<p>In the 40th Cliff Hardy book, Hardy plays a cool hand as a decades-old crime resurfaces and old scores are settled.</p><p>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 bikies and honest police trying to quietly clean the stables.</p><p>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 bikie chief.</p><p>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.</p>
