Is There a Librarian in the House?

People don't become librarians for the fame, fortune or excitement, but there's a little Walter Mitty in all of us...
Marian the Librarian is flying to a librarian convention, nodding off in her middle seat, which she has thoughtfully not tipped back to avoid annoying the passengers behind her, and trying not to snore or drool or touch either arm rest lest she infringe on her seatmates' personal space, she hears the P.A. announcement,
"Is there a librarian on board? we have a slight emergency in Business Class requiring immediate biblio assistance."
Marian jerks awake instantly, eye's pop open, she nods apologetically to the passenger in the aisle seat and indicates she needs to get by. Grabbing her bookbag from under the seat, she hurries up the aisle to the Flight Attendant and whispers,
"I'm a librarian. How can I help?"
"There's a passenger in extreme distress, hyperventilating over a book he's reading and looking pale and clammy, almost like he's in shock," the FA explains as she leads Marion through Business Class to a seat where, indeed, a male passenger, middle-aged, well-dressed, is breathing unevenly with his hands gripping the latest Dan Brown best seller tightly.
"Oh dear, that's the third case I've seen this week. Deadly Prose Syndrome with Implausable Plot Complications. We have to act quickly."
Marian carefully pries the stricken man's fingers from the Lost Symbol and places it in a sick bag for disposal.
"I'm afraid the only treatment for this patron, er patient, is an immediate infusion of The Classics or failing that, any book with sufficient character development, three-syllable words and dependent clauses to act as an antidote. I think this will work."
Marian riffles through her black bag and pulls out Hawthorne's The Scarlet Letter, and places it gently in the man's hands.
"That should do it. I may have to read it aloud to him at first but then his ability to read on his own should kick in and he'll be right as rain."
