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…

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.

I stare at the messages between my husband Rob and another woman, their plans to run away together bringing tears to my eyes as I stand, trembling, in our luxurious apartment. I thought I had the perfect marriage. As our three beautiful children sleep soundly in the next room, I think about our family holidays, our romantic date nights, and the day Rob proposed to me. In the last few months, I haven’t complained about his late-night meetings or got jealous about his weekends away. I trusted my husband. But now I’m questioning everything.

I thought he was dead. Until I saw him staring back at me… Ten years have passed since my beloved sister was murdered, leaving behind her sweet five-year-old daughter, Lily. I’m trying my best to care for Lily and salvage what’s left of our shattered family. I promised to keep her safe after all she’s been through, and after a lot of challenges, I hope she might be starting to lead a normal life again. But then I see a face in a photo I took just yesterday that turns my blood to ice.

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.

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.

Standing in my bathroom, the luxurious marble tiles cool under my feet, I stare at the test in my trembling hand. The second line is unmistakable: I’m pregnant. This is all my husband Theo and I have ever wanted, but I didn’t think it was possible. I should be excited, but all I can think about is telling my stepdaughter. Because Ellie’s always hated me, ever since she realised it was no longer just her and Theo. Now she’s seventeen, beautiful and smart–smart enough to see through me. And if Ellie decided to uncover my secrets, it wouldn’t be just my marriage at stake… it would be my life.

When you return from a work trip to find your husband dead in the pond, it’s best not to call him a liar and a cheat in front of the cops. Especially when you’ve spent the last few years telling anyone who’ll listen that you sometimes fantasize about killing him. It makes you look kind of, well, guilty.

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?

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 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.

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.

The letterbox clatters and sitting on the mat is a piece of paper, in black and white, with everything needed to blow Anna’s perfect life apart. A baby scan photo. Anna and Jon have been trying for a baby with no success, so after years of disappointment, this feels like a kick in the teeth. Who sent it? And why?

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?

After my first husband died, I thought my heart was completely broken, and that I’d never feel happy again. Until I met Theo. He’s a doctor. A man who seems good and caring and kind. Soon after we start dating, he says he wants to marry me. And even though his grown-up children are less sure about me, to everyone else it’s the second chance for love and happiness I deserve. But the truth is maybe his children are right to be suspicious. Because I know something about Theo. That he was there in the operating theatre the day my first husband died. And I think it was his fault.

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 was so nervous about someone new joining our house share. After everything that happened with my parents, my friends are like my family. Our imperfect, but well-loved house is the only place where I can be myself. But when Poppy knocks on our door, blonde hair, wide eyes, and a friendly smile, we all agree she’s a perfect fit. I just wish I could shake the feeling that I’ve seen her before…

I am on my way home, thinking only of the quiet, happy evening to come, when I see something completely impossible, and my heart stops dead. I would recognise those gorgeous pale blue eyes anywhere. It’s him. The high-school boyfriend I adored… Until the day he vanished without a trace. I run towards him, my pulse racing. He turns, politely, a puzzled look on that familiar face. ‘I’m sorry,’ he says. ‘Do I know you?’ I need answers. I’m certain he’s lying. I just have to prove it.

‘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.’

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?

I push open the door to the beautiful French villa and my clever, handsome husband and adorable wide-eyed children follow me inside, taking in the breath-taking view. This should be a blissful summer break, filled with sun, swimming and relaxation but the truth is very different. Because my husband has just revealed the real reason we’re here. When our friends staying at the sprawling villa greet us on the sun-soaked terrace, I smile brightly and attempt to calm my nerves.

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…

All she wanted was the truth, but she'll wish she never found out. When Catherine wakes up alone one morning, she thinks her husband has gone for a run before work. But Simon never makes it to the office. His running shoes are by the front door. Nothing is missing - except him.
