Sophie King is missing.

Her parents, Harry and Zara, are distraught; for the last seventeen years, they've done everything for their beloved only daughter and now she's gone.

The police have no leads, and Harry and Zara are growing increasingly frantic, although they are both dealing with it in very different ways. Increasingly obsessed with their highly suspicious neighbour who won't open the door or answer any questions, they are both coming to the same conclusion. If they want answers, they're going to have to take matters into their own hands.

But just how far are they prepared to go for the love of their daughter?
