The third book in the Peter Clancy series sees him in London, working for one of the "red-top" gossip newspapers and getting his love life all out of control. Not sure why these books aren't getting more attention - it's a great series.
From the Blurb:
Australian journo Peter Clancy is in London this time, working for a notorious scandal sheet. While writing salacious stories on celebrities, Clancy poses as a biographer to dig the dirt on drug- and alcohol-raddled Olivia Michaels, once a star of the screen.
