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…

Ava only left her daughter in the pushchair for five minutes. The buckle was fastened, and she was sure it was safe. But when she came downstairs, the door was open and Abi was gone - she walked down the road, past the Lovegoods' house, and was never seen again. A year later, the Lovegoods throw a housewarming party, showing off the results of their renovation. Ava doesn’t want to go. She can’t bear to look down that end of the road, to see the place where Abi vanished, and she doesn’t want to spend time with people who don’t share her grief.

Alex and I haven’t been dating for very long when I go to his place for the first time. Feeling self-conscious as I notice a thread coming loose on my dress, he pours me a glass of wine and I take in the pristine room and expensive furnishings. Everything here is perfect, too perfect. Where are the personal touches, the souvenirs from his life? Where are the photos of his friends and family? ‘You can trust me,’ Alex says as he hands me the wine, and my heart beats wildly in my chest. I really want this to work, especially after the disaster of my last relationship.

I am on my way home, thinking only of the quiet, happy evening to come, when I see something completely impossible, and my heart stops dead. I would recognise those gorgeous pale blue eyes anywhere. It’s him. The high-school boyfriend I adored… Until the day he vanished without a trace. I run towards him, my pulse racing. He turns, politely, a puzzled look on that familiar face. ‘I’m sorry,’ he says. ‘Do I know you?’ I need answers. I’m certain he’s lying. I just have to prove it.

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 stare at the messages between my husband Rob and another woman, their plans to run away together bringing tears to my eyes as I stand, trembling, in our luxurious apartment. I thought I had the perfect marriage. As our three beautiful children sleep soundly in the next room, I think about our family holidays, our romantic date nights, and the day Rob proposed to me. In the last few months, I haven’t complained about his late-night meetings or got jealous about his weekends away. I trusted my husband. But now I’m questioning everything.

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’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?

My mother is obsessed with every detail of my wedding–controlling my dress, my ring, my happiness. But when the day finally comes, will she really let me go?

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.

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…

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.

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.

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?

I was so nervous about someone new joining our house share. After everything that happened with my parents, my friends are like my family. Our imperfect, but well-loved house is the only place where I can be myself. But when Poppy knocks on our door, blonde hair, wide eyes, and a friendly smile, we all agree she’s a perfect fit. I just wish I could shake the feeling that I’ve seen her before…
