Right, am in a better mood so have things to say.
Eustacie is another typical GH heroine of the early mould - young, unworldly, devoted to her chevalier, headstrong, etc - but she is more engaging than some others (puts Cleone in the shade, for example). And we also get the other kind of GH heroine, the more interesting one, the twenty-something whom nobody else has wanted to marry. Abigail Wendover and Ancilla Trent are also in this category. And I do like them better as it's easier to pretend I am them because they are more sympathetic and they don't appear by and large in Austen/Bronte/etc, Anne in Persuasion being a notable exception.
Eustacie has blue eyes; Sarah, grey. Just saying...
Eustacie in drama queen mode is splendid, and it is delicious parody of other novels - the long speeches about white frocks and tumbrils which Tristram dampens with realism...!
I think GH must not have been a morning person, or possibly her husband wasn't, because every book has something about being a morning grump - here we have:
Sir Tristram was contemplating with grim misgiving the prospect of encountering vivacity at the breakfast-table for the rest of his life, and Eustacie was wondering whether her betrothed was capable of uttering anything but the most damping of monosyllables..
In Civil Contact GH uses the equivalent scene to show how suited Jenny is to Adam - she lets him breakfast in peace even though she is bored and wants to talk.
I love Sarah's sense of humour. I'm not sure she says what she means once in the book. Certainly when she is talking to Eustacie she is hamming it up something rotten. I'm not sure how desperate her position was - her travels with her JP brother, unencumbered by a SIL or companion, sound like fun but perhaps weren't sustainable. Presumably he was required to work occasionally - quarter sessions ring a bell. And I think it would have been quite lonely. GH heroines are not frequently used to thinking of their own comfort.
More awkward "wondering accents", notably the smugglers free traders, but also Eustacie's French.
G2g - screaming toddler wants only me. More thesis thoughts later.
