I purchase the "Assassins Doctor" by Robert Summers late last year. I've thumbed through it, and it looks real good if you are interested in this side of the assassination story, the reviews on Amazon are good. It's a big book at 700+ pages, you will get your money's worth. I look foreword to reading it this year. Bob's a member here, read a few of his posts and you can tell he knows his subject.
