Through a long and tortuous path (following quotes in books...), I have stumbled across Antiphon's Tetralogies, of which this site seems to provide the most readable English version: https://www.sfu.ca/anewradermacher/x...tralogies.html

It's basically Mafia in ancient Greece. Each "tetralogy" is basically an accusation, a defense, a response to the defense, and a final defense, all in the context of a murder trial. I thought some mafia-inclined people could find it an interesting exercise.
