Improbable Cause (J. P. Beaumont Series #5) » (Reissue)

You might call J. A. Jance a true town and country novelist, since she writes one series set in Seattle and one in small-town Arizona as she shuttles between the two in real life. In big-city homicide detective J. P. Beaumont and in small-town sheriff/mom Joanna Brady, Jance has created two mega-popular mystery franchises.

When a dentist is killed, Detective Beaumont discovers that the victim was a despicable character that society is well off without. And Beaumont soon begins to wonder about real justice as he unearths an unlikely bunch of vigilantes.
