Bractwo by John Grisham

Three disgraced former judges in a minimum-security federal prison run a lucrative scam, posing as young men who write intimate letters to closeted, high-profile clients and then extort payments; the scheme draws the attention of a manipulative outside operator who uses the operation to hide and funnel illicit funds, and the intertwined threads of blackmail, corruption and legal maneuvering escalate into a tense confrontation that exposes greed, hypocrisy and the vulnerabilities of powerful men.
