The Right Jack by Margaret Maron; Rosemary Harris website
If you want you admire sheer craft and have a great good time while you're doing it I'd recommend reading The Right Jack by Margaret Maron.
Even though the main story revolves around a bomb exploding at a cribbage tournament--and I have zero interest in games of any kind--the story held me tight all the way through. Maron is excellent at setting scenes, finding ironies and deceits in every day conversation, and creating vivid and compelling characters even when they're eccentric. Her Homicide Detective Lieutenant Sigrid Harald has enough psychological ambiguity to really work as a lead.
If you're up for a traditional mystery with a unique setting and a plot that will keep you turning pages, this is it.
