While visiting his dying father in his childhood home in the dusty, hardscrabble South Australia town of Mawson’s Bluff, Challis unofficially investigates the mysterious disappearance of his sister’s husband, Gavin Hurst, from eight years earlier. Hurst is a man not readily missed by many of Mawson’s Bluff’s residents and his disappearance is truly a mystery. His truck abandoned at the desert’s edge, his body never found.
Back home at the Waterloo Station, Ellen Destry is filling in for Challis during his absence, a girl is kidnapped on her way home from school. She is found imprisoned in an uninhabited house. Abused by what Destry believes is a pedophile ring operating in the Peninsula. Her investigation hits roadblocks from within the police service and the only person she can trust is Hal Challis, more than 1,000 kilometers away.
Chain of Evidence is a powerful and disturbing procedural. The two major mysteries are intriguing and executed with the sure hand of an absolute professional. It is Ellen Destry’s coming out as an equal partner with Challis. The setting, both the Peninsula and Mawson’s Bluff, is rendered with a muted artistry and adds immeasurably to the novel’s power. There is nothing gory or exploitative about either storyline and Mr. Disher has a way of mixing character stereotypes to develop tension between the characters, the plot, and the reader. It may be the best book in the series. If you are new to Garry Disher, Chain of Evidence is a very good place to get acquainted.
