If you have read and enjoyed "Henry Esmond" then you will certainly want to read this and find out what happened to some of the characters and their descendants, but beware. It's very long and some of the episodes are tedious. Not that it is a bad book - there's plenty of Thackeray humour and plenty of historical interest.
The title characters are two Virginian-born twin brothers, and the novel revolves about their adventures and misadventures in late eighteenth century America and England. Wolfe, Washington and Dr Johnson all play significant roles, and the twins end up on opposite sides in the American Revolution. An intriguing thought conjured up by the story: if Wolfe had survived Quebec and stayed in North America, would the revoltion even have started?
I found the "theatrical" sections in London particularly uninspiring - I think Thackeray was trying to create a vicarious stage career for himself - and this particular edition suffers from the absence of any explanatory notes at the back. Nevertheless, I'm glad I finished it. Worth a go!
