'The godfather of Australian crime fiction.' 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 750cc engines.
