"Look, boys! What do you think of that?"

He pointed to one corner of the reading-room, where two persons sat on a leather couch, one with a newspaper in his hand.

"Why, it's Link Merwell!" gasped Phil. "Merwell as sure as you're born!"

"How did that rascal get here?" murmured Roger.

"Who is it?" asked Bert, curiously.

"That fellow who is on the couch with Haskers," whispered Dave. "He used to go to school with us at Oak Hall, and then he had to leave, and after that he and a fellow named Jasniff robbed Mr. Wadsworth's jewelry works."

"Oh, yes, Roger told me about that. You fellows followed the rascals to Cave Island, didn't you?"

"Yes, and we caught Jasniff, but Merwell got away."

"Then why not have him locked up right now?" demanded Bert.

"It's what we ought to do," declared Phil.
