“Well, we’ll do the best we can,” said Tom, grimly.  “Now I’m going to get a warrant for the arrest of Peters, and one for Boylan, and I’m going to get myself appointed a special officer with power to serve them.  We’ve got our work cut out for us, Ned.”

“Well, I’m with you to the end.”

“I know you are!” cried Tom.

CHAPTER XXIV

THE LONELY HOUSE

The young inventor had little difficulty in getting the warrants he sought.  In the case of Boylan, who seemed to be Peters’s right-hand man, when it came to criminal work, Tom made a charge of unlawfully taking the airship.  This would be enough to hold the man on until other evidence could be obtained against him.

As for Peters, he was accused of taking certain valuable bonds and stocks belonging to Mr. Damon.  Mrs. Damon gave the necessary evidence in this case, and the authorities were told that later, when Peters should have been arrested, other evidence so skillfully gotten by Tom’s photo telephone, would be brought before the court.

“It’s a new way of convicting a man—­by a photo telephone—­but I guess it’s a good one,” said the judge who signed the warrants.

“Well, now that we’ve got what we want, the next thing to do is to get the men—­Peters, and the others,” said Tom, as he and Ned sat in Tom’s library after several hours of strenuous work.

“How are you going to start?” the young banker wanted to know.  “It seems a strange thing that a man like Mr. Damon could be made away with, and kept in hiding so long without something being heard of him.  I’m afraid, Tom, that something must have happened to him.”

“I think so too, Ned.  Nothing serious, though,” Tom added, quickly, as he saw the look of alarm on his chum’s face.  “I think Mr. Damon at first went away of his own accord.”

“Of his own accord?”

“Yes.  I think Peters induced him to go with him, on the pretense that he could recover his fortune.  After getting Mr. Damon in their power they kept him, probably to get the rest of his fortune away from him.”

“But you stopped that, Tom,” said Ned, proud of his chum’s abilities.

“Well, I hope so,” admitted the young inventor.  “But I’ve still got plenty to do.”

“Have you a starting point?”

“For one thing,” Tom answered, “I’m going to have Mrs. Damon mail a fake package to the address Peters gave.  If he, or any of his men, call for it, we’ll have a detective on the watch, and arrest them.”

“Good!”

“Of course it may not work,” spoke Tom; “but it’s something to try, and we can’t miss any chances.”

Accordingly, the next day, a package containing only blank paper, made up to represent the documents demanded by Peters as the price of releasing Mr. Damon, was mailed to the address Mrs. Damon had received over the wire from the rascally promoter.  Then a private detective was engaged to be on the watch, to take into custody whoever called for the bundle.  Tom, though, had not much hope of anything coming of this, as it was evident that Peters had taken the alarm, and left.
