“Because the man is insane. The doctor told me so just before he was taken away. You told me his losses in a moving picture deal had so turned his brain that he did more than you wanted him to when you first set him to spy on me. Well, his insanity is of a progressive form, and he is much worse now. He probably imagined that I was the cause of all his troubles, and so came to be revenged on me. I know you had nothing to do with it.”

“I am glad you are convinced of that,” said Mr. X. “And we have to thank you for treating us even better than, perhaps, we deserved. But from now on we will work in harmony.”

This promise was faithfully kept. Much to Ned Newton’s relief the sum of three millions was placed to the credit of the Swift concern the next day, and certain maturing notes were taken up. There was a goodly capital left, however, to start the manufacture of the talking-picture machines and they were soon put on the market, meeting with a big success. The radio and moving picture people, as well as several big theatrical interests, bought stock in the new company that was formed, and because of Tom’s invention, by means of which only authorized purchasers of his machine could view the broadcast scenes and listen to the music, there was no “bootlegging,” which meant that all the revenues would come to those entitled to them.

Tom was glad to learn, later, that Greenbaum’s insanity was not permanent, and that after the man was assured of a chance to make another fortune in the new business, his mind became calm and he was himself again. He was totally unaware of the outrages he had committed, though when told of them asked Tom’s forgiveness.

Snogg, Janner and Torpy were not heard of again, and the house on Rattlesnake Island, which was the property of the moving picture men, was made over to Tom as a sort of bonus. He and Ned spent many hours there, relaxing from their hard work.

It was after Greenbaum’s recovery, when certain things were recalled to him, that he explained what for a time had puzzled Ned and Tom. The man, who was an expert electrician, had found a means of neutralizing certain parts of the electrified fence. Hence he was able to get over, after the discovery of the planted bombs, to commit petty depredations that so annoyed Tom.

It was Greenbaum, also, who provided the fash melon that had thrown Koku off his guard. As Tom had guessed, the fruit was discovered in South America by a party of travelogue movie men who brought some back with them. Greenbaum, learning of Koku’s fondness for fash, used it to play what was nearly a fatal trick on the giant. Greenbaum had also been responsible for the “warning” Eradicate brought to Tom. That was just a bluff—intended to scare Tom, but it worked the other way.

The secret passage in the house on Rattlesnake Island was easily accounted for. The place had been built some years before to be used in making a certain moving picture, where a secret staircase played a part. Later the house was acquired by Mr. X and his colleagues to use as a prison and also as a meeting place for Tom.

Tom suitably rewarded Bill Tagg, the tramp, and that individual had his long ardent wish fulfilled. He rode in one of Tom’s aeroplanes and received the thrill of his life.

“Well, everything came out all right, didn’t it?” asked Ned of his chum as they sat in the house on Rattlesnake Island one evening after a successful day’s fishing. “Your talking pictures are making a hit.”
