Both the men were somewhat taken aback by the girl’s sagacious grasp of the situation, and it came about that they began to obey her like subordinates.

She told her father to sally forth in search of a doctor, and he went. She gave Prince Aribert certain other orders, and he promptly executed them.

By the evening of the following day, everything was going smoothly. The doctor came and departed several times, and sent medicine, and seemed fairly optimistic as to the issue of the illness. An old woman had been induced to come in and cook and clean. Miss Spencer was kept out of sight on the attic floor, pending some decision as to what to do with her. And no one outside the house had asked any questions. The inhabitants of that particular street must have been accustomed to strange behaviour on the part of their neighbours, unaccountable appearances and disappearances, strange flittings and arrivals. This strong-minded and active trio—Racksole, Nella, and Prince Aribert—might have been the lawful and accustomed tenants of the house, for any outward evidence to the contrary.

On the afternoon of the third day Prince Eugen was distinctly and seriously worse. Nella had sat up with him the previous night and throughout the day.

Her father had spent the morning at the hotel, and Prince Aribert had kept watch. The two men were never absent from the house at the same time, and one of them always did duty as sentinel at night. On this afternoon Prince Aribert and Nella sat together in the patient’s bedroom. The doctor had just left. Theodore Racksole was downstairs reading the New York Herald. The Prince and Nella were near the window, which looked on to the back-garden.

It was a queer shabby little bedroom to shelter the august body of a European personage like Prince Eugen of Posen. Curiously enough, both Nella and her father, ardent democrats though they were, had been somehow impressed by the royalty and importance of the fever-stricken Prince—impressed as they had never been by Aribert. They had both felt that here, under their care, was a species of individuality quite new to them, and different from anything they had previously encountered. Even the gestures and tones of his delirium had an air of abrupt yet condescending command—an imposing mixture of suavity and haughtiness. As for Nella, she had been first struck by the beautiful ‘E’ over a crown on the sleeves of his linen, and by the signet ring on his pale, emaciated hand. After all, these trifling outward signs are at least as effective as others of deeper but less obtrusive significance. The Racksoles, too, duly marked the attitude of Prince Aribert to his nephew: it was at once paternal and reverential; it disclosed clearly that Prince Aribert continued, in spite of everything, to regard his nephew as his sovereign lord and master, as a being surrounded by a natural and inevitable pomp and awe. This attitude, at the beginning, seemed false and unreal to the Americans; it seemed to them to be assumed; but gradually they came to perceive that they were mistaken, and that though America might have cast out ‘the monarchial superstition’, nevertheless that ‘superstition’ had vigorously survived in another part of the world.

‘You and Mr Racksole have been extraordinarily kind to me,’ said Prince Aribert very quietly, after the two had sat some time in silence.

‘Why? How?’ she asked unaffectedly. ‘We are interested in this affair ourselves, you know. It began at our hotel—you mustn’t forget that, Prince.’

‘I don’t,’ he said. ‘I forget nothing. But I cannot help feeling that I have led you into a strange entanglement. Why should you and Mr Racksole be here—you who are supposed to be on a holiday!—hiding in a strange house in a foreign country, subject to all sorts of annoyances and all sorts of risks, simply because I am anxious to avoid scandal, to avoid any sort of talk, in connection with my misguided nephew? It is nothing to you that the Hereditary Prince of Posen should be liable to a public disgrace. What will it matter to you if the throne of Posen becomes the laughing-stock of Europe?’

‘I really don’t know, Prince,’ Nella smiled roguishly. ‘But we Americans have, a habit of going right through with anything we have begun.’
