“Oh, well,” Barney saw how disappointed the three chums were, although they admitted the justice of the official’s attitude, “let’s go out and see my old patron and comrade.”

The Chief of Police agreed to look into the charges Griff had made and turned his car to return to his home, while Barney, in one cab with Bob and Al, and Mr. Parsons in the one they had called, with Curt and his own son, went on.

There was a vociferous greeting between Mr. Tredway and his plant manager.

“Why didn’t you tell me you were all right?” he cried, pumping the plant owner’s hand, slapping his back, and, as Al said later, “almost kissing him,” while the mysterious stranger, and the others watched with various feelings.

“I had to make my plans in secret,” Mr. Tredway retorted. “Not even my partner knew until tonight. But—let us get acquainted, all the way ’round.”

He turned to the mystery man behind him.

“This is my brother,” he presented the man, “and so these are the three young men who have worked so hard to solve the mystery of my crash into the lake!” He shook hands and they selected a private dining room on the second floor for a midnight repast.

“Well,” he said, smiling pleasantly at the three rather silent youths as the first course, a hot, nourishing soup, was served, “have you solved the puzzle of the mystery crash?”

“I think we have—but not all, sir,” replied Bob. “I think I can put together what happened, but not why it had to happen.”

“Go ahead,” Mr. Tredway encouraged.
