Samela Harris, of the Adelaide "Advertiser" profiles Australian crime writer Garry Disher, on the eve of the publication of his fourth Inspector Challis novel, Chain of Evidence. Normally based on Victoria's Mornington Pensinsular, in this novel "Disher draws upon his memories of SA's arid Mid North. It turns out that Challis grew up just a bit further north - 'somewhere on the edge of the rainshadow'." Which sounds like it was just near where I grew up.
Update:
It seems I blindly followed in Haris's footsteps and got the title of the new Disher novel incorrect. That has now been fixed.
