Lisa remembers the first part of the night: an evening in the pub with her best friend. Then nothing. She wakes up, days later. She's in hospital. Her best friend is dead. Lisa holes up in a remote country cottage, plagued by guilt and flashbacks: how did their assailant know them? Why were they attacked? And what really happened that night? With only vague memories of the event, she cuts herself off from friends and family, spending her days wandering the hills with her dog, Riley.

Heather has lucked out. She has a beautiful house, a happy marriage to James Jessop, with two sons — and she’s just won the lottery. £29 million! Natalie has never quite kept up, but she’s finally in a relationship with a new boyfriend, Nick. She’s been best friends with Heather since they were bullied at school. But will her friend’s new fortune change their friendship? The Jessops’ comfortable life dissolves into chaos. Heather starts receiving anonymous, hateful messages. She begs Natalie to escape with her to Spain, but away from the spotlight in London, things go from bad to worse.

Beth wants to love her new home on a quiet suburban street. She wishes she could make friends with her beautiful neighbour Oksana. She longs for a new group of friends. Welcoming neighbours to visit. Coffee dates and dinner parties. But life here feels so closed. Then Beth runs into Oksana’s garden one day to fetch her runaway dog, and she sees something shocking that makes her wonder who her new neighbours really are. A girl in the window. A pale desperate face. A hastily scribbled sign bearing only two words.

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.

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.

My husband and I are fighting for our lives in hospital after a terrible car accident. But despite my pain, all I can think about is what our families will find behind our front door. The scarf that has been all over the news, belonging to a dead young woman with honey-coloured hair. I have to speak to the police before my husband can. I’m drifting in and out of consciousness, but when I hear my wife talking to the police, accusing me of the murder of an innocent woman, a cold fear grips me. I know I’ve got a temper.

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 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?

Marcella Middleton has always tried to live a good life, but after losing her job, her boyfriend, and her home, she's tired of playing by the rules. But she has a plan. She's going to trick her way into Carmel and Rufus's home, that sickeningly perfect couple with the amazing, renovated farmhouse they're always boasting about in those glamorous lifestyle magazines. She'll tell them she only wants to stay for a few days, even though she never intends to leave. She has no idea the house is haunted by the ghosts of the past. Or that the couple have a sinister hidden agenda of their own.

“There’s no place like home.” That’s what I tell myself as I pull another flawless meal from the oven. This perfect house on a quiet street was supposed to be my sanctuary, a place to recover. But everything changed the moment I saw that woman in the charity shop. She triggered something dark, buried deep within my memory.... 

Never question a mother’s intuition. My water isn’t supposed to break while there’s a storm raging, when my husband isn’t on the island, and as the power flickers out. Darkness covers the cabin as I cling to my belly. I never imagined it happening like this. Trained as a midwife, I know I can deliver my daughter.

Vanessa and Curtis have just moved to an idyllic house in the seaside town of Whitstable. Their life there is wonderful, until Vanessa’s ex-boyfriend Hayden shows up out of the blue. Hayden is not only brash and unpredictable with a warped sense of humour, he also seems intent on making life very difficult for Vanessa, who hasn't seen him since she was sixteen. As Hayden causes more and more disruption in their lives, Curtis begins to realise that he has some kind of bizarre hold on Vanessa.
