Gun Control is 2015 Australian novel by Peter Corris featuring private detective Cliff Hardy. It was the 40th in the series. Reception. The "Sydney Morning Herald" wrote that in the novel "we're off to Katoomba in the Blue Mountains, about which Hardy 'like most Sydneysiders', is ambivalent: 'We're glad they're there but, with snow in the winter, searing heat in the summer and no significant sports venues, we feel it's a kind of foreign territory to be visited very selectively.' These are the kinds of passing comments about people and place that have always been the real delight of these books."
