Quotation from JD Salinger in Short Story

A break from science for a minute......

My other love in life is literature. I'm reading Nine Short Stories by JD Salinger. Here is a quotation I'd like to share:

"This is the squalid, or moving part of the story, and the scene changes. The people change, too. I'm still around, but from here on in, for reasons I'm not at liberty to disclose, I've disguised myself so cunningly that even the cleverest reader will fail to recognize me."

He turns out to be the main character of the second half. But you don't figure it out until near the end. Genius.
