When Alice gets a desperate message from her estranged identical twin sister Cecily, she can’t help herself. She has to say yes. Pushing down the memories of the terrible childhood that ultimately tore them apart, she arrives at her sister’s house. Cecily has left instructions: how to work the oven, what to cook for supper, what to say to her husband. She says she’ll only be gone a week. She just needs to contact a lawyer, sort her head out, and work out how to get away from her marriage safely. Alice barely knows why she’s agreed...

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…

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.

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…

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.’

What if the person lying to you is your husband, the man who claims to love you more than anything in the world? Isolated in his remote Scottish ancestral home on the pretext that you are psychologically fragile and recovering from a breakdown, this home has become a prison. As the days slip by in a haze of confusion and a cocktail of drugs administered by a loyal housekeeper, you begin to piece together the fragments of your life and stumble on a terrifying secret.

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.

Jackson and Lydia Hemsworth are pillars of the community, feted for having the perfect marriage and three wonderful children – Florence, Jessica and Ezra. But appearances can be deceptive. Because behind closed doors Jackson Hemsworth rules his family with cruelty and control. His marriage is a sham; his children for years have cowed in fear. Until the day that Jackson and Lydia throw themselves off Newport Bridge in a joint suicide pact – the final cruel blow by Jackson to control his wife and torture his adult children.

Melody gazes across the rippling lake to the trees on the shore, waiting for her fiancé Evan to arrive so their family holiday can begin. Here in this cabin in a small Canadian island town, there’s so much space for their son to play. It’s going to be perfect–just like the first time Melody visited as a child. But then, a call from Evan shatters her world.

The day I was told I’d never be able to have a child, my world came crashing down. My husband says he still loves me, but I lie awake at night, wishing we could have a family. One morning, my husband’s side of the bed is cold and empty. I hear a noise and head downstairs. In the middle of the rug in my living room is a wooden drawer. Swaddled inside, with perfect rosy cheeks and beautiful round blue eyes, a baby gazes up at me.

I gaze across the candlelit table into the eyes of the man I love. It’s our anniversary dinner, a celebration of our marriage, of how far we’ve come. But within hours our romantic date has ended in murder… When I wake in a hospital bed, blinking under the blinding white lights, I hear someone saying there has been an accident. My heart misses a beat when I recognize my husband’s voice. He says I was driving the car. He says I’ve killed someone.

It’s so kind of our neighbours to throw this party welcoming us to our new home. My husband and I finally moved to the right place. A happy, safe street where nobody knows about my mistakes. But I soon learn their smiling faces hide even deadlier secrets… As I take in the little plates of sandwiches arranged over checked tablecloths, the lavish cocktails, and children playing, I finally feel happy in my new home with Owen. I love hearing the gossip from the local families; the whispers about which wives I should avoid, and which husbands sneak out at night.

Lena just moved to Mandalay Close. She needed a new start, since her boyfriend cheated her out of the happy-ever-after she’d believed they were always going to share. But on the day Lena moves in, letters begin to arrive for all her new neighbours. Letters that promise to expose everyone’s deepest, darkest secrets. Every house has received one - except for Lena’s. Someone clearly wants to implicate her, to ruin her new life and turn everyone against her. She’s made an enemy, but who, and why?

She’s the person I want to be. Sorcha Hannon, survivor of a devastating affair. She’s found the healing and hope I desperately need to find for myself. And now that Sorcha and I are friends, I am no longer alone. Instead of days hiding away from the world, I have someone to talk to. I feel as if I finally belong. There’s just one small catch. Sorcha Hannon isn’t just a new friend to me, and she certainly isn’t a stranger. In fact, I know the ins and outs of her life, and her marriage, almost as well as she does. But if she finds out who I really am, I’ll lose everything.

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…
