These men are themselves our strongest witnesses; for they will be shown never to have brought suit against Demaretus in his lifetime; but, more than that, anyone who examines and studies the case itself will see, not only that he did not receive the money, but that it was impossible that he should have received it. For the debt was in Bosporus, a place which Demaretus never visited; how, then, could he have collected it? Ah, but, they will say, he sent someone to get the money.
