On finding the true narrative of events (or some such thing)

Bleeding Edge, Thomas Pynchon, page 322:

...Maxine recalls that Heidi has a collection of decorated dollar bills, which she regards as the public toilet wall of the U.S. monetary system, carrying jokes, insults, slogans, phone numbers, George Washington in blackface, strange hats, Afros and dreadlocks and Marge Simpson hair, lit joints in his mouths, and speech-balloon remarks ranging from witty to stupid. 

"No matter how the official narrative of [Sept. 11, 2001] turns out, it seemed to Heidi, "these are the places we should be looking, not in newspapers or television but at the margins, graffiti, uncontrolled utterances, bad dreamers who sleep in public and scream in their sleep."
