Elizabeth is Joe’s foster mother, but she loves him like her own. The five-year-old, who adores superheroes and watching the birds outside, is the child she has dreamed of. As she looks into the garden, where he was playing just moments ago, her heart feels like it has been ripped from her chest. She was meant to save Joe from his birth mother who almost harmed his chances at life. The woman who has been trying to desperately get him back. She was meant to protect Joe from her husband. The man who, right now, lies to the police, saying he was making breakfast when Joe disappeared.

Her chest tightens, her heart speeding up. The kitchen is chaos. She steps on something hard, and looks down. Toy dinosaurs are scattered everywhere. But her son is nowhere–her baby boy is gone.

Two days ago, the Wilson family checked into the imposing, glass-fronted Lodge, surrounded by snow and perched perilously on the edge of a cliff looking out to a gray sea. Not everyone was looking forward to the family get-together. But mother-in-law Angela insisted the winter trip would help heal their rifts....

Caro and Anna are best friends...they were best friends. Over a decade, Caro and Anna have bonded while raising their daughters, two little girls the same age but living two very different lives.

There's been a terrible car accident, an unimaginable tragedy that leaves both families devastated.

In the wake of my darling husband’s death, I am so lucky to have my three beautiful, grown-up daughters by my side at our holiday home in Scotland. We need some time together to recover from the shock. But I also need to set some things straight about their beloved father....

I am cooking spaghetti, his favourite, while he plays in the garden. But when I look up, he’s gone. I call the police, my hands shaking so much that I hit the wrong digits twice. "My son is missing." When the police turn up, I’m trapped in the web of my lies. I have hidden the truth from eight-year-old Riley, my little boy who loves climbing trees and always has scraped knees. I have hidden my secret from everyone.

It’s the phone call every mother dreads. I’m climbing into the car after a trip to the grocery store. As the engine starts, my phone rings. It’s my stepdaughter, Shelby, who is babysitting my three-year-old Millie. "I only went upstairs for a second," she says through her sobs. "She’s gone." When the police turn up, Shelby’s story starts to unravel. What is she hiding? Then I get a message saying, "Your husband is not who you think he is." Suddenly, my family feel like strangers. Everyone has a secret - even me.

I never thought I would end up here. Alone, in a cold one-bedroom apartment, only seeing my precious daughter once a week. Another woman is living the life that was once mine. I wish I was still married to my ex-husband, the love of my life. I dream of tucking my five-year-old child into her ballerina bed sheets every night. I miss living in a beautiful house, the perfect family home, with a winding staircase and a sprawling garden. I’d do anything to be with my family again. To start over and prove to them that I’ve changed, that I won’t lose control like before.

Every family has secrets, and on the hottest day of the year, the truth is about to come out. As a tragedy unfolds behind closed doors, the dawn chorus is split by the wail of sirens. And one by one the families who tried so hard to welcome the Wests begin to realise: Hogarth Street will never be the same again.

I gaze at my new husband and smile. It’s our wedding day and I feel like the luckiest woman alive. Lucas is perfect. He brings me coffee in the morning, flowers in the evening, and never leaves the room without a kiss.

Esme is a start-up success who runs her own successful media company and heads up a series of investigative podcasts. She also has a beautiful home, where she lives with her sister, Michelle, and her son, Zachary. Sure, there’s an ex-husband hanging around - Owen likes to pop round a bit too often - but everything is civilised and amicable. She has life all tied up. But Esme knows that any successful podcaster is only as good as her last story, so she sets out on a new series of interviews to get to the truth behind Simone Fischer’s high-profile murder of her husband.

You tell him everything. The husband you adore, the father of your child, your best friend. He knows, just by looking at your sage green eyes, when something is wrong. The two of you can communicate with a glance or a touch of the hand. Except what if you can’t? What if your happy marriage has plastered over one huge lie? A lie you have even started to believe yourself in order to survive?

They find her just as the sun is beginning to rise in the early morning mist. They had begun at dawn, the group of searchers keen to get going. A missing child spurred everyone on. In the end, it was a flash of color, a bright neon pink that caught her eye. They had been looking for pink. Nothing tests your faith like being a mother. The first time your children walk to school alone, their first sleepover, when they finally fly the nest. As a parent, you have to believe that everything will be ok.

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.

Her chest tightens, her heart speeding up. The kitchen is chaos. She steps on something hard, and looks down. Toy dinosaurs are scattered everywhere. But her son is nowhere–her baby boy is gone.

Katelyn smiles around at her husband and friends, gathered to celebrate her 36th birthday in their beautiful home decorated with fairy lights. But the next day Katelyn wakes up shaken and terrified in a hospital bed. She doesn’t remember the sweet taste of birthday cake icing, or how angry her best friend was at midnight, or the terrible things her husband said. She doesn’t remember the party at all.

I stare at the photo of my beautiful daughter. Her hair is shining and her face is lit up with a smile. The man with her looks so happy too. But my mother’s instinct is screaming. I know something is terribly, terribly wrong. And I know what I have to do… I wish I could hold her tight. See if she still wears the same perfume she always wore. But my daughter blames me for her father’s death. She won’t even talk to me… I just know she isn’t really safe with her boyfriend, Garth. I will keep my distance and I will just watch her. For now.

I always smell the unfamiliar perfume on his shirt. I try to pretend we are a happy family, for the sake of the children… but now, my child is in terrible danger.
