Query: Interesting, BUT...Disappointing

This is a fascinating topic, a real detective story for one of history's mysteries. (Though the mystery angle is not so great, just some minor twists and turns.) There is much in this volume that has been covered before---and done better (Trevor-Roper and O'Donnell, for example). The authors' arguments are poorly stated, disjointed, repetitive, and not particularly convincing. (Though they are probably---more or less---correct.) There's a rushed, let's-get-this-one-together-fast feel to the book (it's typos are both numerous and inexcusable). Essentially, what we've got going here is a refresher course. Interesting enough, but the billing far exceeds what's delivered between the covers.
