Author of the

Frankie MacFarlane, Geologist, Mysteries


I was raised in Pasadena, CA, educated at UC Riverside, worked all over the West, lived in the San Francisco Bay Area and Northern Virginia, and now reside in Tucson, AZ. My educational background is in the geosciences, social sciences, and liberal arts. I have bachelor’s degrees in history, anthropology, and geology, and an M.S. in Geology.

Before becoming a full-time writer I worked for the U. S. Government (primarily with the U. S. Geological Survey), conducting fieldwork in California, Nevada, Idaho, and Utah. Subsequently, I taught introductory geology and oceanography at the college level and offered short courses in writing, geology, paleontology, and oceanography in Tucson area schools. I am currently a Research Affiliate of the University of Arizona’s Southwest Institute for Research on Women and a SIROW Scholar ( I teach occasional writing workshops (e.g., Pima Community College West Campus, Pima County Public Library, Prescott Public Library, Sisters in Crime-Tucson, and Arizona Mystery Writers) and speak to groups about geoscience outreach through my mystery series.

For any of my readers who were wondering what I was doing before I launched the Frankie MacFarlane, Geologist, mystery series, you can check out the following US Geological Survey online publication (URL below):

Oberlindacher, H.P., Hovland, R.D., Miller, S.T. , Evans, J.G., and Miller, R.J., 2018, Geologic map of the Lower Valley quadrangle, Caribou County, Idaho: U.S. Geological Survey Scientific Investigations Map 3215, 6 p., 1 sheet, scale 1:24,000,

My writer’s residency with Pima County Public Library was a successful and fulling adventure. I thank the wonderful staff of Kirk-Bear Canyon library for welcoming me and facilitating my three-month sojourn. And I’m grateful to all the writers who attended my workshops and individual writing consultations. I look forward to catching up with your projects in the future.



Updates: All 6 Frankie MacFarlane novels were available as ebooks until three years ago. A big shout out to those readers who alerted me that the ebooks were no longer available. Texas Tech University Press has had a new part-time director since last September, and it seems  that TTUP no longer wishes to support the ebook versions of the Frankie MacFarlane series. But things could change, so stay tuned for updates. In the meantime, print versions of the books may still be ordered through your local bookstore,, or the TTUP website (

“Bury the Secrets Deep,” an historical short story, was published in And all Our Yesterdays, a collection released by Darkhouse Books (trade paper and E-book). Darkhouse has bundled the anthology with two other mystery/crime anthologies. It’s available online under the title The Darkhouse Books Collection – Volume One.

Another short story, “Case #15-4037,” was included in So West, So Deadly, a mystery anthology published by the Desert Sleuths Chapter of Sisters in Crime. And one of my poems, “Unharvested Water,” appears in More Voices of New Mexico (Paul Rhetts and Barbe Awalt, eds., Rio Grande Books/LPD Press; ISBN-10: 1936744295; ISBN-13: 978-1936744299). The books may be ordered via local bookstores, Amazon, and Barnes&

FRACTURE, geosleuth Frankie MacFarlane’s fifth adventure, is a quest mystery set in Tucson, Arizona and on the San Francisco Peninsula, California . The title refers to the San Andreas and related faults that mark the boundary between the North American Tectonic Plate and the Pacific Plate. The subject matter is timely. Since the release of Fracture in February, we have witnessed destructive quakes in New Zealand and Japan. The Japanese event was attended by an even more devastating tsunami.

(TTUP, 2008; ISBN: 978-0-89672-623-9)

(TTUP, 2006; ISBN: 0-89672-574-4)

DETACHMENT FAULT, the sequel to DEATH ASSEMBLAGE, is set in Tucson, AZ, and the borderlands of Sonora, MX.
