Don't worry about my system, I found it less intimidating to read a tiny section at a time, but people can respond in any way they feel comfortable.

I definitely see a family resemblance between Iris' narration and Laura's novel, and I assume it must be intentional, given that the clippings are so distinct.

Maybe the novel became famous because Iris uncovers it as a roman à clef? That's a guess, I haven't read beyond chapter two yet.
