"It's Peters!" said Tom, in a hoarse whisper.
"Peters?" gasped Ned. "How could it be? His voice--"
"I know. It didn't sound a bit like Peters over the 'phone, but there's his picture, all right!"
Tom held up the plate. There, imprinted on it by the wonderful power of the young inventor's latest appliance, was the image of the rascally promoter. As plainly as in life he was shown, even to his silk hat and the flower in his button-hole. He was in a telephone booth--that much could be told from the photograph that had been transmitted over the wire, but which booth could not be said--they were nearly all alike.
"Peters!" gasped Ned. "I thought he was the fellow, Tom."
"Yes, I know. You were right, and I was wrong. But I did not recognize his voice. It was very hoarse. He must have a bad cold." Later this was learned to have been the case. "There's no time to lose," whispered Tom, while Mrs. Damon was doing her best to prolong the conversation in order to hold the man at the other end of the wire. "Ned, get central on the other telephone, and see where this call came from. Then we'll get there as fast as the airship will take us."
A second and temporary telephone line had been installed in the Damon home, and on this Ned was soon talking, while Tom, putting the photographic plate away for future use, rushed out to get his airship in shape for a quick flight. He had modified his plans. Instead of having a detective take a print of the photo telephone image, and make the arrest, Tom was going to try to capture Peters himself. He believed he could do it. One look at the wet plate was enough. He knew Peters, though it upset some of his theories to learn that it was the promoter who was responsible for Mr. Damon's disappearance.
The man at the other end of the wire was evidently getting impatient. Possibly he suspected some trick. "I've got to go now," he called to Mrs. Damon. "If I don't get those papers in the morning it will be the worse for Mr. Damon."
"Oh, I'll send you the papers," she said.
By this time Ned had gotten into communication with the manager of the central telephone exchange, and had learned the location of the instrument Peters was using. It was about a mile from the one near the sawmill.
