This is a critical theory about the use of the blush in 19th century fiction. By looking at Austen, Gaskell, Dickens, James and other authors of the time, she reveals the evolution of the blush from something that betrays the blushee, to a more calculated devise that defines social mores.
This should be a text in any college curriculum on Victorian Literature. The author deftly applies the techniques used by Barthes and others to look at the use of the blush in a number of books of the period. What would seem a casual aside turns into a calculated way to convey a social message or the hidden desires of the blushee.
