The unlikely not-quite-married couple of Fiddler (hard-boiled P.I.) and Fiora (semi-psychic financial wizard) takes on jealousy and greed in winedom's fabled Napa Valley. While not one of the couple's most remarkable adventures, perhaps, it's still entertaining -- and informative, too, both about grape-growing and wine-producing, and about Fiddler's own shadowy (and very personal) past. This series is very human and literate at the same time, and highly recommended (though, sadly, too often out of print).
