"Why, certainly," was the reply, and the German named an address and gave the necessary directions for getting there. "I don't imagine," he added, "you will find her home much before 12 o'clock, the café does not close until eleven." Lord Hastings thanked the man and the latter took himself off. "Well, we have that much to go on, anyhow," said Lord Hastings. "Now the best thing for us to do is to go to Mlle. Dulcé's home and await her arrival." "And maybe they won't let us in," said Jack. "We'll have to chance that." An hour later they sought the address given and mounted the steps. Lord Hastings rang the bell. A pleasant-appearing woman of middle age answered their summons. At a glance Lord Hastings knew she was French and he addressed her in that language. "Could it be that you are Madame Dulcé?" he inquired courteously. The woman smiled as she answered in the affirmative. "We," said Lord Hastings, indicating Frank and Jack as well as himself, "would have a few words with your daughter Marie when she returns home. We have sought her here rather than at the café for several reasons." A look of deep anxiety spread itself over Madame Dulcé's face and she asked excitedly: "What has she done, sir? Surely she will not be arrested? You do not take her for a spy?" "You need have no fear," returned Lord Hastings reassuringly. "We mean no harm. May we come in and wait?" "Certainly." Madame Dulcé led the way into a small, though cozy parlor and took their hats and coats. "Marie will be here soon after twelve," she said. "She always comes straight home, for she knows I worry about her." "How does it happen that she sings in the café?" asked Lord Hastings. "Because we are so poor," was the reply. "Her salary there enables us to keep the wolf away from the door. Frau Heffler, who also sings, was the one who so kindly gave her the opportunity." "I see," said Lord Hastings, and became silent. The time passed slowly; but it passed. Frank waited eagerly, for he was anxious to see the girl again. Jack noticed the look on his chum's face and remarked: "Now just be patient. Marie will soon be here." Frank smiled. "It's not as bad as that, I assure you," he returned. Came the sound of light footsteps without. A key turned in the front door and the footsteps came toward the parlor. "You have company, mother?" asked the girl's voice as she tripped forward. "Some gentlemen to see you, Marie," was the reply. In the doorway the girl stood spellbound for a brief instant, as she made out the faces of the callers. At first she did not recognize Lord Hastings and Jack, but she knew Frank instantly. "Lieutenant Chadwick!" she exclaimed. She came forward with outstretched hand and again Frank bent low over it. "But tell me," she said. "How were you able to find my home? And what is it you want of me?" "I found your home by asking," returned Frank. "As for what we want, I would first present my commander and brother officer to you."
