Also, the Betrothed (1827) by Alessandro Manzoni, which is set during the 1600s plague. In a very famous chapter, one of the characters finds out he's got the plague, which is pretty close to what the GP describes.
How I was amazed by the pace and energy of 'Betrothed', not one boring minute in all of its 700+ pages. The translation by Bruce Penman available from Penguin is an exhilarating read.
