Garry Disher on the fifth in the Hirsch crime thriller series, 'Mischance Creek'

Constable Paul Hirschhausen is checking firearms. The regular police audit: all weapons secured, ammo stored separately, no unauthorised person with keys to the gun safe. He’s checking people, too. The drought is hitting hard in the mid-north, and Hirsch is responsible for the welfare of his scattered flock of battlers, bluebloods, loners and miscreants.

He isn’t usually called on for emergency roadside assistance. But with all the other services fully stretched, it’s Hirsch who has to grind his way out beyond the Mischance Creek ruins to where some clueless tourist has run into a ditch.

As it turns out, though, Annika Nordrum isn’t exactly a tourist. She’s searching for the body of her mother, who went missing seven years ago. And the only sense in which she’s clueless is the lack of information unearthed by the cops who phoned in the original investigation.

In this episode Gregory Dobbs chats to Garry Disher about the character of Paul Hirschhausen he originally envisaged, how his own research into far right and sovereign citizen groups turned out to be very timely, and why small town Australia is defined by the people who live there.
