Zélie couldn't rest in Albuquerque after that. She went east, and would quietly have slipped away after Garth to Europe as a Red Cross nurse if she hadn't been afraid he would suspect why she followed. Instead, she stopped in New York, and got work as a stenographer with a firm of engineers, thanks to an introduction from Jack. When America flung herself into the war-furnace too, Zélie Marks did train as a nurse: but in little more than a year came the Armistice, and the girl reluctantly took up her old profession again. Now, she loved Major Garth, V.C., a hundred times more than she had loved Jack Garth, the smart young inventor. Yet here she was on the way to Arizona, where she had promised to go and get his house (that house she had once thought might be hers!) ready to receive another woman! When he had come to her flat early in the morning and told her what he wanted done to "surprise Marise," she had made him some hot coffee, and agreed to everything. "Yes, Jack," she said, "I'll do it, and your wife shall never know, unless you tell her yourself. And I advise you not to do that, because if you drop the least hint, she'll hate the house and me, and be angry with you. Any girl _would_! I'm not blaming her. She shall think that your house was just waiting, in apple-pie order, her room and all: or else--yes, _that_ would be best!--she shall think Mothereen did the whole business. Of course, that's what you'd want Mothereen to do, and what she'd want to do, if she were strong enough for the task. But as it is, she shall work just enough, so that she won't have to _fib_--no hard work to tire her out. She'll love to go to the Canyon with me--the dear Mothereen!--and she'll have the time of her life." So that was Zélie Marks' secret errand. She was to travel straight through to Kansas City, by the Santa Fé "Limited." There she was to pause in her journey and purchase a list of things which had never been supplied for Garth's new house, finished only a short time before the war: beautiful silver, crystal and fine linen, and the decorations for a room worthy of a bride like Marise. Kansas City was a big enough town to provide these things, Garth thought; and as it was many hours nearer the Grand Canyon than was Chicago, Zélie's purchases would reach their destination sooner than if she shopped there. Garth had to leave much to Zélie's taste, but his advice, "Try to think what _she_ would like," had hurt. Zélie was to have all the trouble and pain, yet must strive to please Marise Sorel, not herself. And poor old Zélie was never to get any credit for the sacrifice!
