My husband and I are fighting for our lives in hospital after a terrible car accident. But despite my pain, all I can think about is what our families will find behind our front door. The scarf that has been all over the news, belonging to a dead young woman with honey-coloured hair. I have to speak to the police before my husband can. I’m drifting in and out of consciousness, but when I hear my wife talking to the police, accusing me of the murder of an innocent woman, a cold fear grips me. I know I’ve got a temper.

Not long after receiving a devastating medical diagnosis, Amy Cooper is at the police station—reporting the disappearance of her husband, Callum. A few miles away, a mother and her children are outdoors enjoying a day in the snow when they discover a dead man in a ditch nearby. The mother calls the police, whose initial investigation indicates the body belongs to the missing husband, killed in a hit-and-run. But the autopsy results reveal to DI Samantha Freeman and DS Jenny Newcombe that the man didn’t die in a car accident.

My darling little boy Albie adores playing at our new neighbours’ house. And after the terrible year we’ve had, I feel so lucky that we can start over in this perfect place, with new friends who treat Albie like the son they never had. He can’t stop talking about the tree house they’re building him, and the cookies they bake together. But as time passes, something starts to feel wrong. Why don’t they ever open the front door more than a crack? They told me they had no children so who does the small pink tricycle I saw in their hall belong to?

Alice and Seth are a perfect love story: the handsome doctor and his beautiful fiancée. They’re wealthy, well liked and made for each other—the envy of all their friends. Alice can’t wait for the day of their dream wedding. But when she arrives at the altar, she doesn’t recognise the man waiting to marry her. When this stranger insists he’s Seth, her husband-to-be, the entire congregation seems to agree. Even her parents try to persuade Alice to go through with the wedding.

This holiday is the first time my husband Jeff and I have been on our own in years, and I want it to be a fresh start. We can walk along the beach, eat ice cream in the bright Spanish sun, and fall in love again.
