Rulers of Kings by Gertrude Atherton

After that Fessenden took his tea -- he detested tea -- every day in the Hungarian house. Sometimes the entire court was present, all conforming to the English custom approved by their princess, except the Obersthofmeisterin, who consumed glass after glass of iced coffee, to the secret envy of the rest. Sometimes only the younger ladies-in-waiting were present besides the Archduchess and Alexandra; but even at dinner, to which he was frequently invited, Fessenden rarely had a word alone with Ranata. Twice he had ridden with the court to the summit of the Schwabenberg in the early morning, but he had been obliged to content himself with observing the fine effect of flaming hair among the sweeping branches of the acacia.

If Fessenden had not long since come to the conclusion that it was a waste of man's valuable time to puzzle over the idiosyncrasies of any woman, he would have wondered at the sudden change in the Archduchess's tactics. She had dropped coquetry as abruptly as she had assumed it, and now treated him with a sisterly frankness which, in some respects, was a curious imitation of Alexandra's. The truth was that Ranata had taken warning from an angry glint in her friend's eye, although the subject of Fessenden had been mutually avoided. Moreover, Ranata had informed herself that the American's friendship would doubtless be as valuable to the House of Hapsburg as his love, and far easier for her inexperienced self to manage.
