Under the cold bright lights / Garry Disher.

"The young detectives think Alan Auhl is washed up, but that doesn't faze him. He does things his own way--and gets results. He still lives with his ex-wife, off and on, in a big house full of random boarders and hard-luck stories. And he's still a cop, even though he retired from Homicide some years ago. He works cold cases now. Like the death of John Elphick--his daughters are still convinced he was murdered; the coroner is not so sure. Or the skeleton that's just been found under a concrete slab. Or the doctor who killed two wives and a girlfriend, and left no evidence at all. Auhl will stick with these cases until justice is done. One way or another"-- Provided by publisher.
