Pitch's book is definitely one that someone getting interested in the details of the assassination should read. I was a tad disappointed because he had promised "new finds," but I didn't see any. Another book in the same vein that I enjoyed a great deal is Tom Goodrich's The Darkest Dawn.
I am also enjoying John's Decapitating the Union, but it's making me struggle! So much information to digest and so much "surmising." I'm just delighted that he decided to tackle "the Confederates did it" angle. I want Tidwell, Hall, and Gaddy to be vindicated in the end.
