’ I say. ‘Especially when it comes to children.’

Anna takes a last bite of her panini, chews and swallows it and then picks up her coffee cup. ‘That’s why I wanted you on this case.’

I study her face as she takes a sip of her coffee. I notice that Anna wears no make-up other than a thick line of navy eyeliner, which streaks across her eyelid and up at the corner. Dark lashes frame her almond-shaped eyes.

‘But you don’t believe her, right?’ I ask, shaking my head. ‘You think she did it?’

She sips at her coffee and peers at me over the rim of the cup. Her dark eyes meet mine. ‘Persuade me otherwise,’ she says.
