This book is over 21 hours. I love long books and usually will not take any less than 6 hrs. long. However, if the author had eliminated the duplicate and triplicate and quadruplicate information, this could have been an 8 hr. book and much more effective. He does assemble interesting and thought provoking information about each victim and makes pretty compelling scenarios for each assassination. But lose the repetition, by the end I was feeling like Collateral Damage!!
