(Later) OK, I just did. It's a huge article! However, rather than doing a full review, perhaps one or two small comments might be helpful?
1. I wonder whether it might not be wise to give the second François his full name of 'Hercule-François'?
2 I seem to recall that Catherine actually *designed* Chenonceau. You may care to check.
3. Catherine was, I believe, one of John Knox's famous 'regiment (i.e. rule) of women' (Catherine, Mary, Mary of Guise?): might it be worth mentioning?
4. Legend has it that Catherine was a great poisoner: they still show you her alleged 'poison cabinets' at Blois!
5. For more light on her activities, see Prosper Merimée's 'Chronique du regne de Charles IX', mere novel that it is.
5. Check the spelling of 'surprisedn'?  Best
