She wondered whether the isolation of his life at Overton had anything to do with it, whether contact with other children of his own age would reduce him to the normal. She took the risk, and sent him at the age of twelve, to a preparatory school in Cheltenham. Before the first term was half over they sent for her and asked her to remove him. The head master confessed that the case was beyond him. On the surface the boy was one of the most charming in the whole school, but his heart was an abyss of the most appalling blackness. Mrs. Payne entreated him to tell her the worst. He hedged, said that it wasn't just one thing that was wrong, but everything--everything. She asked him if he had ever known a case that resembled Arthur's. No, he thanked Heaven that he hadn't. Could he advise her what to do? Lamely he suggested a tutor, and then, as an afterthought, a mental specialist. The word sent a chill into Mrs. Payne's heart. The idea that this bright, delightful child, the idol of her hopes, was the victim of some obscure form of moral insanity frightened her. But she was a woman of courage and determined to know the worst. She took him to a specialist in London. Arthur thoroughly enjoyed this desolating trip. The specialist talked vaguely, leaving her nothing but the faintest gleam of hope. There were more things in heaven and earth, he said, than were dreamed of in the philosophy of the most distinguished alienists. He talked indefinitely of internal secretions. It was possible, he said--and underlined the word--possible, just barely possible, that in a year or two--to put it bluntly, at the time of puberty--the boy's disposition might suddenly and unaccountably change. He implored her not to count on it, and assured her that, for the present, medical science could do no more. If, by any chance, his prophecy should be fulfilled, he begged Mrs. Payne to let him know. The case, if she would pardon the use of this objectionable word, was one of the greatest professional interest. She took Arthur back to Overton and waited desperately. Tutor succeeded tutor. Each of them found Arthur charming and impossible. For herself she saw no change in him that was not physical. By this time she had abandoned any idea of finding him a profession. At the same time, she was anxious to make him capable of managing the Overton estate, and though she dared not send him to one of the ordinary agricultural colleges for fear of a repetition, on a larger scale, of the Cheltenham disaster, she thought that it might be possible to find a capable land-agent who would give him some kind of training and put up with his idiosyncrasy for the sake of a substantial fee.
