When you return from a work trip to find your husband dead in the pond, it’s best not to call him a liar and a cheat in front of the cops. Especially when you’ve spent the last few years telling anyone who’ll listen that you sometimes fantasize about killing him. It makes you look kind of, well, guilty.

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.

The letterbox clatters and sitting on the mat is a piece of paper, in black and white, with everything needed to blow Anna’s perfect life apart. A baby scan photo.

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.

It feels like all the air has been knocked out of me. My best friend is dead, killed at her own daughter’s birthday party. All I want to do is run into my husband’s loving arms. But he’s in handcuffs, covered in her blood. His voice quivers, almost sobbing as officers put him in the police car. ‘You don’t think I did this, do you? I was trying to save her.’ At first, I’m sure he couldn’t have done it. The man I love wouldn’t hurt anyone. But as I try to prove that he didn’t murder Lucy, secrets begin unravelling…

I don’t want the perfect marriage. I want revenge… If you had met me a year ago, you wouldn’t have noticed me. A beautiful woman, but a struggling nobody in a tiny apartment, invisible… Meeting Paul changed that.

Other women look at me in envy. They see a couple completely in love.

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.

Ethan gently squeezes my hand as he slides the golden ring onto my finger. But I know we aren’t worthy of happiness. As I look down at my wedding ring, in a blistering flash, I suddenly remember another piece of that pitch-black, rainy night… but I try to focus on Ethan’s gorgeous blue eyes. I know exactly what he’s thinking. We can never tell. All our family, friends and loved ones smile as they watch Ethan and I promise to be together until death us do part. But only we know what that really means…Because we have already killed someone.

It’s important to know everything that’s happening on West Street.

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.

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?
