John Grisham's The Rainmaker: Describe the character Deck.

The most fully developed supporting player is Deck Shifflet. Unable to pass the bar, he terms himself a "paralawyer" and chases cases on Bruiser Stone's behalf. A divorced compulsive gambler with a nervous tic and a generally unhealthy appearance, Deck operates on the grimy fringes of the legal profession and seems willing to dabble in Stone's illegal activities. His friendship with Rudy attests to Rudy's tolerance and gregariousness. Rudy and the Black case could give Deck a financial windfall and the accompanying respectability; his pathetic career consists of attempts to latch onto a real lawyer so that he can share in the wealth and glory of a big case.
