Hit me over the head with a club . Grisham's worst book by far. 90% of the story is preaching to the reader that homeless people just have bad luck and are good guys. It would be ok if that was woven into a good story, but it is not. For great Grisham read The Firm and The Partner. For very good, read Runaway Jury and Pelican Brief. All of these are page turners. Street Lawyer is a stomache turner. Really bad. What happened
Output:
NEG
