I sat in the window with the volume in my hand, but my thoughts were far from the daring speculations of the writer. My mind ran upon our late visitor,—her smiles, the deep rich tones of her voice, the strange mystery which overhung her life. If she were seventeen at the time of her father’s disappearance she must be seven-and-twenty now,—a sweet age, when youth has lost its self-consciousness and become a little sobered by experience. So I sat and mused, until such dangerous thoughts came into my head that I hurried away to my desk and plunged furiously into the latest treatise upon pathology. What was I, an army surgeon with a weak leg and a weaker banking-account, that I should dare to think of such things? She was a unit, a factor,—nothing more. If my future were black, it was better surely to face it like a man than to attempt to brighten it by mere will-o’-the-wisps of the imagination. Chapter III In Quest of a Solution It was half-past five before Holmes returned. He was bright, eager, and in excellent spirits,—a mood which in his case alternated with fits of the blackest depression. “There is no great mystery in this matter,” he said, taking the cup of tea which I had poured out for him. “The facts appear to admit of only one explanation.” “What! you have solved it already?” “Well, that would be too much to say. I have discovered a suggestive fact, that is all. It is, however, _very_ suggestive. The details are still to be added. I have just found, on consulting the back files of the _Times_, that Major Sholto, of Upper Norwood, late of the 34th Bombay Infantry, died upon the 28th of April, 1882.” “I may be very obtuse, Holmes, but I fail to see what this suggests.” “No? You surprise me. Look at it in this way, then. Captain Morstan disappears. The only person in London whom he could have visited is Major Sholto. Major Sholto denies having heard that he was in London. Four years later Sholto dies. _Within a week of his death_ Captain Morstan’s daughter receives a valuable present, which is repeated from year to year, and now culminates in a letter which describes her as a wronged woman. What wrong can it refer to except this deprivation of her father? And why should the presents begin immediately after Sholto’s death, unless it is that Sholto’s heir knows something of the mystery and desires to make compensation? Have you any alternative theory which will meet the facts?” “But what a strange compensation! And how strangely made! Why, too, should he write a letter now, rather than six years ago? Again, the letter speaks of giving her justice. What justice can she have? It is too much to suppose that her father is still alive. There is no other injustice in her case that you know of.”
