So the detective reached the conclusion that Kester was, in all probability, communicating with his relatives. It was evident that he was not writing home. Too close a watch could be kept on letters coming to a small town for any of his people or their confidential friends to be receiving them without the knowledge of the special agents who, through the postmaster and letter carriers, had been steadily watching this means of communication.

So the conclusion was reached that Kester was getting messages to his people through some other means than the mails, in all probability through a confidential messenger. To do this he must be near by. He could hide to best advantage in a city. Philadelphia, Pittsburgh, Baltimore were in a convenient radius. The detective drew the conclusion that, were he in the boots of the fugitive, he would have taken refuge in one of these cities; that, had he not been willing to risk the mails, which Kester evidently was not, he would have used some trusty go-between and through that agency would have learned the news from home and received from his relatives the money upon which to live.

Upon the basis of this theory Billy Gard asked himself more questions.

"Were I hiding under such conditions whom would I use as a messenger?"

A faithful former servant who might be living there, a distant relative, some individual hired for the task. There were not so many possibilities. They might be exhausted in a few weeks' investigation. Was there not, however, a shorter road to results?

"If I were in this lad's place," the detective again queried introspectively, "what would make me write home?"

"Obviously nothing would," came the answer, "so long as I could communicate through the safer medium of a trusted messenger."

"But if the messenger were an impossibility, would I write?"

This query the detective had some difficulty in answering. He brought himself to experience the lonesomeness and homesickness of the fugitive, the lad whose whole life interest was wrapped up in the little circle in which he had moved. At the same time he appreciated the fugitive's proven fear of the mails and his avoidance of them so far.

But for the sake of laying down a basis for action Detective Billy Gard granted that he would write if he could not communicate otherwise. If this were admitted what was to be done? Obviously the former methods of communication should be cut off.
