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.

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.’

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…

I thought handsome, charming Blake would be the perfect fit for my quiet and sweet-natured friend Melanie. Widowed far too young, she deserved a second chance at love. So, when he proposed so soon after I set them up on a date, I convinced myself that the timing was just right. But I should have stopped it. I tried to ignore Blake’s controlling behavior. It started small; telling her not to have a glass of champagne to celebrate their engagement, putting cameras up around her house for “safety”. But Mel seemed so happy and in love, I couldn’t bring myself to share my creeping doubts.

I open the front door and there’s Amy, smiling sweetly and ready to help. She’s been a lifesaver since Jon and I moved here–from walking the dog to picking up my little son Teddy from nursery last minute. I’m so lucky we met in the playground the first day we arrived. Amy is more than just a good friend. My only friend, really. Whenever Amy and Jon exchange glances I’m sure it seems like they’ve met before, even though Jon swears they haven’t. But then again Jon recognises lots of people from his childhood round here without truly knowing them.

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…

Everything my husband and I have always dreamt of has finally come true. Our new home with its open-plan kitchen and marble countertops couldn’t be further from the small, damp flat where we lived only months ago. I’d hoped this would be our fresh start, an escape from my past, but the handwritten note that arrived on our doorstep makes my blood run cold – you don’t deserve this life.

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.

Anne gets exactly the welcome to the neighborhood she expects: a basket of homemade cupcakes delivered by the woman next door and her best friend. One wears a curious smile while the other studies her every move. When Talia and Tabitha leave, Anne throws the treats in the trash. She knows what to expect from the new neighbors. Talia with her perfect husband and pale-peach sweater sets, and Tabitha who reigns as queen in the close-knit community. That’s why she chose this house.

Meet the young widows. Together, they’ve shared their grief and emotional healing in the wake of losing their husbands. But whilst these meetings are the only places, they feel they can open up, all is not as it seems. Each woman is hiding something, but one is not who she says she is. In fact, she’s never even been married.

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?

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…

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?

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.
