The Diva's Ruby by F. Marion Crawford

Logotheti reached his lodgings in St. James's Place at six o'clock in the evening of the day on which he had promised to dine with Van Torp, and the latter's note of excuse was given to him at once. He read it, looked out of the window, glanced at it again, and threw it into the waste-paper basket without another thought. He did not care in the least about dining with the American millionaire. In fact, he had looked forward to it rather as a bore than a pleasure. He saw on his table, with his letters, a flat and almost square parcel, which the addressed label told him contained the Archaeological Report of the Egyptian Exploration Fund, and he had heard that the new number would contain an account of a papyrus recently discovered at Oxyrrhynchus, on which some new fragments of Pindar had been found.

No dinner that could be devised, and no company that could be asked to meet him at it, could be half as delightful as that to the man who so deeply loved the ancient literature of his country, and he made up his mind at once that he would not even take the trouble to go to a club, but would have a bird and a salad in his rooms.
