"If it was only a few minutes ago, he hasn't had time to get far," her father was saying with a grim light in his eyes.

Billie could stand the suspense no longer, and she rushed forward, grasping her father's arm. The earnest conversation between the guard and Mr. Bradley and their evident excitement had already attracted the attention of the line of people, and now they watched Billie curiously.

"Daddy, what do you mean?" Billie cried in a voice tense with excitement. "Is the trunk safe? Have you found it?"

"Yes. But only to lose it again," said her father, and then went on hurriedly to explain. "The guard says he saw a trunk here only a little while ago that answers our description, but now it's gone. He remembers seeing a suspicious looking man hanging around, and it's barely possible that the man may have stolen it. He also remembers seeing this fellow drive off in a Ford car just a few minutes ago."

"O-oh!" cried Billie incredulously. "The trunk has been stolen!" Then she whirled around and faced the guard. "Are you sure it was our trunk? Could you describe it?"

"Yes," the guard answered, excited himself by this time. "I took special notice of it because it was so odd and shabby."

"That trunk was worth five thousand dollars!" wailed Billie, thereby causing another ripple of surprise among the onlookers. Then she turned pleadingly to her father.

"Daddy, we must find the trunk, we must!" she cried. "Just think what it means." She was on the verge of tears, and her father came suddenly to a decision. He turned quickly to the guard.

"Is it possible to get a machine around here—a fast one?" he asked.

"I don't know. But here's the man who keeps the livery stable."
