He turned with abruptness and started back the way they had come. But impulsively Billie ran to him, calling to him to stop. Yet when he did stop and turned to look at her she had not the slightest idea in the world what she had intended to say—if indeed she had really intended to say anything. “I—I just wanted to thank you,” she stammered, adding, with a swift little feeling of pity for this man who seemed so lonely: “And if there’s anything I can ever do to—to—help you——” “Who told you I needed help?” cried the man, his voice so harsh and threatening that Billie started back, half falling over a root. “Why—why,” faltered Billie, saying almost the first thing that came into her mind. “You looked so—so—sad——” “Sad,” the man repeated bitterly. “Yes, I have enough to make me sad.
