We learn early on that the titular club refers to those lawyers who won't prosecute a case unless they're sure to win. The term was created (or at least first used publicly) by James Comey, indicating that such prosecutors have nothing to be proud of. Since it's the title of the book, you'd think that would be the answer to the question implied in the subtitle, but it's not. Or at least that's just part of the story.

There's a naive view of the law that if you break it and are caught, you pay the penalty. It was my naive view. It went along with this being a government of laws and not of men. In actuality, the law is just a tool in a complicated social and political matrix. You can be accused of being anti-business. You can hurt the stockholders or the employees but not the actual wrong-doers. And, you can be accused of hurting the wrong people potentially, and of hurting the economy. Etc.

Ultimately, the book tells the story of strong personalities (lawyers, judges, CEOs, politicians) battling each other while the actual legal case is just background.

Now you know. Should you read the book? Sure. Mr. Eisenger can tell a good story.
