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.

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.

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…

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…

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.

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’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?

On the last day of school, my friends and I gather on the beach to celebrate the long summer ahead. Sipping cans of warm cider and watching campfire embers dance into the inky sky, I don’t think I’ve ever been happier. Until a scream pierces the night. The next morning, we find shy newcomer Pippa on the beach, sandflies gathering on her lifeless body…

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.

Charlie takes my breath away from the moment we meet, when he is dropping his adorable little girls off at the school gates at the same time as I’m waving goodbye to my son. Being a single mother has been hard. So when his gorgeous green-blue eyes hold mine and his lips curve into a smile I wonder if this is my chance to find happiness and escape the secrets in my past.

They say I’m lucky to be alive. But the only thing I can remember are the faces of my husband and baby. The husband and baby they insist don’t exist … I can hear a door slamming, and the low hum of distant traffic. I struggle to open my eyes, and the panic sets in. I have no memory of who I am, why I’m here, where all this pain is coming from …

Some secrets refuse to stay buried... Abandoned by her mother, Lucy Mitchell grew up in foster care, where she found solace in her best friends, Amber and Josh. In a strict foster home, Lucy and Amber made a pact – friends for life – often escaping to the woods to hide from their overbearing carer, Linda. Then, one day, only one of them comes back. Amber was gone, leaving behind only a note: I’ve run away. Fifteen years later, Lucy is planning her dream wedding to Josh – until a body is discovered.

Emily has the perfect life. The perfect husband. The perfect daughter. But she also has the perfect secret. One that could destroy everything she holds dear... one that could ruin her.

Saffy is waiting to go into an important meeting when she receives a missed call and then a text message from her best friend, Leona: Please help...come now. Of course, she races to her friend’s house. But when she arrives, she notices something strange. This message was deleted. Leona answers the door, and insists everything's fine. She doesn't know anything about the message. Six hours later, Saffy gets a knock on the door. It's the police. They’ve found a body. And Saffy was the last one to see them alive.

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.

When city girl Shona moves with her partner Mikey and their baby to an idyllic cottage in rural Scotland, she believes that all that lies ahead for her family is happiness. But with Mikey working long hours away from home, the frightening isolation of the Scottish countryside begins to get to Shona. She feels lonely and trapped. That is, until she is rescued by a new friendship with the enchanting Valentina. Valentina enters Shona’s life like a whirlwind, bringing excitement and spontaneity to replace boredom and fear.

I look at our neighbours gathered in the garden for our annual summer barbeque, sipping chilled wine and smiling at my two daughters sprawled on the grass. I go inside to help refill glasses and then I hear it. A shrill scream that stops me in my tracks. I race outdoors to silence, a sea of bewildered faces. My first thought is for my girls, but they are there unhurt. With relief, we push the chilling sound to the back of our minds, returning to our drinks and conversations like it never happened.

When Emma meets Matthew, a kind, handsome widower, he seems to be just what she needs. Yet as their relationship moves fast, Emma’s friends worry she might be exploited. She’s a rich woman after all. Emma doesn’t care Matthew has no money. But as the memory of his perfect first wife hangs over them, Emma does have one tiny doubt. If Matthew’s wife hadn’t died, he wouldn’t be with her. And Emma wonders if she’s second best. Can she ever fill the dead woman’s shoes?

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…

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…

When Tuppence was born, I thought I was complete. Even when my marriage to Leon began to falter, at least I had my baby girl to look after. Adults have problems all the time, but children have a way of making them seem so insignificant. But then Tuppence goes missing and I realize how my life has been teetering on the brink for so long. Now it's just me and my husband again, the two of us and all our problems, and we're forced to work together as a team to get our beloved daughter back.
