I heard about the book series from podcacher.com, a geocaching podcast and first read "Cached Out" on the Kindle. I liked that one the best but the others were good, too. "Fatal Dose", "Held for Ransom", and now "Death Row", all about solving problems to arrive at the destination, much like a geocache puzzle. In Death Row, I first thought the premise was a bit of a stretch, but soon realized there are enough crazy people, political or not, professional or not, male and female, etc. who could pull off a crime like this. I also paused to consider how someone could be assumed to be guilty with overwhelming evidence otherwise. Then I was reminded of how often this happens in other circumstances. Also, the view into the FBI was quite interesting although I was surprised by Cliff's balancing between law as seen by the FBI and law as seen by the the lawyer. The fizzy challenge aspect was appreciated but I am so far from that myself. I solved the puzzle in the book as well. TFTB (Thanks For The Book).
