Kelly is taking her twin daughters to their first day of school, ushering them into the classroom, her heart breaking to think they might not need her any more, when she turns around and sees that her newborn baby is gone. As a desperate search ensues, baby Noah is quickly found - parked in front of a different classroom. But when Kelly reaches forward to comfort him, she finds something tucked beside his blanket. A locket that belonged to her sister Freya. A locket Kelly hasn’t seen since the day Freya died.

From her downstairs apartment in suburban London, Emma has often overheard the everyday life of the seemingly perfect family upstairs - Steph, Paul and teenage daughter Freya - but has never got to know them. Until one day, she hears something that seizes her attention: Freya has vanished and the police are questioning Steph and Paul about their life. Do either of you have any enemies? Anyone who might want to harm or threaten you?

Our new home was supposed to be a chance to leave our past behind. But was moving here the worst mistake of our lives? All our friends and family were gathered, glasses raised to toast our fresh start. It should have been a night for happiness and celebration. Zac and I had worked so hard for this: our first home together, just minutes from the sea. But the dream quickly turned into a nightmare.

My best friend warned me that it was too soon to marry Edward, a widower with an adorable but troubled little boy. She said we were moving too fast. But all I could see was a kind, loving man, struggling with grief, who needed my help. Yet as storm clouds gather above our small wedding ceremony, my hopes and dreams fall apart. None of my husband’s family turns up to support us. Instead of a honeymoon, we have a quiet night in. My wedding bouquet is placed on his first wife’s grave. And then my new stepson tells me he’s sure his mother is still alive.

My darling son, Sam, is marrying his childhood sweetheart, and I couldn’t be prouder of the man he’s grown into. Walking out on his abusive father all those years ago was the best thing I ever did. And today he stands, tall and handsome, saying "I do" to my dream daughter-in-law. If I hadn’t pushed them together all those years ago, he might never have found a girl as perfect as Lauren. It’s true what they say, mother always knows best. 

Me and Will. Will and Me. A perfect match. He said he would always be there for me, but it’s been a year since he drained his coffee, walked out the front door and vanished. Did he leave me? Or did something terrible happen? I’m scared someone finally found out about what happened on the drive home that night...I lie awake at night trawling the internet for rental properties, desperate for an escape. Until I see my husband’s gorgeous face smiling back at me from a photograph on the fireplace in someone else’s home, and something inside of me snaps....

From behind the curtains, Sarah spotted the man coming out of the house, followed by the woman. It would be strange seeing people in the property. She wondered how much it would change their lives. For now, she would bide her time and hopefully get to know them better. She needed to gain their trust.

Ava only left her daughter in the pushchair for five minutes. The buckle was fastened, and she was sure it was safe. But when she came downstairs, the door was open and Abi was gone - she walked down the road, past the Lovegoods' house, and was never seen again. A year later, the Lovegoods throw a housewarming party, showing off the results of their renovation. Ava doesn’t want to go. She can’t bear to look down that end of the road, to see the place where Abi vanished, and she doesn’t want to spend time with people who don’t share her grief. 

Carly had thought they’d always live there. The beautiful Cornish cliffside house they’d taken on as a wreck, that Mark had obsessively redesigned and renovated - a project that had made him famous. It was where they’d raised their children, where they’d sat cozily on the sofa, watching storms raging over the sea below. It was where they’d promised to keep each other’s secrets. Until now. Because Mark has fallen in love. With someone he definitely shouldn’t have. Someone who isn’t Carly. And suddenly their family home doesn’t feel like so much of a safe haven. 

When Beth was 10 years old, her beautiful, wild mother, Alice, disappeared. Beth’s life since hasn’t always been easy, but now she’s settled, with a successful career, a loving family and a beautiful home. Then one day, there’s a knock at the door. Alice has returned. Desperate to rebuild their relationship, Beth invites her mother to move in. At first, everything is wonderful. But then Beth’s friends start to drift away, strange things happen at home and rumours about Beth begin to circle. Someone is out to destroy Beth’s newfound happiness. But who?

Seven-year-old Beatrice has gone missing. Her mother Claire’s whole world has been turned upside down in just one moment, and she can’t stop shaking. She’s desperate to find her precious daughter, but nothing about the day she disappeared makes sense.

You're not who you say you are. Neither is she. She thinks she knows me. She believes my marriage is falling apart at the seams, that my husband can barely look me in the eyes. She thinks I’m desperate for a baby, that my longing for a family keeps me up at night. As much as I hate to admit it, all of this is true. She thinks I listen to her advice, that I care about her opinion. That couldn’t be further from the truth. Because she has no idea who I am. She has no clue that I know everything. I know her secret. I know that she did the unforgivable. I know how many lives she ruined.

What was my sister doing standing over Florence’s cot in the middle of the night?I trust my sister, Carrie, with my daughter’s life. But then she’s accused of a terrible crime. Carrie lives under our roof, she pushes my daughter on the swings, she takes her out for ice cream. You might ask, why do I let her? Why would I risk my darling baby? How could I let my sister stay? Because I have a dangerous secret too. One that only Carrie knows about. And if that secret gets out, I could lose my little girl....

Newlyweds Lina and Cain don’t make it out to their property on gorgeous Lake Tarawera as often as they’d like, so when Cain suggests they rent the house out to vacationers, Lina reluctantly agrees. While the home has been in her family for generations, they could use the extra money. And at first, Lina is amazed at how quickly guests line up, and at how much they’re willing to pay. But both Lina and Cain have been keeping secrets, secrets that won’t be put off by fresh paint or a new alarm system. And someone has been watching them.

When I wake up with the sun in my eyes the morning after my daughter’s birthday party, I know something is very wrong. I go straight to her room but feel a surge of panic when I see an empty bed. Downstairs everything is totally quiet, and the front door is locked. Why didn’t I hear her scream? Who took our little girl?
