The author's thesis boils down to "eight assassination attempts secured the preservation of the British monarchy". This thesis is not defended well enough to make the book worthy of its length. Also, there are over 100 pages of endnotes; 1/6 of the book is endnotes. No. An interesting thesis that goes nowhere, and a book that was good enough to make me realize that I don't care a bit about the monarchy, its supporters or detractors, nor do I care about its fate.
