I’m still reading the Shelley biography. Remarkably, his personal life seems to have stabilised somewhat, I suspect mainly because his grandfather died and so, while the exact terms of the legacy are still with the lawyers, he’s not actually having to hide from the bailiffs any more.
The chances of his life running smooth are reduced by the fact that, as well as being atheist, vegetarian, republican and probably revolutionary, he’s a believer in free love of a rather high-minded sort. So the second wife in succession has had to deal with him being keen to share her with his friends. And what she seemed to find even more difficult, it rather looks like she was having to share him with her sister. The exact details are a bit conjectural because apparently there are lots of diary entries torn out from the relevant period.
It’s like Hello! for people who can’t bring themselves to read the real thing. Though I don’t suppose Jude Law’s love notes to Sienna Miller are couched in terms of high-flown philosophy.
