I read Tomalin's Samuel Pepys biography (on paper) back when it was first published and enjoyed that, so I have no idea why I had not thought of getting the Dickens one before because I am a Dicken's fan, but I have it now.
Issybird,

I don't think I was aware of the Nelly Ternan biography so maybe that's another one to try and fit in sometime.
I am getting into the Austen one and am finding that very interesting.
