I did enjoyed this book, Desmond Seward has a very easy writing style and it was very refreshing to read a book on Richard III that wasn't either gushing or endlessly defending him on every point to justify this historically "maligned" figure.
However I do have one or two issues which irritated me a little. Obviously the author is writing from a negative perspective, but as a result he sometimes comes across as patronising about Richard, northers and even short people, which although not a major issue annoyed me.
Secondly, using Sir (Saint) Thomas Moore as his primary source, the author constantly quoted him then suddenly became somewhat cautious of him entirely. This sometimes confused me.
Ironically, after reading this book I felt a little bit sorry for Richard, something I didn't expect (I personally believe he was responsible for the murder of his nephews and was generally a bit of a black sheep) I would recommend this book, but only as part of wider research.
