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…

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.

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.

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 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 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.

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…

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 just a little girl, fast asleep in my stroller, the day my mother was killed. I don’t remember anything about the sunny day that turned so dark. She’d be so happy for me now, 20 years later, with my dream job as a photographer, and I’m sure she’d love my new boyfriend, Gabriel. But all my happiness vanishes in a heartbeat when the man from our past walks toward me, his eyes on me for just a fraction too long.

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?

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 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.

I’ve fallen in love with a man called Sam. And he’s perfect, just perfect. It’s a whirlwind romance. And when our dream home falls through just before our wedding, we decide to move in with his parents. He says his mother, Evelyn, is the sweetest person. But I’m not so sure. She’s obsessively protective over Sam. She wants to know where he is all the time. She wakes us up in the morning, bustling into our room like he’s a small child, not a grown man. She doesn’t want me to be alone with him.

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.

When I first walked into Jake and Megan’s immaculate home, I felt totally at ease. Sitting in the crisp white living room, they held hands and talked lovingly about their baby girl, Fern. As the weeks passed, I began to think I’d made a mistake in taking the job. Jake was overly friendly from the start, watching my every move and always offering to drop me home, even though it was out of his way. And Megan seemed to take pleasure in telling me off in front of her husband, blaming me for things I hadn’t done.

You trust them with your child. You shouldn’t. Each Monday after school, I look after my daughter Coralie and four other kids from her class. We go to the park when it’s sunny, snuggle on the sofa reading books when it rains. Tuesdays to Fridays, the other parents take them. It’s perfect–a circle of free childcare, of fun and friendship for our children. But this morning, we all received an anonymous note. And now I’m terrified.

My husband is lying. The minute he came home with alcohol on his breath and unable to look me in the eyes I knew it. We used to be in love–the intense ‘I can’t be without you for a second’ kind. Where it hurts deep to be apart. But now, we’re the couple that keep secrets from each other. We hide the truth. He thought I wouldn’t find out. I’m a detective–it’s literally my job to uncover clues and solve mysteries. I know what he did. And now I’m sitting here, in a police interview, being asked the question ‘did you kill her?’ to which I utter one life-shattering word: ‘yes.’

Julia White is struggling: her bartending job isn’t cutting it, and her first book has sold hardly any copies. She’s broke, barely able to make ends meet while drowning in her late mother’s medical bills and reeling after a one-night stand with her ex-boyfriend, who’s now completely ghosted her. Enter Johnathan Aster, world-renowned photographer, with a proposal: he has a never-before-seen photograph of a woman falling from a train bridge, clutching what appears to be a baby. And he wants Julia to research the story.

After surviving a nightmarish childhood, Anneliese Bakker is on the mend and searching for her birth mother. But when she meets Willem, she falls madly in love and finally finds a safe place to land. Engaged and expecting her first child, she moves into the Veldkamp mansion on a stately tree-lined avenue in Amsterdam. And yet, nothing about Willem’s family is as it seems. Instead of the loving home she has longed for her entire life, she’s confronted with a cold and hostile household.

When Constance hears the knock on her door her heart misses a beat in fear. She ushers the police in, and they tell her to sit down. It’s hard to stop her legs from shaking and their words buzz in her ears as they tell her that Daniel—the husband she has always loved—has been found dead in what they believe is a tragic suicide. As Constance breaks the news to her teenage daughter Cathy her thin shoulders shake with sobs. She says that her father had everything to live for and he wouldn’t have left them behind. Constance knows this is true. Because she also knows about Maya, the other woman.
