Tucked away in the Southern Highlands of New South Wales is Cork Valley, inhabited by hard-drinking Irishmen. Here an Excise Officer looking for illicit whiskey 'stills' has been murdered, and it's Bony's job to find the killer. Disguised as a horse-thief, the Aboriginal detective hitch-hikes into the valley to meet a lawless lot…

Written by Upfield while living in Bowral, Cork Valley is actually Robertson.
