Saturday afternoon: youre with the kids in the garden when the phone rings. Its your best friend from school. Someone you havent seen for a few years. It should be a friendly call catching up on old times. But its not. This call is different. Your friend is panting with fear his breaths coming in tortured ragged gasps. Someone is inflicting terrible pain on him. He cries out & then he utters six words that will change your life forever...the first two lines of your address.
