“It is not true,” answered Grace evenly. “Remember, I am not here on my own choice, and I shall be pleased to leave now. You see I am perfectly able to go. If you detain me longer you will be punished. The war is at an end, or is supposed to be, and you have no right to keep me a prisoner. Are you going to permit me to go back to my own lines?” The German woman laughed harshly. “The Herr Officer will see you. We shall see,” was the non-committal reply. The Herr Officer came in a few moments later, the woman occupying the interval by a repetition of her questions of the previous day. The officer-doctor examined Grace or pretended to, then turned to the Frau. “Tell her she will die as the result of her getting up. She must not be permitted to go until we have the message. You have not heard?” he asked in German. The woman shook her head. “I will find out if anything has come since we spoke, and let you know. You will wait in the library.” He nodded, gave the Overton girl a frowning appraising glance, and turning on his heel strode out, followed by the woman, who locked the door behind her. Both were back in a few moments, rather to the girl’s surprise. “So?” said the woman nodding slowly. “It is Frau Gray?” Grace regarded her inquiringly. “What do you mean?” “That it is not Frau Schmidt, but Frau Gray.” “I did not tell you my name was Schmidt, for it is not. I am an American, not a Hun, nor do I admit that my name is Gray. The carrier pigeon was late in arriving this morning, eh?” Grace grinned broadly as she saw that the shot had gone home, for both showed their amazement. “Ah! I observe that the Herr Colonel understands English after all. A precious pair of enemy agents. What do you think will be done to you when my people find out about this--and about the pigeons?” “Nothing! They will never know,” retorted the woman savagely. “Do not be deceived. I have arranged that they shall, no matter whether I go back or do not go back.” She reasoned that no more pigeons would be used, now that the American army was nearing the river. Grace did not know that the army already had arrived. “It will not help your cause to detain me. It will have the opposite effect. Am I to go or stay?” continued Grace. “You are to--” An orderly rapped on the door and saluted as the colonel wheeled on him. “What is it?” demanded the officer. “Orders, Herr Colonel. The enemy has heard that a woman is being detained here. Unless she is released and given safe conduct to the bridge before twelve o’clock to-day they threaten to come and get her.” Grace understood every word of the conversation, but not so much as the flicker of an eyelash indicated that she did. She was not yet out of her difficulties and a slip, even in the face of that order, might prove her undoing. “What shall you do, Herr Colonel?” demanded the German woman. The colonel shrugged his shoulders. “They would not dare to do it,” added the Frau.
