"What is it? No bad news of your father, I hope," her hostess asked, and the son, a fine type of the young Western citizen, noticed the dismay in Helen's face as she answered:

"Nothing has happened to my father. His partner has been badly hurt. I must return to-morrow, and, as it is a tiresome journey, if you will excuse me, I would rather not sit out the play."

The young man noticed that Helen seemed to shiver, while her voice was strained. He discreetly turned away his head, though he had seen sufficient to show him that certain lately-renewed hopes were vain.

"Miss Savine has not been used to gayety of late, and I warned her she must take it quietly, especially with that ride through the ranges before her. This place is unsufferably hot, and you can trust me to see her safe home, mother," he said.

Helen's grateful, "Thank you!" was reward enough, but it was in an unenviable humor that the young man returned to the theater when she sought refuge in her own room.

Solitude appeared a vital necessity, for at last Helen understood. Ever since Thurston first limped, footsore and hungry, into her life she had been alternately attracted and repelled by him. His steadfast patience and generosity had almost melted her at times, but from the beginning, circumstances had seemed to conspire against the man, shadowing him with suspicion, and forcing him into opposition to her will. Mrs. Savine's story had made his unswerving loyalty plain, and Helen had begun to see that she would with all confidence trust her life to him; but she was proud, and knowing how she had misjudged him, hesitated still. As long as a word or a smile could bring him to her feet she could postpone the day of reckoning at least until his task was finished, and thus allow him to prove his devotion to the uttermost test.

Now, however, fate had intervened, tearing away all disguise, and her eyes were opened. She knew that without him the future would be empty, and the revelation stirred every fiber of her being. Growing suddenly cold with a shock of fear she remembered that she had perhaps already lost him forever. It might be that another more solemn summons had preceded her own, and that she might call and Geoffrey Thurston would not hear! He had won his right to rest by work well done, but she—it now seemed that a lifetime would be too short to mourn him. Helen shivered at the thought, then she felt as if she were suffocating. Turning the light low, she flung the long window open. Beyond the electric glare of the city, with its shapeless pile of roofs and towering poles, the mountains rose, serenely majestic, in robes of awful purity. They were beckoning her she felt. The man whom she had learned to love too late lay among them, perhaps with the strong hands that had toiled for her folded in peace at last, and, living or dead, she must go to him. She remembered that the message said,—"Hire a capable woman in Vancouver," and it brought her a ray of comfort. If the time was not already past she would ask nothing better than to wait on him herself. Presently, when there was a hum of voices below, Helen, white of face but steady in nerves, descended to meet her hostess.

"I must go back to-morrow, and as it is a fatiguing journey you will not mind my retiring early," she said to excuse her absence from the supper party that was assembled after the play.

On reaching the railroad settlement Helen found the doctor in charge of Thurston willing to avail himself of her assistance. The physician had barely held his own in several encounters with her aunt, whom he suspected of endeavoring to administer unauthorized preparations to his patient, while on her part Mrs. Savine freely admitted that at her age she could not sit up all night forever. So Helen was installed, and it was midnight when she commenced her first watch.

"You will call me at once if the patient wakes complaining of any pain," said the surgeon. "Do I think he is out of danger? Well, he is very weak yet, my dear young lady, but if you will carry out my orders, I fancy we may hope for the best. But you must remember that a nurse's chief qualifications are presence of mind and a perfect serenity."
