ng our affair further than he desired. I he heard from a certain person who is in the habit of giving me veracious news that Lord Robert had sent to pon his wife. Certainly all the Queen has done with us and with the Swede, and will do with all the rest in the matter of her marriage, is only to keep Lord Robert’s enemies and the country engaged with words, until this wicked deed of killing his wife is consummated. I am told some extraordinary things about this intimacy which I would never he believed, only that now I find Lord Robert’s enemies in the Council no secret of their evil opinion of it.” The Queen tried to face the Bishop with her usual blandishments, but his eyes were opened, and when he pressed the point closely, she became coolly dignified, surprised that she had been misunderstood, and threw over Lady Sidney and Dudley, who reciprocally cast the blame upon each other. The Bishop and the Emperor’s ambassador were furious; and, as the best way to checkmate46 Dudley, approached the Duke of Norfolk, who had been declaiming for some time against the insolence of the rising f
