Another spectacular start to a promised new series comes from journalist, biographer and former publisher Michael Duffy, who opens his first foray into fiction with a swan dive from an unfinished Sydney skyscraper onto the roof of a police car. A subsequent shootout rattles Detective Nicholas Troy, who always believed himself an honest copper doing an honest job – but this is just the start of his trouble. Battling indifferent and corrupt colleagues and threats to his family’s safety, Troy must now navigate the filthy heart of his city, a ‘City of Sharks’, where the only rule seems to be looking after yourself.
