I found this book to be very uneven in quality. I am an avid reader of material related to the Lincoln assassination, and I approached this book expecting it to be interesting if for no other reason than its relevance to that historical event. However, I found the book to be exceptionally boring and slow in its beginning, so much so that after about a fourth of the book I put it down expecting not to finish it (very unusual for me). The characters were dimensionless, stereotypical, and uninteresting, and at many points the characters' psychology and the central sexual/romantic liaison struck me as irritatingly inauthentic for the period depicted. However, I did return to the book--skipping right to the assassination scene itself since the first part was so damned boring. From this point forward, the action got really engrossing and suspenseful, and the book became one that I couldn't put down. The action was very well paced, though the main characters' personalities and their relationship to each other still seemed inauthentic--or at least the book left me wondering how much of these depictions were rooted in fact and how much they were pure fiction. It would be nice for the author to clarify which elements or dimensions of the story are historically known and which are his own invention. In the end, it was a book that was very memorable, one that really impacted me insofar as it has changed my notions of this who this couple was. But again, I wish I knew whether my new understanding of their personalities and their relationship--and of the assassination's apparently lasting dominance over their lives--derives from an accurate or a purely imaginative portrayal of the characters.
