In the 40th Cliff Hardy book, Hardy plays a cool hand as a decades-old crime resurfaces and old scores are settled. Is Sydney gun city? It certainly seems so when Cliff Hardy is hired by entrepreneur and one-time pistol-shooting champion Timothy Greenhall to investigate the violent death of his troubled son. Soon Hardy is pitched into a world of crooked cops-former members of the Gun Control Unit-outlaw bikers, and honest police trying to quietly clean the stables. Two more murders raise the stakes, and relationships are stretched to breaking point. Hardy hooks up with a determined policewoman and forms an unlikely alliance with a charismatic biker chief. Uncovering the tangled conspiracy behind the murders takes Hardy to the Blue Mountains and Camden, to plush legal chambers, and a confrontation in an inner-west park-all against the roar of 750 cc engines.
