Don't know where to find it, but I read another such mystery involving the same real life detective, that involved a girl who when into a motel, and never came out. I'm sure someone will know what I'm referring to.
You answered yourself. Read View is great even with well-behaved sites, use it generously.
Edit: I retract my comment, Reader View shows about the last third of the article, and I had already blocked JavaScript there in a previous interaction. Vanity Fair sucks.
It's the first case I've seen where Reader View shows incomplete content, and I use it almost daily because it makes long reads very comfortable. It might be that Reader View sucks, but I'm more inclined to blame Vanity Fair in this case.
I find Ctrl-A, Ctrl-C, followed by a visit to my favorite text editor often works like a champ -- even when scrolling is disabled and only a paragraph or two is visible.
