He was talking in English to his man, who had carried out his motor-coat. He was a prince—one of the wealthiest of all the German princes, a keen automobilist, a sportsman who had hunted big game in German East Africa, a landlord who owned a principality with half a dozen mediaeval castles and some of the finest estates in the German Empire, and one of the Kaiser’s most intimate relatives. And yet he was travelling with only his man and his motor-car.

Though Mary Jesup was heiress to the two millions sterling which her father had made during the past three years—as half the people in the hotel knew—yet she was aware that even her father’s wealth could not purchase for her the title of Princess of Hesse-Holstein.

She’s got them here, a long string twice round her neck and reaches to her waist. She’s wearing them to-day, and everybody, of course, thinks they’re false.”

“How foolish these American women are! Fancy wearing pearls of that price in the open street! Why, she might easily be robbed,” his master remarked.

“But who’d believe they’re genuine? They’re too big to take a thiefs fancy,” replied the faithful Charles. “The Jesups seem fond of jewellery. Miss Mary has a lovely diamond necklet—”
