This novel is perfect for the business traveler looking for a great plane read. I finished the book in about 3.5 hours. I've read my fair share of spy novels--it's a vice of all men I think, and I found I-72 to be one of the closet novels to showcase how old-school Human Intelligence (HUMINT) actually works. Nothing in that world was written down, no one had on-line profiles--it's all based on trusted relationships and memory. The main character, Grant Thurmond, is a grizzled and chiseled relic of a forgotten era of HUMINT with one last chance to prove he still has usable skills in today's tech-driven, on-demand world. There's just one problem; HUMINT takes time, and that's one luxury Thurmond doesn't have. So, with the help of his supporting character, Sam (Samantha), this old dog has to get with the program. Reminiscent of Bruce Willis or Clint Eastwood, Thurmond is the kind of character that likes his coffee a few days old. The Russian car chase scene is worth the read alone!
