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.

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.

Raine Harkins believes everything the Teaching tells her - forgiveness is freedom, there are no dead, and there is no dying. She has lived her entire life in the Haven, a small religious community buried in the hills of Northern Nevada, and it's been a good life. But when she discovers a frightened teenage girl hiding in the forest, everything changes. Raine offers to help the girl, but gunshots ring out, and the girl runs away, never to be seen again. A week later, Raine finds a letter pinned to her cabin door - God doesn't want you here. Leave the Haven now, before he runs you down.

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.

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.

When a tourist girl disappears on a vacation island - and the police investigation goes nowhere - 11-year-old local boy Billy Wheatley steps in to help. He’s a little young to play detective, and he can’t tell anyone what he’s up to. But he's kind of a child prodigy, or at least, he thinks he is. Either way, he’s got a very good reason to want the police off his beach. His style of investigation is unlike anything you’ve ever heard of before, but he gets results.

‘She’s dead, Emily. She’s dead.’ The phone falls from my hand. I feel like I’ve been punched in the stomach. This isn’t possible – my mother couldn’t have been in an accident at the cliffs. She cannot be dead. Because if she is, then it might be all my fault… This first trip back home was supposed to be a fresh start for our family. Full of cocktails on the terrace and sunny days at the beach. It was time to forget all the secrets that had torn us apart.

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.’

Tonight, she walks hand-in-hand with William beneath the lustrous Seattle sky, celebrating 22 years of marriage. But they’re not alone. A mysterious black Audi comes out of nowhere and chases William onto a bridge. He shouts, “they’re here for the card”, and falls to his death.

No matter what life throws at me, I have always been able to depend on my best friend Rachel. In nineteen years of friendship, we’ve never argued or fallen out. So, I’m wracked by guilt over my decision to keep her daughter Chloe’s pregnancy a secret. I don’t want to break Chloe’s trust but, if I don’t say anything, it could destroy my relationship with Rachel.

As much as I want to support Chloe, I don’t know how much longer l can lie to my best friend.

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.

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.
