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…

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.

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…

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.

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.

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?

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.

She bursts into my life like a storm, and nothing is the same again. One by one, I watch as my friends fall under her spell. Only I see that her smiles don’t reach her cold, furious eyes. And when I’m accused of things I didn’t do, when my home is vandalized, I know she’s behind it. But she only lets her mask slip when no one is looking, so if I say anything, I’ll look crazy. So when the baby shower comes around, I’m sitting on a velvet sofa in a posh hotel room, surrounded by balloons. But that afternoon, I finally learn the unbelievable truth. There is no baby....

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.

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?

I blink awake to the sound of whispering, and look around. Automatically, I do a count. And then I am upright, my heart racing. I count again. “Girls,” I say, trying to sound calm. “Did you see Evie?” It was meant to be a celebration. A team sleepover in the school gymnasium: movies, pizza, hot chocolate. I walk among the girls, checking they’re ok. They collect in groups and giggle, play truth or dare.

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.

My wedding was the perfect whirlwind of a day. The happiest I’d ever been. That was until I discovered my beloved husband, Ryan, tucked away in a compromising summer house clinch with Liza, his best friend’s wife. Reeling with this ultimate betrayal, my world in freefall, with nowhere to turn, I flee my own wedding unable to face anyone, not even my family. I just want to escape this nightmare. With our flight, to our luxury honeymoon leaving in a matter of hours, could ten blissful days of Cretan Island life, minus my cheating husband help me figure out my future?

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.
