If you only read one book on the Lincoln assassination, this should be it. Michael Kauffman is the leading authority on the subject and his book is excellent reading. Once you start, you can't put it down. A few years ago, I had the pleasure of going on his tour of the Booth escape route and discovered he is a wealth of interesting information about Booth and Lincoln. I was so glad to learn he had completed his book and I understand why it has received so many rave reviews.
