Compulsion (Alex Delaware, #22) - Jonathan Kellerman

Seemingly random and unrelated acts of violence involving luxury vehicles sends a homicide detective and a psychologist on the haphazard trail of would-be suspects. Unlike other more contemporary murder mysteries that utilize a lot of forensic methodology to solve the case, this one relies on old-fashioned, nose-to-the-ground sleuthing. Eventually, a lead from a rather far-fetched and obscure source becomes the linchpin upon which the investigation is centered. For a work of fiction, this happenstance and timing of turning up with this clue is acceptable, but not quite so compelling in a real-life investigation. Other than this little 'observation', I enjoyed this read -- my first from this author.
