At this moment the door was pushed open.  A tall man of distinguished appearance, still in the prime of life, and bearing a close resemblance to Bob, entered the room.  He glanced inquiringly at the boys.

“Something gone wrong?” he asked.  “What’s the trouble?”

“Hello, Dad.”

“Hello, Uncle George.”

It was Mr. Temple, Bob’s father and Frank’s guardian, and there was relief in the boys’ voices as they greeted him.  He always was so capable in an emergency.

“Motored home at noon today,” he said.  “Guess I’ve got spring fever.  Anyhow, I couldn’t stand it in the city.  Della told me you were over here and that you thought, perhaps, you would hear from the Hamptons today.”  Della was Bob’s younger sister, and the Temples’ only other child.

“We heard all right, Dad,” said Bob gravely.  Thereupon he proceeded to relate what had occurred.

Mr. Temple listened in silence.  His face showed he was disturbed.  At the conclusion of Bob’s recital, he walked over to a headpiece and put it on.

“No use, Uncle George,” said Frank, but Mr. Temple turned to him with a twinkle in his eye.

“That so?” he said.

With a cry, Frank leaped from his chair, seized a headpiece and put it on.

“Hurray, it’s Jack,” he shouted.  Then he bent over to the telephone and called: 

“Jack.  Jack.  Are you hurt?  What happened?”

“Oh, I’m bunged up a little,” came back Jack’s voice, in a cheerful tone.  “But there are no bones broken.”

“Was it the bandits?” demanded Bob, who had clamped on a third headpiece, as he elbowed Frank aside to speak into the transmitter.

“Yes.  Three of them,” responded Jack.  “A scouting party.  They sneaked in behind me.  Thought I was alone, I guess, but when I hollered for help Dad came in from the power house on the run and the pair of us put them down for the count.  We’ve got them tied up here now.  The microphone cord was snapped but I was able to make repairs.  So I started calling for you right away.”

“Jack, this is Mr. Temple,” cut in the older man at this point.  “If your father is there, please put him on the phone.  I’d like to speak to him.”

“All right, Mr. Temple,” answered Jack.  “He’s right here.  Wait just a minute.”

Frank and Bob politely removed their headpieces and walked to a bookcase, talking in low tones, as they leaned their elbows on the top of it.  This room, by the way, deserves a brief description.

It was circular and without windows.  The walls were hung with a material resembling burlap in appearance, but of special construction and sound-proof.  The ceiling was nine feet high.  From a point six feet up the walls material like that in the walls stretched to a point in the middle of the ceiling.  The room had somewhat the appearance of the interior of a small circus tent.  This construction was for the purpose of increasing the acoustic properties.
