The gripping new thriller from the No. 1 bestselling author of The Couple Next Door.

******

It can be hard keeping secrets in a tight-knit neighbourhood.

In a tranquil, leafy suburb of ordinary streets ? one where everyone is polite and friendly ? an anonymous note has been left at some of the houses.

?I?m so sorry. My son has been getting into people?s houses. He?s broken into yours.?

Who is this boy, and what might he have uncovered? As whispers start to circulate, suspicion mounts.

And when a missing local woman is found murdered, the tension reaches breaking point. Who killed her? Who knows more than they?re telling? And how far will all these very nice people go to protect their secrets?

Maybe you don?t know your neighbour as well as you thought you did . . .
