Keiran gets on a plane across the ditch to her old home, New Zealand, to track down one of the main suspects in Juanita Nielsen's suspected murder ... with unexpected outcomes. Back home, a new lead unearths someone who's never spoken before. The man was a young law student recruited by police to go undercover inside jail. He tells of a terrifying cat-and-mouse encounter that led to a detailed confession of murder. The sting also reveals a money trail involving crime boss Abe Saffron and an alleged attempt to influence the outcome of a court case. Both potentially game-changing revelations, the investigator claims, were ignored or buried by senior police.
