The women have supported each other as they have shared the joys and trials of motherhood, but now everything has changed. There's been a terrible car accident, an unimaginable tragedy that leaves both families devastated.

There was so much anger brewing in the child that sometimes Alicia feared for all of them. And now she had gone and done this terrible thing. This terrible, terrible thing. Tara has lost her voice. She knows there was pain and fear, but she cannot remember anything else. Now she can answer the questions only with silence. Minnie has buried her voice for years, losing herself in silence and isolation, keeping her secrets safe and her broken heart concealed. Liam finds refuge in silence; it is a place to go to when he cannot get the words out.

Once, so very long ago, she watched him like this when he came to pick her up from a date. Her stomach fluttered and burned with infatuation and desire. She would watch him walk up the path and think, 'This must be love.' But that was so very long ago. Now Liz is wary and afraid. She has made a terrible mistake, and it cannot be undone.

All Malia needed was a single litre of milk, and now she's surrounded by police and Zach has disappeared. Detective Ali Greenberg knows that this is not the best case for her - not with her history, but she has to get back to work at some point. Edna is worried about the new residents at the boardinghouse. She knows Mary would turn in her grave if she knew the kinds of people her son was letting in. And then there is someone else. Someone whose heart is broken.

I gaze at my husband’s once handsome face, so still and pale in the hospital bed. The doctors say I should keep talking. He might be able to hear me even after the terrible accident that left him fighting for his life. But all I have to whisper to my husband is this: "I know what you did."

In the middle of the night, Claire wakes up to discover that her beloved daughter, Julia, is dead - and life, as she knows it, is over. Searching for answers, Claire stumbles upon a pile of letters, hidden under Julia’s bed in an old, battered shoebox, and feels closer to her daughter than ever before. They tell her that Julia was happy, that she was thriving at university, that she was in love. But as the letters go on, Claire starts to feel uneasy at something hidden between the lines. Even as she grieves, she must prepare to face a shocking discovery.

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.

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.

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.

If you passed Alice on the street, you couldn’t help but smile. At how she holds hands with her husband, Jack, who she has been with since she was at university. At the way she admires her three boys, the center of her universe. But if you looked very closely, you’d see how tightly she holds Jack’s hand, afraid to let go. You’d see how carefully she watches her boys, scared to look away. She has told Jack that she ran away from home when she was younger - but she didn’t tell him the whole story.

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.

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.
