Fantastic book! Howard Donahue was an amazing expert, thorough, careful, completely mathematical and objective, and as unrelenting as a dog with a bone. He spent years to reach a shockingly logical conclusion to the mystery of who actually fired the shot that killed JFK. Donahue suffered for his brilliance, as did the intelligent author Bonar Menninger. Read this book!! It is extremely well-written and presents a theory which makes total sense - and which explains the cover-up that goes on to this day - even though almost all the players are dead. This is an important and much-suppressed book! A must-read, esp. for anyone who was alive on Nov. 22, 1963. You will appreciate knowing at last. Five Stars !
