‘My name is Darcy, I’m your nurse and I’m here to help you.’ I repeat the words I’ve said so many times. Except this time, I don’t mean it… If you saw me walking down the street, you’d think I was pretty ordinary–I wear the typical crisp, white nursing uniform, my hands are scrubbed clean and you’d have no reason to believe I was anything other than a good citizen. A good nurse. But looks can be deceiving. You shouldn’t trust me–because I don’t even know if I can trust myself.

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.

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.

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 . . .

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?

My husband is a doctor. He’s smart and charming, and everybody trusts him. Except me. On the surface, it looks like I have it all–the perfect marriage, the perfect husband, the perfect life. But it’s far from the truth. Doctor Drew Devlin is not the respectable figure he makes out to be. The reason we moved to this beautiful, old property with a gorgeous view of the sea was because we needed to put our past behind us. It should’ve been a fresh start for us both.

When Ellie tells me she has a new boyfriend, I am absolutely thrilled and can’t wait to meet him. She finally seems so happy and in love. But there’s a catch. Ellie has never met him in person. In fact, he doesn’t even live in the same country. Our home is in England, but Daryl is in Los Angeles.

Becky and Jamie are an ordinary hard-working couple trapped in the daily grind, dreaming of an easier life. On one of their rare vacations, they meet Phil and Mel, a wealthy couple who seem to have it all—they're fun, well-traveled, and very generous with their money. But they are also very, very dangerous. Phil and Mel are not who they say they are, and this is no random vacation friendship.

Amy is a loving wife and mother, to her husband Nick, and her two children, Michael and Bella. It's that dedication to her family that causes her to seek help for her teenage son when it becomes apparent that he is going to fail his end of school exams.

Heather is a single mom who has always done what's best for her daughter, Chloe. From birth up to the age of seventeen, Chloe has never been any trouble, until one night when she calls her mother with some shocking news. There's been an accident. And now there's a dead body. As always, Heather puts her daughter's safety before all else, but this is one time when she goes too far. Instead of calling the emergency services, Heather hides the body, saving her child from police interviews and public outcry.

Imogen should be enjoying her life–she is happily married with a high-powered career that could see her rise to the very highest levels of management. But that’s never going to happen because Imogen’s boss, Michael, has discovered she has a secret, something she has hidden from everyone, even her devoted husband. If the secret is ever revealed, her life will be destroyed, which means Imogen is completely and utterly in Michael’s power, and he loves it.

I planned the perfect vacation. But now my son is missing. Everyone believes my husband Donovan and I have it all—a loving marriage, two adorable children and the dream house. But beneath the surface of our enviable American lifestyle lies a secret that binds us tighter than our vows.

I sit sipping champagne in the warm water, bubbles frothing around me as I admire the breathtaking view of gorgeous blue skies and mountains. I can’t believe I’m here, at this stunning holiday home. It’s to die for....

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…

I could tell when my son started hiding things from me. He used to walk to school with a mischievous grin on his beautiful face. Now he avoids eye contact and keeps his head down. Since I discovered he’s being bullied by a classmate, I’ve spent every day worrying, my stomach churning with anxiety from the moment he leaves the house to the second he walks back through the door. Everyone keeps telling me I’m overreacting, but I won’t risk my child’s safety. My husband and I try to talk to the other boy’s parents, but it only makes things worse. Then our precious child is hurt. Enough is enough.

When three women head to Portugal for a long weekend in the sun, the goal is to celebrate an upcoming wedding. Jane is getting married, and Angela and Maya want to give her a good time before she does. But the carefree getaway soon goes awry, and by the time the friends board their flight home, they are all carrying a terrible secret. It's one that could ruin each of their lives, which is why they make their pact—they agree to tell no one else what happened while they were away.

But then she realizes her ex-boyfriends are turning up dead. At first, the deaths seem accidental, but soon a sinister pattern emerges. All of Adele’s former partners are being killed off—in the order she dated them. As the body count grows, Adele has to figure out who is doing this and why. Otherwise, it’s only a matter of time until the killer gets to Tom.

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.
