The Firm; by John Grisham.

When a brand new graduate from a law school with excellent academic record receives an invitation from a small town law firm with an offer not only high but loaded with perks, should he suspect there is a catch, that not only the firm is involved in shady business but will go to any length to protect its secrets, including getting rid of those young associates that might wish to leave after discovering the truth?

How the protagonist triumphs over long odds is a study in extreme intelligence, and reading the book is far more superior, far more satisfactory in this respect.

The film is perhaps of necessity blanded down and instead of the intelligent last part invoving much detail it merely shows a handsome man running around. That may be satisfactory for the majority but if they are not given a chance to see the story as it was written, how would they know? Assuming a dumber audience for a film is as despicable as assuming a dumb, obedient readership for certain magazines for a large part of humanity.
