I found a whole bunch of articles on JSTOR that I am interested in reading.
I put in:
fictional
rhetorical
triangle
In case I have some time and want to go back and read them. On mysteries (another favorite genre) and fiction footnotes and secrecy in fiction (dealing with Hawthorne). Also, the experience of Cinderella and writing histories, which always interests me just for fun.
Most of these sources are old.
