The downside to this is when they set a book where you live but it’s clear they’ve never lived there. This happens quite a bit with San Francisco - added for color by a writer who may have looked at a map and that’s about it.
I’ll never forget the murder-mystery book I read about a young military cadet couple that left their house in Forest Hill and went for a jog in Golden Gate Park and got attacked. Houses in Forest Hill are easily in the $5 million and up range, and even if these cadets happened to be the richest military personnel in history, there’s no way to get there easily without jogging a looong way down major commuter streets. If residents of Forest Hill wanted to go for a jog, I’d imagine they’d go to Lake Merced or along Great Highway, both of which would be a direct shot down Sloat Ave.
To the OP, White Palace was a good read for me, b/c it was set in my hometown of St. Louis and got the neighborhoods down pat. Not just the neighborhoods, but who would live there and how they would behave.
