The moment I first gazed into Alex's soulful gray eyes, I knew I'd met the man I wanted to spend my life with. And I was right. When my beloved sister vanished, Alex put up posters and wiped away my tears after bad dream—she put me back together. But when police pull a crumpled photo from my dead sister's pocket, and I see my husband's familiar face smiling back at me, my perfect world shatters.

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.

Last night, we celebrated our anniversary. Over candlelight, we talked about the children, our work, and I was so happy, and felt so loved. But the next morning, when I check my phone, there is a message. From a friend. And a string of photos appear of my husband, Will, with another woman: walking along the street holding hands. Going into fancy hotels. Standing at a window, his arms around her, her head on his shoulder…

Ethan gently squeezes my hand as he slides the golden ring onto my finger. But I know we aren’t worthy of happiness. As I look down at my wedding ring, in a blistering flash, I suddenly remember another piece of that pitch-black, rainy night… but I try to focus on Ethan’s gorgeous blue eyes. I know exactly what he’s thinking. We can never tell. All our family, friends and loved ones smile as they watch Ethan and I promise to be together until death us do part. But only we know what that really means…Because we have already killed someone.

Thirty years ago, Georgia Smith was my best friend. Then one terrible day, everything changed. I’ll never forget her beautiful face, twisted with hate, the last time I saw her. But I never thought I’d have to see it again. Georgia is back. She’s my daughter’s new favourite teacher. And now my baby girl is gone...

It feels like all the air has been knocked out of me. My best friend is dead, killed at her own daughter’s birthday party. All I want to do is run into my husband’s loving arms. But he’s in handcuffs, covered in her blood. His voice quivers, almost sobbing as officers put him in the police car. ‘You don’t think I did this, do you? I was trying to save her.’ At first, I’m sure he couldn’t have done it. The man I love wouldn’t hurt anyone. But as I try to prove that he didn’t murder Lucy, secrets begin unravelling…

My hand trembles as I stare at the anonymous text. On this sunny Saturday morning, our twin ten-year-old boys were playing in the park just down our tree-lined street. But only one of them has come home… and it’s all my husband’s fault. I race to Leo’s study and demand answers. As his face turns white, I know: one of his affairs has turned deadly. I always smell the unfamiliar perfume on his shirt. I try to pretend we are a happy family, for the sake of the children… but now, my child is in terrible danger.

When I wake up, I know three things. My name is Emma. Someone tried to kill me. And I can't remember who. When I blink, my eyelashes brush against scratchy cloth. My fingers twitch, numb and distant. In the distance, sirens wail. I'm in the hospital. I should be safe here, but I know I'm not. The last thing I remember is running, seeing an arm raised to strike Why would anyone want to kill me?

Ever since my daughter Isa was born, I’ve been struggling. I can’t remember anything, and my brain is in a fog. So when my husband Ned suggests we hire a night nanny, I leap at the chance. As soon as she walks into our home, I feel a wave of relief. I smile at her and notice her eyes are the color of amethysts. A memory flashes across my brain, but before I can grasp it, it’s gone. But something isn’t right. Ned is acting strangely and every time I ask him why, he tells me I’m being paranoid.

I know Benjamin’s new business is in trouble, that he desperately needs your money. I saw the way Gwyn looked at him at your wedding reception, finding any excuse to be close, to laugh too loudly at his jokes. After all, she always wanted your perfect life. But don’t worry, Madeline. I won’t let it end like this. I can see everything from my place in the shadows between the trees. With their house lit up, they are on display. I’ll bide my time and worm my way into their home, their lives. They will never know the truth about who I am.

When Paige Nichols meets her husband’s glamorous new colleague at a faculty mixer, she instantly knows they’re having an affair. It’s the way he looks at her, like she’s the only woman in the world. Aaron used to look at her like that, too. And with her beautiful, knowing smile, Cara Morton seems to enjoy flaunting their romance right under her nose.

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.

Tom, my husband, is always watching, controlling my every move. He chooses my clothes, my hairstyle, even instructing what and how much I’m allowed to eat – just ten measly mouthfuls. I’ve become isolated from those I love, forbidden to work and stuck at home to fulfil his every whim. My identity along with my life is long gone. I am slowly suffocating but I know Tom will never, ever let me leave alive. A chance encounter with Savannah changes everything. Tom couldn’t tear his eyes away from her. Could she be my saviour?

A bright and welcoming haven, the playgroup sits at the heart of the town, tucked away inside a red-brick building. The Nest should have been the safest place for my rosy-cheeked, pink-obsessed daughter, Florence. Run by mothers like me, I trusted my newfound friends–Alice, Beth and Georgie–to take care of my child. But now my choice has left Florence fighting for her life.

When I accepted a job working as a nanny for David and Julie and their young children, I was excited to be making my own way in the world. I bonded with baby Chloe instantly and would have done anything for her. She had David's thick, dark hair and smiling eyes. I fell in love with her and was excited for my future. But when a terrible mistake led to Chloe disappearing, I was instantly blamed. With no evidence, I was let go and I returned home to rebuild my life. Twenty years later and I am still haunted by what happened.
