The point of this blog, though, is not his character, but his advice-about-structure. For a 600 page novel, his outline is 100-150 pages. He talked about filling the frame. He loves detail of every kind. It's well-organized bricolage, if you ask me. Way beyond many of us at Hamline who suggest back-story for characters -- favorite clothes, CDs, etc.
JE's outline might look like this for an opening scene-- "X watches TV where Kennedy's funeral is being telecast. X is just out of bed. He's in pajamas and one slipper. He's smoking filtered Camels and coughing. This scene begins the theme of death and public recognition. Or lack thereof. The hotel room is mid-range. Anonymous. The door to the mini-bar is open. Fast food wrappers from Wendy's on the desk." And so on.
I'm the sort who doesn't want to know where he is going in a book (even if that's a trick I play on myself). JE claims that all that detail frees him up to get to the heart of the scene when he writes it. For me, it would get in my way. I like to discover as I move the story on (horizontal); JE likes to discover vertically.
There's something in this extreme-sounding advice that it like, however. If someone wants to try it, I'd go as far as Ellroy himself. Very, very detailed. I'd add specifics from every sense -- touch, smell, taste, hearing, sight. The latter being least important. Everybody does sight. Few do taste.
If someone writes short books like mine, assume a draft of 150 pages. That'd make the outline 30 or so. Maybe a little less. I can see the outline turning into the/a book. And that wouldn't be a bad thing either.
