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.

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.

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.

Rachel is afraid she may have done something terrible. She's sitting in a room, being asked whether she killed someone. She doesn't understand how her life has changed so completely. When she was younger, heads would turn when she walked into a room. Her children needed her; her husband adored her. But somehow the years wore that all away. She was so busy raising her children, looking after her parents.... 

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.
