"Yes," was her frank reply. "I am looking forward to the day when he can acknowledge me as his wife. Being an engineer he has a brilliant idea, namely, to perform a great service to my father in furthering his business aims, so that it will be impossible for him to denounce our marriage. Towards this end I am helping him. Ah! Mr Hebberdine, you don't know what a dear, good fellow Paul is." The young man sniffed suspiciously. "He has invented a new submarine boat which will revolutionise the naval warfare of the future. Father, in secret, builds submarine boats, you know. But Paul is anxious to ascertain what difference there is between those now secretly building and his own invention, prior to placing it before dear old dad." "Well?" She hesitated. "I wanted to ask you, Mr Hebberdine, if you will do me a favour to-night," she said presently. "Paul is staying at the `Star,' down in the village, in the name of Mr James. I dare not go there, and he dare not approach me. There have been thieves about in this neighbourhood lately, and dad is having the castle watched at night by detectives." At this Garrett pricked up his ears. Glenblair was, in those circumstances, no place for his Highness and his clerical companion. "I wonder," she suggested, "whether you would do me a great favour and go down to the village to-night about ten and--and give him this." From within her fur bolero she produced an envelope containing what seemed to be a little jewellery box about two inches long by an inch and a half broad. This she handed to him saying, "Give it into the hand of nobody except Paul personally. Tell him that you are my friend--and his." So devoted was the girl-wife to her husband, and so unhappy did she seem that Garrett, filled with the romance of the affair, at once agreed to carry out his promise. Her remarkable story had amazed him. He alone knew her secret. As they sat at dinner that night, her eyes met his once or twice, and the look they exchanged was full of meaning. He was the bearer of some secret message to her husband. At half-past nine when the men had gone to the billiard-room, Garrett slipped upstairs to his room to put on a pair of thick boots, for he had a walk through the snow a good couple of miles to the village. Scarcely had he closed the door when it opened again, and the Prince, his finger raised in silence, entered, and in a low excited whisper exclaimed: "It's all up! We must get away on the car as soon as possible. Every moment's delay means increased peril. How have you got on with Elfrida?" The chauffeur stared at him without uttering a word. "Elfrida!" he echoed at last. "Well, she's told me a most remarkable story, and made me her confidante." Then, as briefly as possible, he told him everything. How her husband was staying in Glenblair village as Mr James; and how he had promised to convey the little packet to him.
