Minor in Possession opens with Seattle homicide detective Beaumont drying out in an Arizona rehab clinic. Despite non-stop rainshowers and a rising river, Beau is still a fish out of water, trying to cope with a soon-to-deceased roommate, hostile clinic staff, and visiting family members dredging up his unfortunate past. It'd be enough to drive a person to drink, except of course that's the reason he's in rehab to begin with.
Following his roommate's demise and an attempt on his own life, Beau finds himself on both sides of the investigation and travelling around the state in an ever-increasing number of rental cars. The action is fast, and so are some of the women he meets. The ending is a bit overly sentimental, but getting there is certainly fun.
I thoroughly enjoyed this book. My only caveat is don't let this be the first J.P. Beaumont mystery you read. If you're not familiar with the Seattle detective's history - his lifestyle or marriage to Anne Corley, for instance - read Until Proven Guilty or the more recent Partner in Crime before reading this novel. References to Corley and things like Beau's Porsche are dropped in unaccompanied by much context, which is unusual for Jance. Unless you know what she's talking about, you'll be as much a fish out of water as her detective is at times while tackling this mystery.
