The attempted murder in 1984 of undercover policeman Michael Drury - shot while in his kitchen feeding his baby daughter - has been labelled the 'lowest of low' in Australian criminal annals. The compelling ABC TV mini-series Blue Murder brings this dramatic crime back into the spotlight. The case involves accusations of bribery, widespread corruption, betrayal and collusion and provides a rare insight into the mechanics of police culture. Former Detective-Sergeant Roger Rogerson's part in the affair is documented and reveals the intense struggle for power that existed in the NSW police force. That struggle - the pitting of one kind of policeman against another - has had far reaching consequences. Written in a pacy style and unfolding like a whodunit, Line Of Fire is a compelling story.
