from "Robbie's Wife" by Russell Hill.

"Robbie's Wife" was a good read, a bit of James M. Cain goes to England if you will, and I mean that in the best possible sense. And while that quote is a little too on the nose and that character literally writes down each and everything that he experiences, it made sense within the plot.
Of course I can't imagine an actual screenwriter (the protagonist's profession) this side of Joe Ezterhas at his most self-indulgent, writing every other thing down in an almost verbatim fashion. So trust me when I say that unlike the police, I will not hold everything you say against you...
...unless it's juicy enough. Then, I'm at least going to change your gender and ethnic origin.
