Every Monday, I meet my writing group in a warm, lively bar to drink a glass of wine or two and share our work. It’s the highlight of my week. I don’t go out much, otherwise. For the last ten years, every time I’ve relaxed, the messages have started again. The black hearts. They’re a warning to remember, as if I could ever forget. Whoever sent them wants to hurt me. They’ve lost me jobs and boyfriends. Is it any wonder I like to hide in fiction?

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…

I tell myself that Max couldn’t kill anyone. He’s a family man now, different to who he was before. Even so, I should go to the police right away. But I can’t. Because if I do, I’m scared they’ll start to suspect me. How much do I really know about the girl in room 12? And if the truth comes out, how far will I go to protect my precious family?

In the wake of my darling husband’s death, I am so lucky to have my three beautiful, grown-up daughters by my side at our holiday home in Scotland. We need some time together to recover from the shock. But I also need to set some things straight about their beloved father....

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.

Two days ago, the Wilson family checked into the imposing, glass-fronted Lodge, surrounded by snow and perched perilously on the edge of a cliff looking out to a gray sea. Not everyone was looking forward to the family get-together. But mother-in-law Angela insisted the winter trip would help heal their rifts....

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.

Leah and her three best friends get changed into their pyjamas, eat pizza, and argue about what film to watch. They laugh together, until the early hours. But the next morning, Leah blinks open her eyes and sees three empty sleeping bags. The other girls are gone. Twenty years later. In her small hometown, still-haunted Leah has never been able to shake off the rumours and whispers. How could she have slept through it all? She must know what happened.

I’d heard of the Baby Caroline case, of course. When a baby is snatched from her mother’s arms, the whole country knows about it. I knew about the parents left lying by the swimming pool, the open window in the nursery. But I never dreamed it had anything to do with me. Today, my beautiful daughter turned one. We were unwrapping gifts and blowing out candles when the knock came at the door, and they took my mother away. The police say she’s not really my mother. That she stole me, 30 years ago.

Some doors are locked for a reason.... While 11-year-old Nora Davis was up in her bedroom doing homework, she had no idea her father was killing women in the basement. Until the day the police arrived at their front door. Decades later, Nora's father is spending his life behind bars, and Nora is a successful surgeon with a quiet, solitary existence. Nobody knows her father was a notorious serial killer. And she intends to keep it that way. Then Nora discovers one of her young female patients has been murdered.

Two women. An office filled with secrets. One terrible crime that can't be taken back. Dawn Schiff is strange. At least, everyone thinks so at Vixed, the nutritional supplement company where Dawn works as an accountant. She never says the right thing. She has no friends. And she is always at her desk at precisely 8:45 a.m.

Katelyn smiles around at her husband and friends, gathered to celebrate her 36th birthday in their beautiful home decorated with fairy lights. But the next day Katelyn wakes up shaken and terrified in a hospital bed. She doesn’t remember the sweet taste of birthday cake icing, or how angry her best friend was at midnight, or the terrible things her husband said. She doesn’t remember the party at all. When she asks her husband what happened the night of the party he says "nothing". But her blood runs cold at the way his voice lilts slightly. The way it always does when he is lying.

A year ago, someone broke into our home. He stood outside our bedroom, with our children asleep down the corridor, and knocked on the door. But the worst moment came later, when I found out who had nearly destroyed my family, and why. Now my husband has booked us a surprise vacation. In a beautiful cabin on the shore we will rest, talk, recover. But I can’t relax. When I drive to the store, or stroll down the beach, I am always looking over my shoulder, my heart racing. Because no matter how hard my husband tries to pretend, we both know it’s not over.

You’ve been excited about this getaway for months–at last, a chance to reconnect with your husband at a secluded island resort. But when he unexpectedly calls you from the beach, you hear the urgency in his voice. Something is very wrong. The beautiful waitress from the restaurant last night has been found lying dead in the sand. And the police want to question your husband about it. Sure, you saw him glance at her over dinner a few times, but you know he didn’t have anything to do with the poor girl’s death.

Erika has always sensed something dark and disturbed in her seemingly perfect older child. She wants to believe he's innocent, but as the evidence mounts, she can't deny the truth - Liam may have done the unthinkable.
