Barry followed through on his promises. I met track owners and managers, sports journalists, pit crew chiefs, and fans who had driven their Winnebagos from Portland, Houston, Teaneck, and Nashville. Thanks to Barry and the Smith family I enjoyed a top to bottom tour of the Charlotte Motor Speedway. My fascination with the adjacent landfill was, I fear, a source of some dismay.

2. Flash and Bones takes place entirely in Tempe Brennan’s hometown of Charlotte. Spider Bones, on the other hand, begins in Montreal, where Tempe occasionally works, then moves to Hawaii. Other books have taken Tempe to Chicago, Israel, and Guatemala. How do you decide where to set your next novel? In what city do you spend most of your own time these days?

Setting is a living, breathing part of each story I write. When Tempe travels, her destination is always a place that I know well, one in which I have plied my trade or spent time doing research.

I work and live in Charlotte, so Tempe does, too. Like her, I am a commuter, shifting regularly from North Carolina to Quebec, where I consult to the Laboratoire de sciences judiciaires et de médecine légale in Montreal. Yep. I have the mother lode of frequent flier miles.

In Spider Bones Tempe heads to Hawaii to pursue a case for JPAC, the Joint Prisoners of War, Missing in Action Accounting Command, the U.S. military facility dedicated to identifying the remains of servicemen and -women who have died far from home. Easy choice. I consulted for this lab for many years.

In Grave Secrets Tempe exhumes a mass grave in Guatemala. In the year 2000 I was invited to do the same by the Guatemalan Foundation for Forensic Anthropology.

In Bones to Ashes a case takes Tempe to Tracadie, New Brunswick. This setting was suggested by an exhumation and analysis I performed for an Arcadian family living in that province.

In 206 Bones Tempe flies to Chicago. Another no-brainer. That’s where I was born.

You get the idea. It’s better to observe firsthand than to make things up.

3. Another dominant theme of Flash and Bones is right-wing extremism, a subject about which you’ve written before. Members of a white supremacist group figure as suspects in the book. How did you become interested in these factions of American society?

Extremist ideas do not offend me. In my view, people are free to believe what they will. Extremism that hurts others offends me greatly.

In Cross Bones I wrote of religious extremism—belief systems that refuse to accept the legitimacy of differing worldviews. In that story events take Tempe to Israel and bring her into contact with fringe groups who use violence to impose their ideologies and customs on others.
