Matt Walker was a chancer; he’d spent his entire profession chasing the next job. His personal life took on a similar mantra. Life was slowly drifting him by. Until one evening, in a hotel bar, following a fortuitous meeting with the quiet and unassuming Julia. She knew of an opportunity that would be the perfect fit for Matt; one he simply couldn’t let go. Not only did the subsequent interview provide him his with dream job; it would also be where he met the love of his life. Matt and Amelia spent each day working hand-in-hand, and every evening in premarital bliss.

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 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.

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.

My mother is obsessed with every detail of my wedding–controlling my dress, my ring, my happiness. But when the day finally comes, will she really let me go?

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.

It’s midnight in the hospital when Jude’s phone rings, interrupting her precious 15-minute break. When she sees it’s her 70-year-old mother, Margaret, she braces herself for the usual complaints. But her blood runs cold at four words that will change everything...‘something terrible has happened.’ Margaret has been accused of an unspeakable crime committed 20 years ago. She insists she’s not guilty, and begs Jude to help her prove it. But as Jude is drawn into the dark secrets of her family’s past, she starts to question whether her mother is really as innocent as she claims to be.

‘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 partner José and I have poured everything into opening this rustic farmhouse retreat nestled high in the Spanish mountains. Finally we’re ready to welcome our first guests. But a cold chill comes over me when I recognize Saskia. She’s part of my old life, the one I made sure to leave behind, and that José knows nothing about. Saskia knows everything about me—even the terrible secret I’ve carried for so long. She’s exposed me once before. Is she here to do it again?

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.

Mark and I pride ourselves on giving visitors to our hotel, high on the rugged Maine cliffs with views of the ocean, a vacation they won’t forget. But the Rowes are strangely overfamiliar when they arrive with their teenage daughter. The wife puts a hand on Mark’s forearm, and her husband meets my eyes with a knowing look as I hold my little son tight. They gush that they loved their previous stay here, but I’m certain I’ve never seen them before.

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’ve lived on this quiet street for years, in the same house I once shared with my husband and our beloved daughter, Chloe. Now they’re both gone and my home, that used to be filled with laughter, is too quiet, too still. When a little boy I don’t recognize knocks at my door, without a parent in sight, I’m shocked. He trembles with nerves, and I tell him I can help find his mother. But I’m not prepared for what he says next. I’m left frozen, heart pounding in my chest.

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?

When I begin to receive threatening messages, one thing becomes clear: Cassandra wants me out of her son’s life, and she will do anything to get what she wants. Including destroying me. But that’s okay. No matter what she does, I’m confident that Miles and I will be forever. Because I know Cassandra’s darkest secret. The one she’ll do absolutely anything to keep. I have a plan, while she has no idea who she’s dealing with. And by the time my darling mother-in-law realizes, it will be far too late for her to run…
