"And this time he doesn't get away from us!" cried Paul, as he darted toward the mysterious stranger.


CHAPTER XXI

A CHASE

The unknown interloper pursued his usual tactics. That is, he turned and fled as soon as he saw Paul coming toward him. And he went surprisingly fast for a lame man. Alice was the first to notice this.

"Look!" she cried. "That man limps hardly at all now."

"That's so," agreed Ruth. "Perhaps he only did that as a disguise."

"Excuse me!" called Russ. "I've got to get in on this chase," and he left the two girls, and ran after Paul, who had started ahead of him.

"Oh, please be careful!" cried Ruth, nervously.
