I watched you move in next door and thought we might be friends. I saw you watching from the window - and knew I’d have to keep you well away from my husband. I started to trust you. Confide in you. I started to mistrust you. Suspect you. I was confused when I blacked out after an evening at your place. Was I really that drunk? I came up with a plan. A plan to make you both pay.

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.

I return home to our beautiful house on a chilly winter evening expecting to find my handsome husband Richard waiting for me by the fire. We’re still so in love, and he always takes care of me. He usually comes straight back from work. But tonight, our antique clock ticks on through the dark evening, with no sign of him. Then a knock at the door shatters my perfect life. A 12-year-old-girl, Alice from the village, has been found unconscious in the field behind our house. They say she was last seen getting into Richard’s car.

Ava only left her daughter in the pushchair for five minutes. The buckle was fastened, and she was sure it was safe.

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. 

Tucking her little boy Ollie into bed one night, Sarah notices his beloved teddy bear, which she bought him when he was born, is missing and in its place is a new toy given to him by her ex-husband’s new girlfriend, Laura. When she asks Ollie about it, he begins to shift uncomfortably before whispering, "Laura told me a big secret, and she said I can never tell you." Soon, Ollie is asking to spend more time with his dad and Laura, and shrinking away from Sarah. Then, when she calls to him in the garden one day, Ollie doesn’t answer back. 

I didn’t turn up uninvited. He asked me to come. He didn’t need to ask twice. He knew I’d agree. Kind Laura. Obedient Laura. Laura the soft-spoken schoolteacher with the faded cardigans and flat shoes. Nobody ever suspected someone like me would appeal to handsome, charismatic, happily married Ralph. I think even he was surprised by his choice. But I’m used to people underestimating me. But then maybe I underestimated Ralph, too. Because I never thought he’d be capable of doing what he did. It wasn’t only dangerous, it was very, very wrong.
