I noticed from reading the Guardian book reviews on Saturday that there is a new bigraphy of Mary just out, by John Guy.
The review says:
"On to this already crowded stage steps John Guy, with the aplomb of a magician about to pull several large, lively rabbits from the hat. In a surprisingly partisan new biography, there is scarcely a single aspect of her life to which he does not give a twist."
It seems he has a new view on who concocted the Casket Letters:
"It is nothing new to suggest that they were a forgery, albeit concocted from genuine letters written either by other parties, or by Mary herself at times and to people other than those alleged. This, broadly speaking, was the conclusion Antonia Fraser reached in her landmark biography of Mary more than 30 years ago. But the devil is in the detail here. Guy, returning to the archives and examining all the documentation in a way no one has done for more than a century, provides a riveting new analysis of who wrote what, and why. His personal devil has a face, and it looks much like Elizabeth's chief minister, William Cecil. "
Anyhoo, the full review can be read at:
