"Perhaps Dick is at our house waiting for us to come back," put in Frank. "Let us go home and see. We can come back early in the morning." He looked at his watch. "Do you know that it is after two o'clock? I'm afraid my father will worry about me."

They talked the matter over and decided to return to Frank's home without further delay.

It was a silent trio that walked the streets, which were now practically deserted. Tom and Sam were much worried and Frank hardly less so, for the senator's son and Dick had been warm friends for years.

When they reached the mansion they found Senator Harrington pacing the library nervously.

"Well, here you are at last!" he cried. "I was wondering what had become of you."

He listened to their tale with close attention.

"No, Dick has not come in," he said, "at least, I think not.
Run up to the bedrooms, Frank, and see."

Frank did as requested, and soon returned.

"No, he isn't about," he said disappointedly,

"It's mighty queer what became of him."
