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 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?

I return home to our beautiful house on a chilly winter evening expecting to find my handsome husband Richard waiting for me by the fire. We’re still so in love, and he always takes care of me. He usually comes straight back from work. But tonight, our antique clock ticks on through the dark evening, with no sign of him. Then a knock at the door shatters my perfect life. A 12-year-old-girl, Alice from the village, has been found unconscious in the field behind our house. They say she was last seen getting into Richard’s car.

Charley Willis was 13 years old when her parents were killed in their family home and she was found hiding in a cupboard upstairs. Fifteen years later, Charley is marrying Seth Chambers. It should be the happiest day of their lives, a chance for Charley to put her past behind her, but just hours after the ceremony, she is missing. No one saw her leave. No one knows where she is. One thing is for certain…Seth is about to discover he doesn’t really know the woman he just married. And his nightmare is only just beginning.

Everyone thinks I’m living the perfect life. I have my dream job, a stunning apartment, and glamourous friends – who know nothing about my dark past. So I’m shocked when I run into Anna, who I haven’t seen in eighteen years. Everything about her reminds me of the life I’ve left behind. But as her eyes fill with tears and she tells me she’s lost her job and can’t pay her rent, I reluctantly offer her my spare room.

Paige, Richard and me. We thought we’d be friends forever. But everything changed the day we took the shortcut home from school along the old railway line. I wish we’d gone the long way. I wish we hadn’t seen our classmate, pale and still in the undergrowth. And I wish we hadn’t promised to keep one, awful detail a secret just between us....

I stare at the newspaper article about a baby snatched from the back of a car 30 years ago and wonder why someone would post it through my door. Looking closer, my blood freezes. The little girl in the photo has an unusual scar - just like mine. I’ve never met anyone with one like it. Is this stolen child...me? Trembling with shock, I know I have to confront my mother. My parents got me through a horrific accident, helped me find a job I love teaching art, and even with buying my own house. But was it all built on lies?

They told us he had been missing for nearly two days, that he probably drowned. They told us a lie. Megan was 10 years old when her older brother, Zac, went missing among the cliffs, caves, and beaches that surround the small seaside town of Whitecliff. A decade later, a car crash has claimed the lives of her parents. Megan and her younger sister, Chloe, return to Whitecliff one summer for the first time since their brother's disappearance.

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.

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.

I was just a little girl, fast asleep in my stroller, the day my mother was killed. I don’t remember anything about the sunny day that turned so dark. She’d be so happy for me now, 20 years later, with my dream job as a photographer, and I’m sure she’d love my new boyfriend, Gabriel. But all my happiness vanishes in a heartbeat when the man from our past walks toward me, his eyes on me for just a fraction too long.

Then: Morning light shines into the nursery, casting shadows across the pale pink walls and wooden cot in the middle of the room. She opens the door expecting to hear the soft coo of her daughter, Sofia, stretching herself awake. But the room is silent. The cot is empty. Her little girl has vanished. Now: Twelve years have passed, but Emily will never forget the night her life changed forever, and she’s happy to have her daughter back beside her. A teenager now, Sofia started asking questions about when she was a baby.

Mia and Finn are busy turning a derelict house into their dream home when Mia unexpectedly falls pregnant. But just when they think the house is ready, Mia discovers a shocking message scored into a skirting board: I WILL SAVE THEM FROM THE ATTIC. Following the clue up into the eaves, the couple make a gruesome discovery: their home was once a real-life murder house, with the evidence still concealed within the four walls.

You’d never know what secrets the house on Hogarth Street holds - what’s happening, right this second, behind closed doors. An emerald-green front lawn. Perfectly trimmed hedging. An ivy-covered front gate and the scent of honeysuckle in the air. In the yard, two scooters lie on the grass. One blue, one pink, belonging to five-year-old twins.

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....
