When a top British police chief arrived in Australia to take charge of one of the world's most corrupt forces - and also run security for the 2000 Olympic Games - he was thrilled by the challenge of the job.
The following six years saw triumph, betrayal, Byzantine politics, unprecedented public support and unrelenting media attacks as he battled for control of the New South Wales Police Service against almost fanatical resistance to change.
Finally, the truth can be revealed about Peter Ryan's pay rise, that London job, the Olympics, the Cabramatta debacle, the bizarre legal machinations that led to the end of his 41-year police career, and his fears for the future of democracy in Australia.
Peter Ryan: The Inside Story offers a searing insight into the private laughter and tears as well as the brilliant career and ultimate downfall, of the man who was both the best loved and most-vilified Police Commissioner Australia has ever known.
