What can you get from Flavius, if Flavius owes you nothing? Moreover, why does he now enter into a mutual engagement about a sum which he has already exacted some time ago? But what can Flavius be going to give you, if he has already paid Roscius everything that he owed? Why is this new mutual arrangement interposed in so old an affair, in a matter so entirely settled, in a partnership which has been dissolved? Who is the drawer up of this agreement? who is the witness? who is the arbitrator? who? You, O Piso: for you begged Quintus Roscius to give Fannius fifteen thousand sesterces, for his care, for his labour, for having been his agent, and for having given security, on this condition, that, if he get anything from Flavius, he should give half of that sum to Roscius. Does not that agreement seem to show you with sufficient clearness that Roscius settled the affair on his own behalf alone?
