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.

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.

I used to enjoy my job. I was good at it and felt fulfilled. I also used to enjoy spending time with the people I worked with. They say you spend more time with your work colleagues than you do with your family members, but that was fine by me because I made two very good friends at the office. I also allowed myself to get a little too close to my boss, but I soon realized that was a mistake. Unfortunately, it was too late by then, and as my personal and professional lives quickly blurred into one, that was when everything changed.

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?

I thought my first husband died ten years ago. But now he’s back... Opening the front door, I’m stunned to see a familiar face. I never thought I’d see Freddie’s deep brown eyes and crooked smile again. But how is this possible when he died ten years ago…? It took years to move on, but finally my life is almost perfect.

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…

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.

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.

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 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.

After the year Aidan and I have had, we needed some respite. My husband is overworked, whilst I'm anxious about the past, so renting a night at this converted barn house in the countryside seems like the perfect place for the pair of us to relax and unwind. It might be situated at the bottom of a large garden, but it's private enough that we don't have to mingle with the homeowners who live nearby. Or at least that's what I thought . . .

After my first husband died, I thought my heart was completely broken, and that I’d never feel happy again. Until I met Theo. He’s a doctor. A man who seems good and caring and kind. Soon after we start dating, he says he wants to marry me. And even though his grown-up children are less sure about me, to everyone else it’s the second chance for love and happiness I deserve. But the truth is maybe his children are right to be suspicious. Because I know something about Theo. That he was there in the operating theatre the day my first husband died. And I think it was his fault.

After meeting Jamie’s smiling blue eyes across a crowded bar, I tell myself, that after my recent divorce, this is the bit of fun that I need. It is the biggest mistake I’ve ever made. Because when I return to his flat the next day, excited to see him again, I am horrified to discover he has been murdered. I know I should tell the police, but I can’t be the person to call them. With my past they will just assume the worst…
