“It was three years ago, Mr. Weld, that he first darkened this doorstep,” she cried. “Three bitter years they have been to me. The school had fifty boys then. Now it has twenty-two. That’s what he has done for us in three years. In another three there won’t be one. And the Doctor, that angel of patience, you see how he treats him, though he is not fit to lace his boots for him. If it wasn’t for the Doctor, you may be sure that I wouldn’t stay an hour under the same roof with such a man, and so I told him to his own face, Mr. Weld. If the Doctor would only pack him about his business—but I know that I am saying more than I should!” She stopped herself with an effort, and spoke no more upon the subject. She had remembered that I was almost a stranger in the school, and she feared that she had been indiscreet. There were one or two very singular points about my colleague. The chief one was that he rarely took any exercise. There was a playing-field within the college grounds, and that was his farthest point. If the boys went out, it was I or Dr. McCarthy who accompanied them. St. James gave as a reason for this that he had injured his knee some years before, and that walking was painful to him. For my own part I put it down to pure laziness upon his part, for he was of an obese, heavy temperament. Twice, however, I saw him from my window stealing out of the grounds late at night, and the second time I watched him return in the grey of the morning and slink in through an open window. These furtive excursions were never alluded to, but they exposed the hollowness of his story about his knee, and they increased the dislike and distrust which I had of the man. His nature seemed to be vicious to the core. Another point, small but suggestive, was that he hardly ever during the months that I was at Willow Lea House received any letters, and on those few occasions they were obviously tradesmen’s bills. I am an early riser, and used every morning to pick my own correspondence out of the bundle upon the hall table. I could judge therefore how few were ever there for Mr. Theophilus St. James. There seemed to me to be something peculiarly ominous in this. What sort of a man could he be who during thirty years of life had never made a single friend, high or low, who cared to continue to keep in touch with him? And yet the sinister fact remained that the head master not only tolerated, but was even intimate with him. More than once on entering a room I have found them talking confidentially together, and they would walk arm in arm in deep conversation up and down the garden paths. So curious did I become to know what the tie was which bound them, that I found it gradually push out my other interests and become the main purpose of my life. In school and out of school, at meals and at play, I was perpetually engaged in watching Dr. Phelps McCarthy and Mr. Theophilus St. James, and in endeavouring to solve the mystery which surrounded them.
