Emma is so happy to have moved from the city to her husband’s small hometown. James was strangely reluctant at first – but she convinced him their little cottage is the perfect place to settle down. The perfect place to give their six-year-old son a new life. But then a woman at the school gates asks Emma if she is really married to ‘that man’. ‘Which man?’ Emma asks. The woman replies…

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 been married to my kind, loving husband Lachlan for over twenty years. He’s my everything. We have two teenage children, a beautiful home and I feel so lucky to live this perfect life. Until my best friend says something that makes me doubt everything… She whispers it’s strange Lachlan has lived nearby to two unsolved murder cases. First, the murder of the woman in the small, Scottish village where he grew up and more recently the shocking death of a woman who lived round the corner from us. The thought makes my head spin. It’s just a coincidence, surely?

Fiona Fisher lives a quiet and contented existence. A former nurse who married Jason, the doctor of her dreams, she is now a mother to his two daughters and living in the sort of cosy village home she’d always wished for.

I take a sip of coffee as I plan my day. My surgeon husband, Cole, slept at work last night, so I had to get the kids ready on my own, again. I can’t complain, though, I’ve loved him ever since we met, long before he became a famous surgeon and the papers started calling him the pride of the hospital. Our latest family photo hangs on the kitchen wall and I remember that day so clearly. Cole screamed at me over nothing, then apologised saying he was stressed at work. My heart pounded with fear, but I plastered a smile on my face for the sake of my children.

ME: Staring down at the sweet baby in my arms, I feel panic instead of love. Because this isn’t the child I gave birth to. My husband whispers to the midwife. They all think I’m going crazy. But the tiny boy in my arms is crying again. I’m certain: he knows I’m not his mummy. And I’ll do whatever it takes to get my son back.

Claire is excited to drop off a surprise workday lunch for her fiancé, Noah. It’s their anniversary, after all. But when the receptionist tells her that no one with Noah’s name works there, Claire thinks there must be a mistake. Noah isn’t picking up her calls. Her texts go unanswered. It turns out Noah has a different life . . . one with a beautiful girlfriend, a beautiful house. Claire was never really in the picture.

Young married couple Heidi and Freddie just moved to Huntington Grove. All the neighbours see they are friendly and polite but why is one door in their house always locked? Across the street, Willow tries not to argue with her teenage daughter – even as her marriage is falling apart. And where does her husband really go each night, leaving the bed beside her cold?

My delicate newborn, Lola, is just perfect. She’s made our family complete. My wonderful husband Max has his own children. He doesn’t like to talk about his first wife – and I knew it would be hard, becoming a stepmother. But now I have a child of my own. I can forget about the past.

Lucy gets the same bus every day. She hopes to get a seat to herself, tries to avoid eye contact, and, if she’s really lucky, reads a chapter of her book. But it’s a Friday - and the bus is always crammed at the end of the week. Personal space doesn’t exist. She keeps her elbows close and clings to a pole at every juddering stop. When she gets off, something feels different. An envelope stuffed with thousands of pounds is in her bag. Is it the answer to her prayers, or the beginning of a nightmare? Because, in the end, everything has a price.

Wife: I couldn’t be prouder of my charming husband and quiet and kind son. I’ve poured everything into my little family, so I choose to ignore my husband’s late-night phone calls and wandering eye. I won’t let anything ruin my perfect life…

How well do you really know your own family? The wife: Eve is desperate for her life to be perfect. Living in a beautiful house, with gorgeous views of the countryside, is all she’s ever wanted. And she’ll do whatever it takes to hold onto her dream life. The son: Joe is a model student; he never puts a foot wrong. He knows his mother wouldn’t tolerate it. Until the night of his sixteenth birthday party, when things go horribly wrong and someone in the house is left fighting for their life. As the blue flashing lights of the police and ambulance arrive, all eyes are on the Griffiths family.

She knows everything about you… but can you trust her? I walk in to my interview with Ava Green and carefully hand over my application. It’s all made up, of course, but Ava doesn’t have to know that. There is so much worry in her blue eyes. Her phone pings with constant messages and a small stain marks her crisp shirt. Breakfast with her two little girls before heading out to this high-flying job every morning can’t be easy. Ava needs me, I think. More than anything.

This is the day my life changes forever. It started so normally. The alarm went at 7am. My husband made bacon and pancakes for me and our seven-year-old daughter, the kitchen full of chatter and laughter. He gave me a quick kiss, told me he loved me, grabbed his wallet, and rushed off to work. Just an ordinary day. Until I get the call from the school. It was Tom’s turn to pick up our daughter. He must be held up for some reason. I find Tom’s phone under our bed. Now I know there’s something seriously wrong. I scroll through his messages. A text sent late last night: I KNOW EVERYTHING.

I thought he was dead. Until I saw him staring back at me… Ten years have passed since my beloved sister was murdered, leaving behind her sweet five-year-old daughter, Lily. I’m trying my best to care for Lily and salvage what’s left of our shattered family. I promised to keep her safe after all she’s been through, and after a lot of challenges, I hope she might be starting to lead a normal life again. But then I see a face in a photo I took just yesterday that turns my blood to ice.
