I open the creaking oak front door of my beautiful country house to see a stranger on my doorstep. The woman is stunning with glossy red hair and flawless make up. "Can I help you?" I ask. That was my first mistake. Alexis tells me she is a distant relative and shows me a DNA match on her phone. She has no family and would love to get to know us. My husband Hugh invites her in to join our dinner party. As we drink wine, she opens up about her sad childhood. Her amber eyes are mesmerizing, and I can see my husband is being drawn in by her story. Then she asks for our help.

Since Alice’s fiancé walked out on her, she never thought she’d meet "The One". But all that changes when she meets Dominic. Handsome, charming, and kind, Alice can’t believe her luck when he proposes a few months later and moves into her West London home. Three years on, Alice’s catering business is thriving and she is married to a man she adores. So when she sees that little blue line, it should be the happiest moment of her life: they’re going to have a baby. But then the police knock on her door and Alice’s whole world is turned upside down...Dominic is dead.

One honeymoon resort. Two couples. Everyone has something to hide. On the surface their lives seem perfect. Beauty, money, love. They have it all. Tansy and Daniel. Nikki and Arne. Two newlywed couples enjoying their enviable honeymoons at the same luxurious resort. But behind the filtered photos and fake smiles is the truth.

Behind closed doors I try to relax, to unwind in the huge clawfoot bath and forget about my complicated past. It’s hard being the new couple on the street when you’ve got secrets. Because the truth is, my charming husband isn’t really my husband. And I’m not Stephanie Hamlin....

Everyone thinks I’m living the perfect life. I have my dream job, a stunning apartment, and glamourous friends – who know nothing about my dark past. So I’m shocked when I run into Anna, who I haven’t seen in eighteen years. Everything about her reminds me of the life I’ve left behind. But as her eyes fill with tears and she tells me she’s lost her job and can’t pay her rent, I reluctantly offer her my spare room.

Marianne has a life others dream of. A beautiful townhouse on the best street in the neighbourhood. Three bright children who are her pride and joy. Sometimes her past still hurts: losing her mother early, growing up in foster care. But her husband, Simon, is always there. A successful surgeon, he’s the envy of every woman they’ve ever met. Flowers, gifts, trips to France: nothing is too good for his family. Then Simon says another woman’s name. The way he lingers on it, Caroline, gives Marianne a shudder of suspicion, but she knows it’s nothing - she can’t entertain this flash of paranoia.

When I pick my beloved daughter Poppy up from school one afternoon, my mind races when I see the little girl holding Poppy’s hand. With the same heart-shaped face, long brown hair, and dark eyes, the two girls look identical. In fact, they look like sisters. Is the secret I’ve been holding on to for so long about to be revealed? 

Six-year-old Lola Jade Harper is taken from her bedroom. Her mother is distraught. She is convinced her estranged husband, Gavin Harper, has abducted their daughter. Detective Rachel Prince is leading the investigation but is soon out of her depth as she searches for the most high-profile missing child in the country. To uncover the truth about Lola’s disappearance, Rachel must untangle the Harper family’s complicated web of secrets and lies.

With its peeling wallpaper and overgrown garden, I know our new home isn’t perfect. But my husband, Ben, promises it’s the fresh start we need. I remind myself that he’s an amazing father to our two children and that we have years of happy marriage behind us. He’s been distant for months, but I’m desperate to believe the move will bring us back together.

My darling little boy Albie adores playing at our new neighbours’ house. And after the terrible year we’ve had, I feel so lucky that we can start over in this perfect place, with new friends who treat Albie like the son they never had. He can’t stop talking about the tree house they’re building him, and the cookies they bake together. But as time passes, something starts to feel wrong. Why don’t they ever open the front door more than a crack? They told me they had no children so who does the small pink tricycle I saw in their hall belong to?

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 I reach my husband, we kiss against the perfect backdrop of the shimmering turquoise sea. The congregation claps, and I turn to smile at them. Then my smile freezes. I see him. Sitting there among my loved ones. An uninvited guest who knows the truth about me and the terrible thing that happened 10 years ago. The man who won’t ever let me be happy. And as he steps forward, asking for everyone’s attention, my legs buckle. I know he wants to destroy my perfect new life.

You think you can trust the ones you love most. But what if one secret could make you question everything? Every day, a woman like Louise passes you in the street: elegant, confident, determined. But underneath, she’s struggling. She doesn’t know her sister, Alice, has been scared of leaving the house since their mother died. She doesn’t know when Alice babysits her little boy, Archie, he sometimes sees things he shouldn’t. She doesn’t know Archie has a secret. A secret that could send cracks through the heart of Louise’s carefully constructed life....

Hattie travels on the 18.53 train home every night. She sits in the same seat, in the same carriage, and sees the same people. The unwritten rule is you don’t talk to your fellow passengers, but Hattie has been watching them all for months now to distract herself from her own troubles.

Kirstie Rawlings is jolted awake by a child crying. Racing upstairs to check on her newborn, she is plunged into every parents’ worst nightmare. She hears an unknown voice in the baby monitor, saying: "Let’s take the child - and go." Is someone trying to steal her little girl? In the bedroom, her daughter is safe asleep in her cot.
