"Yes, Marta, no doubt," he admitted; "but no more than they would have lost in the end. It is only the mounting up of their casualties that can end the war. Thus the lesson must be taught."

"And I can be of most help when the attack on the main defence is begun?"

"Yes."

"And when Westerling finds that my information is false about Engadir—then—"

She had never put the question to him in this way before. What would Westerling do if he found her out?

"My God, Marta!" he exclaimed. "If I'd had any sense I would have thought of that in the beginning and torn out the 'phone! I've been mad, mad with the one thought of the nation—inhuman in my greedy patriotism. I will not let you go any further!"

It was a new thing for her to be rallying him; yet this she did as the strange effect of his protest on the abnormal sensibilities that her acting had developed.

"Thinking of me—little me!" she called back. "Of one person's comfort when hundreds of thousands of other women are in terror; when the destiny of millions is at stake! Lanny, you are in a blue funk!" and she was laughing forcedly and hectically. "I'm going on—going on like one in a trance who can't stop if he would. It's all right, Lanny. I undertook the task myself. I must see it through!"

"No matter what they do to me or what becomes of me!" she thought. "I'm a lost soul, anyway. The thing is to serve as long as I can—and then I don't care!"
