This started out as a promising human portrait of Officer Tippit—something which doesn't seem to exist in many (if ANY) other books on the subject of Oswald's flight. Clearly well-researched and written, it also comes with the benefit of the Tippit family's input and support. But less than midway through, the tone changes and becomes increasingly repetitive and monotonous, as Myers continues to deliver the same scenarios through the eyes of multiple witnesses, when he could've relayed these once, much more concisely.
The author also comes across as being a bit too contentious with others who've written about the JFK assassination. No surprise, given the the epic controversy of the subject, but he seems to go out of his way to take certain writers to task; and at some point it just starts to grate away at what could've been a much more interesting story about Tippit's life, career, and final moments.
Another important detail: while I applaud the meticulous research and documentation that went into this, I was disappointed to find that literally half the book turned out to be appendix material and notes.
