Read all about it over at the excellent blog of my amiga novelist and writing teacher, Leslie Pietrzyk, Work in Progress. I agree with her completely, that "The Great Gatsby is one of the most nearly perfect novels ever written." It's a novelist's novel.
P.S. I vaguely recall reading somewhere that someone from Alice Green de Iturbide's family married into the Fitzgerald family. Washington DC was a small world then. Both the Greens and the Fitzgeralds had a long history in the area.
