Grave Secrets by Kathy Reichs

Again, I remembered the scene setting at the beginning - both of them actually. The unearthing of the mass grave in the Guatemalan highlands was certainly memorable, and who could forget the body in the septic tank? Those were both drawn in so much detail that I remembered them as the openings of two different books. Actually, it turns out that, although everything is thoroughly entertwined, neither of those is the set up for the main thread of the story.

This one has it all - genocide, adultery, abuse of political power, obsession, mistaken identity, and murder for profit. Besides all that, this time Tempe is poisoned.

On the home front - almost all of the action takes place in Guatemala, just one quick trip to Montreal for a couple of reasons - one of which is some technology that is not available in the third world. The local cop with whom Tempe must deal turns out to be Ryan's old college buddy. And trust Ryan to find good reason to accompany Tempe back after her run to Montreal. Naturally, both of them are pursuing and Tempe is tempted.
