This was a really fun read. I heard about it from the Sunday strip of 'Unshelved'. It's about Darwin, an accident reconstructionist with a PHD in Physics, who works for a PI firm that specializes in insurance fraud in California. He's a little too good at his job and he soon has all sorts of weapons aimed at his person. Because of this he has to brush up on his old Vietnam skills and marry them with his physics to keep alive and catch the bad guys. They actually work out physics problems on the page like D=V/T2. It was cool.
Just to tell you the tone of the book... Occam's Razor = The simplest solution is the correct one. Darwin's corollary = the simplist explanation is stupidity.
