He raised a warning hand, for his ears had caught the sound of light footfalls in the hall. "Mother's coming back," he said abruptly. "Don't say anything to her of my cable to Gillie." And at once, without any change in his voice, he went on: "There's a great deal that would interest you, quite as much as Godfrey, out there----" The door opened, and he turned round quickly. "I'm trying to persuade Laura to come out to Mexico," he exclaimed. "Godfrey has practically promised to pay me a visit, and I don't see why she shouldn't come too!" Mrs. Tropenell made no answer.

Slowly, feeling as if she had suddenly become very, very old, Mrs. Tropenell dropped the curtain, and walking back to her usual place, her usual chair, took up her knitting. CHAPTER IV Laura and Oliver Tropenell walked across the grass in silence, and still in silence they passed through under the great dark arch formed by the beech trees. Laura was
