She would have risen and turned up the gas, only that she was ashamed to do so. The fire was blazing merrily, shedding a ruddy light upon the homely room, the most commonplace room in the world. There was Captain Grey sitting there smoking—just an ordinary young man come to visit his sister. There was herself—just Lexy Moran, well fed and warm and comfortable, with more than a hundred dollars in a bag round her neck. She could hear Mrs. Royce moving about in the kitchen, humming to herself in a low drone.

“I will not be silly!” she told herself.

And just then a train whistled—a long, melancholy shriek. Lexy had a sudden vision of it, rushing through the dark and the rain. She had a sudden realization of the outside world, vast, lonely, terrible, stretching from pole to pole—forests, and plains, and oceans. The monstrous folly of pretending that everything was snug and warm and cozy! Things did happen—only cowards denied that.

“Captain Grey!” she cried abruptly. “What you’ve told me—it is queer; and it’s even queerer when I think what has brought me here to this little place. Both of us here, in Wyngate! I think I’ll tell you.”

“I’ll try to help you,” he said simply.

“Oh, thank you!” cried Lexy, with a rush of gratitude. She wanted some one to help her, and she could imagine no one better for the purpose than this young man. He would help her—she was sure of it. Even the fact of having told him most wonderfully lightened her burden. She gave an irrepressible little giggle.

“We have almost all the ingredients for a first-class mystery story,” she said; “ex[Pg 330]cept the jewel—the famous ruby, or the great diamond.”

“It’s an emerald, in this case,” said Captain Grey.
