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."

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.

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.

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?

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.

"Your son is missing," they say, and life as I know it is over. "Where would he go?" the police ask. "Where would he be?" my daughter begs. My heart races as images flash in my mind. The cabin we rent every autumn, surrounded by fiery-red maple trees. Voices raised. Tears falling. A marriage falling apart. And worst of all my husband telling our child, Theo, to run. The rest is a blank in my memory. If I close my eyes I can almost see it. A betrayal that has left me alone, in tatters, grieving for what we had.

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.

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.

My hand trembles as I stare at the anonymous text. On this sunny Saturday morning, our twin ten-year-old boys were playing in the park just down our tree-lined street. But only one of them has come home… and it’s all my husband’s fault. I race to Leo’s study and demand answers. As his face turns white, I know: one of his affairs has turned deadly. 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.

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.
