Trumble is a minimum-security federal prison, home to drug dealers, bank robbers, swindlers, embezzlers, tax evaders, and three former judges who call themselves The Brethren. They meet each day in the law library where they spend hours writing letters. They are fine-tuning a mail scam, and its starting to pay big. They money is pouring in.

Then their little scam goes awry. It ensnares the wrong victim, a powerful man on the outside, a man with dangerous friends, and The Brethren’s says of quietly marking thine are over.
