My theory was that the Romans would be having a Senate meeting, concerning the Greeks and what to do with them. Then something would happen to cause confusion, and in all the chaos, one of the Senators was assassinated, and the Greeks were held responsible. Although that would be a tad violent for a Rick Riordan book.
