The Girl Before meets The Couple Next Door in a Hitchcockian thriller about a couple who moves into their dream neighborhood only to discover nothing is as it seems... The perfect couple. The perfect house. The perfect crime. Londoners Jack and Syd found their dream home: lots of space, a great location, and a friendly owner who wanted a young couple to have it. Everything is exactly what they hoped for when they move in--except Jack makes a disturbing discovery in the attic, and Syd begins to wonder about the girl next door. And they each keep the other in the dark. A mistake. Because someone has just been killed outside their back door, and now the police are watching them. This is their chance to prove they're innocent--or to get away with murder. Whose story do you believe?
