Harper Lee's To Kill a Mockingbird.
-
Genius book.
-
Now, who'd like to get out of the first pop quiz?
-
I'm shocked.
-
Alright. You can skip the quiz
-
if you tell me which author invented the paperback book.
-
Anyone?
-
He was British.
-
He also invented the serial.
-
In fact, at the end of the third chapter of his first novel
-
he had a man hanging from a cliff by his fingernails.
-
Hence, the term cliffhanger.
