Eliza has everything I’ve ever wanted. Three perfect children. A doting husband. A dream home. But I know a secret that could destroy it all. When Eliza Watts hires me as her assistant, I can’t believe my luck. I steady my nerves as she glances approvingly at my glittering CV. I need this job more than anything. But she must never know why. It’s funny she doesn’t recognize me, because we’ve met before. And ever since we crossed paths, I’ve wanted nothing but to be close to her and her flawless family.

When a young boy discovers the body of a woman beneath a thick sheet of ice in a South London park, Detective Erika Foster is called in to lead the murder investigation. The victim, a beautiful young socialite, appeared to have the perfect life. Yet when Erika begins to dig deeper, she starts to connect the dots between the murder and the killings of three prostitutes, all found strangled, hands bound, and dumped in water around London.

Pete never wanted another child. Before baby Erin was born, they were happy. If Natalie hadn't got pregnant, he would never have done what he did. Natalie knows things have been difficult since the surprise arrival of Erin. Life with Pete and their two other children—Emily and Zadie—has been balancing on a knife-edge. Now their home is full of guests at a party Natalie didn't want to throw—and she's about to reach breaking point. But so is her family. Because everyone has a secret that they've been hiding and when Erin suddenly disappears everyone becomes a suspect.

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.

Caroline twitches aside her curtains to see the new family moving in. A mother – beautifully dressed in expensive clothes – and two young children. Where is her husband, she wonders? And why are they moving in to the smallest house on the street? They really don’t seem the type. But Caroline believes it’s important to be welcoming. It’s important to know everything that’s happening on West Street.

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.

Anne is barely keeping it together. A frazzled ghostwriter and aspiring novelist, she juggles nine-year-old twins and a listless marriage from an overcrowded Manhattan apartment, spreading herself thinner each day. Just as Anne is about to give up on her dreams, she lands her biggest client yet: Melody Wells. Melody paints a picture of serenity and empowerment in the lavender haze of her visualization workshops—however, the one thing she can’t manifest are the pages her publisher is demanding for her new motivational book. Enter Anne.

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 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.

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…

A group of strangers arrive on a beautiful but remote island, ready for the challenge of a lifetime: to live there for one year, without contact with the outside world. But 12 months later, on the day when the boat is due to return for them, no one arrives. Eight people stepped foot on the island. How many will make it off alive?

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.

Alison is happily married to Graham, or at least she is until she discovers that he has been cheating on her. Her husband has broken the vows that he made on their wedding day. How could he do it? It takes Alison a while to figure it out, but at least she has time on her side. Only that is where she is wrong. A devastating diagnosis means the clock is ticking faster now, and the betrayed wife must act fast if she wants revenge on her cheating partner. Alison does just that, implementing a dangerous and deadly plan, and it's one that will have far-reaching consequences.

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 . . .
