They say they have no children. So who did I see at the window?

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? And why can I hear a lullaby drifting across the garden when I'm tucking my own boy into bed?

Then, one night, I see a small shadowy figure in their bedroom window...

I thought I'd learned my lesson about trusting the wrong people, but now I'm forced to wonder what this perfect couple are hiding.

And if I try to save that little helpless figure in the window, will I do what I've always feared most, and put my beautiful boy's life in danger...?

An utterly gripping psychological thriller from the number one bestselling author of The Marriage and The Girlfriend. If you like Gone Girl, The Housemaid and Lisa Jewell then you will be hooked by The Bedroom Window.
