Clementina by A.E.W. Mason

The next morning Wogan was tossing from side to side in a high fever. The fever itself was of no great importance, but it had consequences of a world-wide influence, for it left Wogan weak and tied to his bed; so that it was Gaydon who travelled to Rome and obtained the Pope's passport. Gaydon consequently saw what otherwise Wogan would have seen; and Gaydon, the cautious, prudent Gaydon, was careful to avoid making an inopportune discovery, whereas Wogan would never have rested until he had made it.

Gaydon stayed in Rome a week, lying snug and close in a lodging only one street removed from that house upon the Tiber where his King lived. Secrets had a way of leaking out, and Gaydon was determined that this one should not through any inattention of his. He therefore never went abroad until dark, and even then kept aloof from the house which overlooked the Tiber. His business he conducted through his servant, sending him to and fro between Edgar, the secretary, and himself. One audience of his King alone he asked, and that was to be granted him on the day of his departure from Rome.
