This year, Nicky Hager released a book which led to two government inquiries and a police investigation.
The inquiries were into other people - but when the police came knocking, it was Hager's door which was the first to be entered.
Dirty Politics was an election bombshell, although it has inflicted no mortal wound on anyone named in it. The book described a conspiracy of a highly dubious nature, claiming John Key's government worked with blogger Cameron Slater to dish dirt on opponents. There were claims he carried out "hit jobs" for hire, attack blogging on a commercial basis.
The details revealed in the book saw great pressure placed on Mr Key and Justice Minister Judith Collins, a friend and supporter of Slater and his Whale Oil blog. Her job went amid allegations she was working with Slater to undermine one of her public sector chief executives.
