Great Mystery Recommendations?

Nevada Barr....the Anna Pigeon series. Love the settings.
Rita Mae Brown....a little simplistic, but enjoyable.
Janet Evanovich....fun, laugh-out-loud, sexy quasi-mysteries.
Anne Stuart - the Ice series
Charlaine Harris - the Harper Connelly series...not the Sookie books.
Kristine Kathryn Rusch - the Retrieval Artist series. Futuristic.
F. Paul Wilson - the Repairman Jack series. Otherworldly.
Aimee & David Thurlo - I've read parts of two of their series.
Pamela Morsi - fun, not mysteries
Susan Cummins Miller - the Frankie MacFarlane, Geologist series.

I also read urban fantasy....the mystery based ones.

I used to keep a computer file. Now I carry a tiny raw leather hand-bound journal to keep track of my books. Love carrying it! It's the size of the palm of my hand....love it!
