The "ghost" of 'Angus McCulloch' is in fact a conman called Patrick. He's in cahoots with Rachel Carlson's soon to ex-husband Brian and her supposedly best mate Sharon Winton. Brian has become so insanely jealous of Rachel's natural writing skills that he's set out a plan to make her crazy enough so that if she suddenly dies everyone will assume that she topped herself. Sharon has been encouraging him.
