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.

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…

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 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.

I thought my first husband died ten years ago. But now he’s back... Opening the front door, I’m stunned to see a familiar face. I never thought I’d see Freddie’s deep brown eyes and crooked smile again. But how is this possible when he died ten years ago…? It took years to move on, but finally my life is almost perfect.

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 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.

Alicia’s been telling lies. And now, they’ve come back to haunt her. When an old colleague turns up at a party, Alicia comes face to face with the man who has the potential to ruin her perfect family life. He wouldn’t, would he? In order to keep her secrets, Alicia has to tell yet more lies, and when a devastating car accident makes the situation even more dangerous, it’s only a matter of time before everything falls apart. Can secrets really stay hidden forever?

Caroline twitches aside her curtains to see the new family moving in. A mother – beautifully dressed in expensive clothes – and two young children. Where is her husband, she wonders? And why are they moving in to the smallest house on the street? They really don’t seem the type. But Caroline believes it’s important to be welcoming. It’s important to know everything that’s happening on West Street.

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 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.

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.

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.

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.

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.

My mother is obsessed with every detail of my wedding–controlling my dress, my ring, my happiness. But when the day finally comes, will she really let me go?

ME: Staring down at the sweet baby in my arms, I feel panic instead of love. Because this isn’t the child I gave birth to. My husband whispers to the midwife. They all think I’m going crazy. But the tiny boy in my arms is crying again. I’m certain: he knows I’m not his mummy. And I’ll do whatever it takes to get my son back.

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?

Maddie and Kiara have been best friends since they met on their first day at university. They have always shared everything with each other--everything except one big secret, which Kiara knows would tear them apart…. When the police knock on Maddie’s front door as she and husband Nick are getting ready for the morning school run, she’s not expecting to hear what they have to tell her. Kiara is dead.

When Natasha meets Daniel, she knows her life is made. Rich, handsome and charming, Daniel will make the perfect husband. Even if she won’t make the perfect wife…She is thrilled when Daniel suggests an all-expenses paid cruise for Natasha, her friends, Barbara, Tracy Ann and Michelle, and their husbands. What better way to show everyone that Natasha has finally made it? But as the ship sets sail, she learns that far from being the perfect husband, Daniel has terrible secrets that are about to be revealed.

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…

Saffy is waiting to go into an important meeting when she receives a missed call and then a text message from her best friend, Leona: Please help...come now. Of course, she races to her friend’s house. But when she arrives, she notices something strange. This message was deleted. Leona answers the door, and insists everything's fine. She doesn't know anything about the message. Six hours later, Saffy gets a knock on the door. It's the police. They’ve found a body. And Saffy was the last one to see them alive.

When I first meet Sophie, she seems like any normal loving mother, trying desperately to help her teenage daughter. That’s where I come in. The perfect tutor to get Katie’s life back on track. I connect instantly with Katie, and Sophie’s thoughtful husband Scott. But Sophie’s dark eyes are full of jealousy when I talk to Scott or share a smile with Katie. I know I’m helping her daughter, whatever she thinks.

Her daughter died. Did she take mine? A year ago, my best friend Rachel’s daughter died. Ever since then I have held my own beautiful little girl tighter. I watch Luna shriek with laughter as she tips her toys all over the floor and I look anxiously at Rachel, sipping her tea. But Rachel reassures me that being near Luna helps fill the gaping hole of her grief, just a little. So when Luna is snatched from her bed in the middle of the night, it is Rachel who holds me tightly. She looks at the blue and white police tape crisscrossing my little girl’s bedroom and promises me they will find Luna.
