There are a lot of movies based on Grisham books. I decided to check some out when I found about them. Never watched this movie but kept hearing about it, so I had it my tbr pile ready for the game square.
The idea is that in a country filled with lawyers to the gills (it's a factor that's gone over a lot through the pages), a shot in a million had a lot of chances of happening: some busy-body would stumble into the right theory. The bad luck comes in when the brief is picked up as a way to needle back in a quarrel between agencies. No one takes it seriously, but a lot of noise is made. And it just happens to be right. A lot of pettiness that results in a murder fest.
It's an entertaining thriller (and depressing if you have your brain-cells firing too much). I'm still likely to read The Firm at some point (the movie that first got me interested in these books)
