Detective Harriet Blue is clear about two things. Regan Banks deserves to die. And she'll be the one to pull the trigger. But Regan - the Georges River Killer and the man responsible for destroying her brother's life - has gone to ground. And now Harriet needs to disappear too - before her colleagues stop her carrying out an act that could end her career, her freedom, even her life. Suddenly, her phone rings. It's him. Regan. And he wants to play 'catch me if you can'. Within hours Harry is following his clues along a path of devastation down the Australian south coast. Town by town, Regan is taking lives, and each one is someone she knows well. With both of them wanted on every newspaper and every television screen, time is running out. Harry needs to stop this killing machine fast before her chance for vengeance slips away.
