John Berendt's "Midnight in the Garden of Good and Evil" is much more famous... (& yes, it's wonderful!) ...but "City of Falling Angels" is my favorite. There are similarities between the two: the story of a modern day event, intertwined with a bit of history, a bit of gossip and quick, compelling word sketches of interesting locals; this time in Venice rather than Savannah.
“Keep a diary, but don’t just list all the things you did during the day. Pick one incident and write it up as a brief vignette. Give it colour, include quotes and dialogue, shape it like a story with a beginning, middle and end—as if it were a short story or an episode in a novel. It’s great practice. Do this while figuring out what you want to write a book about. The book may even emerge from within this running diary.” —John Berendt
