note in a book

just found this typewritten paragraph taped inside the front cover of a copy of Pynchon's Crying of Lot 49:

this is a good novel for directors of plays to read and re-read because the action is essentialy non-verbal and because play directors must look beneath the honest surfaces of events to see what really went on. As you read this, try to block it's action in your mind and characterize the characters, merely as a strange kind of paper chase.

I guess that's one way to approach it...
