`` The herald has not yet returned from Cambrai , my lord , '' said De Vergy , who stood near by . `` He is expected between the hours of five and six this evening . '' `` Leave the letter , my lord , '' said Charles , `` and send Byron to me when he arrives . I shall be here at six o'clock to give him full instructions . '' The letter was deposited in a small iron box on the table , and the duke left the room , followed closely by the lords and pages . Yolanda and her stepmother remained on the divan in silence for fully an hour after the duke had left . The duchess was first to speak .
