Two years ago, my whole world was ripped apart when my husband and best friend were killed in a car accident in Norfolk. Since then, I've struggled to come to terms with my overwhelming grief and to understand why they were together in Charlie’s car that fateful night. Following a friend’s advice, I sign up to a reputable dating site, IntoYou. She tells me it’s the perfect way to meet someone, and when I quickly get a match, I believe she is right. I am surprised how easy this is. But it seems I have a lot to learn.

Neighbors Gwen, Aimee, and Lisa share more than playdates and coffee mornings on their tranquil street in East Bethesda. They confide their deepest secrets, navigate the challenges of motherhood together, and provide a support system that seems unbreakable. But when Gwen's husband is found murdered after one of their weekly Friday night dinners, the peaceful quiet of their cul-de-sac shatters. The seemingly idyllic world of the three close-knit mom friends becomes a web of deception, betrayal, and revenge.

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 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…

When Natasha meets Daniel, she knows her life is made. Rich, handsome and charming, Daniel will make the perfect husband. Even if she won’t make the perfect wife…She is thrilled when Daniel suggests an all-expenses paid cruise for Natasha, her friends, Barbara, Tracy Ann and Michelle, and their husbands. What better way to show everyone that Natasha has finally made it? But as the ship sets sail, she learns that far from being the perfect husband, Daniel has terrible secrets that are about to be revealed.

When I first meet Sophie, she seems like any normal loving mother, trying desperately to help her teenage daughter. That’s where I come in. The perfect tutor to get Katie’s life back on track. I connect instantly with Katie, and Sophie’s thoughtful husband Scott. But Sophie’s dark eyes are full of jealousy when I talk to Scott or share a smile with Katie. I know I’m helping her daughter, whatever she thinks.

I loved the anonymity, flexibility and solitude that working the night shift at Storage Queen gave me. The unsociable hours paid well, helping me fund my university degree and giving me a quiet place to study while the world slept peacefully in their warm, cozy beds. It was the perfect job for me. But that Friday night proved to be more than I bargained for when a man walked through the door, dragging a large suitcase. My immediate instincts told me something was wrong. That’s when my ordeal began. I just had to make it through the night shift.

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 . . .

For Victoria, image is everything, and on the surface, she has it all: a big house, a successful husband, and two beautiful children. But behind the scenes, things are very different. Victoria and her husband have a dark secret, and she lives in terror of it being discovered—of her perfect façade being shattered forever. Under massive stress, but still desperately trying to keep up appearances, her family is falling apart. Victoria has to ask herself how far she's willing to go and how much she's willing to do to preserve her perfect family.

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.

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.

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.

When we move into the exclusive Westford Park housing estate, we feel safe at last. More like a country club, it has everything we might need – beautiful houses with big gardens, a pool, a boating lake, extensive grounds. It’s also got 24/7 security. Our new neighbours are lovely too. We start to make friendships that feel like they could last a lifetime. It feels like nothing could possibly go wrong here. It’s like our secrets haven’t followed us here. Or that’s what we think at first…

My handsome husband Tom. You've given me everything our beautiful son and our perfect new seaside home. I want to trust you, but I know you haven't been honest about why you really wanted to move here. I haven't been honest with you either.
