The "Stella" mentioned by the brothers, though the aviator's wife and evidently the mother of the "kiddies," was plainly not beloved. Either the couple were legally separated, or their married life was a farce. Only on that single occasion had Sanderson mentioned the woman—and never to his nurse.

The discovery had halted instantly any advance Belinda might have contemplated toward a closer friendship with the aviator. There had already been intimate moments between them when youth had called strongly to romance—when each had lifted for a little the veil which hid those secret lives we all live.

Belinda had thought she saw what lay behind Frank Sanderson's reckless bearing and volatile spirits—and approved. There were deeper currents in the aviator's soul than the shallows he showed to the world in general. She felt that he had a far more serious reason for taking up the perilous work of aviation than he was willing ordinarily to admit.

On the other hand, she had hinted at some portion of her doubts and uncertainties for the future in her disclosures to Sanderson. He did not understand entirely what she meant; had he done so he would never have hastened away from the hospital, accepting the night nurse's observations for facts, and leaving only the flowers and the book as a reminder of his friendly intercourse with Belinda.

When the girl bade the matron and her particular friends among the nursing staff good-by that last evening and left the hospital by the side exit with her bag, it was her fate to meet Doctor Herschall likewise going out. Or had he waited for her?

"We lose you, do we, Miss Belinda?" he said, taking her bag with his usual assurance. "We shall miss you—none more than I, Fräulein, I do assure you."

"You are very kind, Doctor," murmured the girl, wishing that she might rid herself of him.

But she had no inspiration for his dismissal. His way could not possibly lie in the direction of her home, yet he took that turning as a matter of course.

She could not afterwards have repeated their desultory conversation, even in part. She was confused and nervous—as she always was in the surgeon's company.

"I shall do myself the honor of calling upon you and your good aunt, Fräulein," declared he, "and at an early date."
