I look at our neighbours gathered in the garden for our annual summer barbeque, sipping chilled wine and smiling at my two daughters sprawled on the grass. I go inside to help refill glasses and then I hear it. A shrill scream that stops me in my tracks. I race outdoors to silence, a sea of bewildered faces. My first thought is for my girls, but they are there unhurt. With relief, we push the chilling sound to the back of our minds, returning to our drinks and conversations like it never happened.

I take a sip of coffee as I plan my day. My surgeon husband, Cole, slept at work last night, so I had to get the kids ready on my own, again. I can’t complain, though, I’ve loved him ever since we met, long before he became a famous surgeon and the papers started calling him the pride of the hospital. Our latest family photo hangs on the kitchen wall and I remember that day so clearly. Cole screamed at me over nothing, then apologised saying he was stressed at work. My heart pounded with fear, but I plastered a smile on my face for the sake of my children.

I used to enjoy my job. I was good at it and felt fulfilled. I also used to enjoy spending time with the people I worked with. They say you spend more time with your work colleagues than you do with your family members, but that was fine by me because I made two very good friends at the office. I also allowed myself to get a little too close to my boss, but I soon realized that was a mistake. Unfortunately, it was too late by then, and as my personal and professional lives quickly blurred into one, that was when everything changed.

I’ve been married to my kind, loving husband Lachlan for over twenty years. He’s my everything. We have two teenage children, a beautiful home and I feel so lucky to live this perfect life. Until my best friend says something that makes me doubt everything… She whispers it’s strange Lachlan has lived nearby to two unsolved murder cases. First, the murder of the woman in the small, Scottish village where he grew up and more recently the shocking death of a woman who lived round the corner from us. The thought makes my head spin. It’s just a coincidence, surely?

When we move into the exclusive Westford Park housing estate, we feel safe at last. More like a country club, it has everything we might need – beautiful houses with big gardens, a pool, a boating lake, extensive grounds. It’s also got 24/7 security. Our new neighbours are lovely too. We start to make friendships that feel like they could last a lifetime. It feels like nothing could possibly go wrong here. It’s like our secrets haven’t followed us here. Or that’s what we think at first…

On the last day of school, my friends and I gather on the beach to celebrate the long summer ahead. Sipping cans of warm cider and watching campfire embers dance into the inky sky, I don’t think I’ve ever been happier. Until a scream pierces the night. The next morning, we find shy newcomer Pippa on the beach, sandflies gathering on her lifeless body…

Alex and I haven’t been dating for very long when I go to his place for the first time. Feeling self-conscious as I notice a thread coming loose on my dress, he pours me a glass of wine and I take in the pristine room and expensive furnishings. Everything here is perfect, too perfect. Where are the personal touches, the souvenirs from his life? Where are the photos of his friends and family? ‘You can trust me,’ Alex says as he hands me the wine, and my heart beats wildly in my chest. I really want this to work, especially after the disaster of my last relationship.

Emily has the perfect life. The perfect husband. The perfect daughter. But she also has the perfect secret. One that could destroy everything she holds dear... one that could ruin her.

I’ve never felt welcome in my husband Dominic’s family home. His parents make it clear I’m a poor comparison to his perfect first wife, Carla. But we’re here for Christmas, so it’s important to pretend everything is fine. Until Dominic’s mother bustles into our bedroom. Smiling thinly, she blindsides me: ‘You won’t mind, will you. Carla is coming for the holidays. She’s still one of the family to us, and she can’t get home because of the storm.’ My eyes widen—did she and Carla plan this on purpose? I know Dominic won’t say a thing. He never stands up to his parents.

She knows everything about you… but can you trust her? I walk in to my interview with Ava Green and carefully hand over my application. It’s all made up, of course, but Ava doesn’t have to know that. There is so much worry in her blue eyes. Her phone pings with constant messages and a small stain marks her crisp shirt. Breakfast with her two little girls before heading out to this high-flying job every morning can’t be easy. Ava needs me, I think. More than anything.

My wedding was the perfect whirlwind of a day. The happiest I’d ever been. That was until I discovered my beloved husband, Ryan, tucked away in a compromising summer house clinch with Liza, his best friend’s wife. Reeling with this ultimate betrayal, my world in freefall, with nowhere to turn, I flee my own wedding unable to face anyone, not even my family. I just want to escape this nightmare. With our flight, to our luxury honeymoon leaving in a matter of hours, could ten blissful days of Cretan Island life, minus my cheating husband help me figure out my future?

How well do you really know your own family? The wife: Eve is desperate for her life to be perfect. Living in a beautiful house, with gorgeous views of the countryside, is all she’s ever wanted. And she’ll do whatever it takes to hold onto her dream life. The son: Joe is a model student; he never puts a foot wrong. He knows his mother wouldn’t tolerate it. Until the night of his sixteenth birthday party, when things go horribly wrong and someone in the house is left fighting for their life. As the blue flashing lights of the police and ambulance arrive, all eyes are on the Griffiths family.

Some secrets refuse to stay buried... Abandoned by her mother, Lucy Mitchell grew up in foster care, where she found solace in her best friends, Amber and Josh. In a strict foster home, Lucy and Amber made a pact – friends for life – often escaping to the woods to hide from their overbearing carer, Linda. Then, one day, only one of them comes back. Amber was gone, leaving behind only a note: I’ve run away. Fifteen years later, Lucy is planning her dream wedding to Josh – until a body is discovered.

Should I believe the woman who ruined my life, or protect the husband who’s already betrayed me? I walk past rows of immaculate white roses into the Kane family’s picture-perfect home, thinking that I’d never guess what’s happened behind closed doors. The woman standing with my colleagues in handcuffs looks so innocent in her blue, silk dress. But they say she’s killed her husband. When I see her face, I recognise her immediately. She’s my own husband Bradley’s mistress… She was found beside the body with blood on her hands.

Charlie takes my breath away from the moment we meet, when he is dropping his adorable little girls off at the school gates at the same time as I’m waving goodbye to my son. Being a single mother has been hard. So when his gorgeous green-blue eyes hold mine and his lips curve into a smile I wonder if this is my chance to find happiness and escape the secrets in my past.

Fiona Fisher lives a quiet and contented existence. A former nurse who married Jason, the doctor of her dreams, she is now a mother to his two daughters and living in the sort of cosy village home she’d always wished for.

Wife: I couldn’t be prouder of my charming husband and quiet and kind son. I’ve poured everything into my little family, so I choose to ignore my husband’s late-night phone calls and wandering eye. I won’t let anything ruin my perfect life…

‘I’m sorry, Sam’s not available,’ says the woman who answers my husband’s phone. I can’t place her voice, so I politely ask who she is. Her answer sends my world spinning out of control: ‘I’m his wife.’

Carly had thought they’d always live there. The beautiful Cornish cliffside house they’d taken on as a wreck, that Mark had obsessively redesigned and renovated - a project that had made him famous. It was where they’d raised their children, where they’d sat cozily on the sofa, watching storms raging over the sea below. It was where they’d promised to keep each other’s secrets. Until now. Because Mark has fallen in love. With someone he definitely shouldn’t have. Someone who isn’t Carly. And suddenly their family home doesn’t feel like so much of a safe haven.

I’ve never felt welcome in my husband Dominic’s family home. His parents make it clear I’m a poor comparison to his perfect first wife, Carla. But we’re here for Christmas, so it’s important to pretend everything is fine. Until Dominic’s mother bustles into our bedroom. Smiling thinly, she blindsides me: ‘You won’t mind, will you.

My handsome husband Tom. You've given me everything our beautiful son and our perfect new seaside home. I want to trust you, but I know you haven't been honest about why you really wanted to move here. I haven't been honest with you either.

But who was the man who died driving Tate’s car? How did he have Tate’s possessions and, more importantly, why do they sport identical tattoos?
