As I noted before, in attempting to direct the police he says: "you come to the clubhouse, you come straight in, and make a left.... actually you would go past the clubhouse...[] no you go in straight through the entrance and you then make a left... er... you go straight in, don't turn, and make a left..."
He's clearly describing how to get onto Twin Trees Lane, but never actually uses the street name. Even if he couldn't give an exact number, not saying, "it's on Twin Trees Lane," seems an astounding omission for someone who lives in one street away.
