Until the girl went missing, we thought it was the perfect place to live... When we move into the exclusive Westford Park housing estate, we feel safe at last. More like a country club, it has everything we might need - beautiful houses with big gardens, a pool, a boating lake, extensive grounds. It's also got 24/7 security. Our new neighbours are lovely too. We start to make friendships that feel like they could last a lifetime. It feels like nothing could possibly go wrong here. It's like our secrets haven't followed us here. Or that's what we think at first...
