"Good Lord!" Foster tugged at his hair until it stood upright.

"We can discuss the inventions at another time," announced the spinster, recovering from her astonishment. "I'll be upstairs, Kathleen, if you want me."

"Wait, I'm coming," but Foster turned on the threshold of the door, his curiosity mastering him. "There's just one question, Miss Kathleen; if you knew Karl von Mueller in Germany and, as you thought, met him here using the name of Charles Miller, why did you not at once conclude he was a German spy?"

"Because a year ago a school friend in Germany wrote me that Karl had disappeared after a duel, and she believed he was living in America under an assumed name," replied Kathleen, rising hurriedly. "Under those circumstances I thought it natural that he should have anglicized his name. Won't you stop—?"

"No, thanks," hastily. "I must see Kiametia. Good-night," and he disappeared into the hall. Miss Kiametia was talking to a white-capped nurse, who continued on her way upstairs on Foster's approach.

"Winslow has regained consciousness," announced Miss Kiametia, "and is sleeping naturally at last."

"I am delighted to hear it." Foster's tired face lighted with pleasure.
"Shall I tell Kathleen?"

"No, not just yet; good news will keep, and I think she is entitled to the happiness of being with the man she loves."

"Do you never crave for that happiness, Kiametia?" and there was a wistful tenderness in his voice which made the spinster blink suspiciously. Suddenly she slipped her hand in his.

"Suppose I say yes, for a change," she whispered, burying her head on his shoulder, and with a thankful heart Foster held her close as he whispered tender, soothing words in her ear.
