Brennan could not afford to tell anybody of his suspicion of James Holden's source of income, for the idea of a child's making a living by writing would be indefensible without full explanation. However, Paul Brennan resorted to reading of magazines edited for boys. Month after month he bought them and read them, comparing the styles of the many writers against the style of the manuscript copy left behind by James. Brennan naturally assumed that James would use a pen name. Writers often used pen names to conceal their own identity for any one of several reasons. A writer might use three or more pen names, each one identified with a known style of writing, or a certain subject or established character. But Paul Brennan did not know all there was to know about the pen-name business, such as an editor assigning a pen name to prevent the too-often appearance of some prolific writer, or conversely to make one writer's name seem exclusive with his magazine; nor could Brennan know that a writer's literary standing can be kept high by assigning a pen name to any second-rate material he may be so unfortunate as to turn out. Paul Brennan read many stories written by James Holden under several names, including the name of Charles Maxwell, but Brennan's identification according to literary style was no better than if he had tossed a coin. And so, blocked by his own guilt and avarice from making use of the legal avenues of approach, Paul Brennan fumed and fretted away four long years while James Holden grew from six to ten years old, hiding under the guise of the Hermit of Martin's Hill and behind the pleasant adult façade of Mrs. Janet Bagley. CHAPTER TWELVE If Paul Brennan found himself blocked in his efforts to find James Holden and the re-created Holden Educator, James himself was annoyed by one evident fact: Everything he did resulted in spreading the news of the machine itself. Had he been eighteen or so, he might have made out to his own taste. In the days of late teen-age, a youth can hold a job and rent a room, buy his own clothing and conduct himself to the limit of his ability. At ten he is suspect, because no one will permit him to paddle his own canoe. At a later age James could have rented a small apartment and built his machine alone. But starting as young as he did, he was forced to hide behind the cover of some adult, and he had picked Mrs. Bagley because he could control her both through her desire for security and the promise of a fine education for the daughter Martha Bagley.
