Sounds like a real peach of a book. BTW, Cassius wasn’t related to Crassus. After his defeat by Antony, he killed himself (ahem) with help from someone who beheaded him, so, probably not actually a suicide. The wikiwacky page states he was buried on Thasos, but that’s a modern myth based on some alleged historian who claimed to see his grave relics in a museum there. Needless to say, they’re not there, and probably neither is his grave.
AFAIK, *none* of the murderers of Julius Caesar have known graves (which isn’t too unusual for the famous of ancient times), whereas the spot in Rome where Caesar was cremated by the grieving Roman public can still be visited, and you’ll find fresh flowers there if you go.

I never suggested Cassius was any relative of Crassus. He was an officer in Crassus’ army, as was Crassus’ son who also died in the fight.
I don’t remember the authors of this history series, but the book is put away somewhere because I had an idea of creating a play about this. If I ever do it, the plot is modern actors are rehearsing Julius Caesar, and the actor play Cassius decides to research why Cassius was so motivated to kill Caesar. The actors then decide to tell this story written in the styled of Shakespeare, to produce for modern audiences. I also includes a modern warning about the hubris of thinking fighting in that region is such a great idea.
