Thus far she chatted about herself quite freely; but when I tried, even in the vaguest manner, to lead her into discussing the causes of her strangely secluded life, she looked so distressed, and became so suddenly silent, that I naturally refrained from saying another word on that topic. One conclusion, however, I felt tolerably sure that I had drawn correctly from what she said: her father’s conduct toward her, though not absolutely blamable or grossly neglectful on any point, had still never been of a nature to make her ardently fond of him. He performed the ordinary parental duties rigidly and respectably enough; but he had apparently not cared to win all the filial love which his daughter would have bestowed on a more affectionate man. When, after reflecting on what Alicia had told me, I began to call to mind what I had been able to observe for myself, I found ample materials to excite my curiosity in relation to the doctor, if not my distrust. I have already described how I heard the clang of the heavy door, on the occasion of my first visit to the red-brick house. The next day, when the doctor again took leave of me in the hall, I hit on a plan for seeing the door as well as hearing it. I dawdled on my way out, till I heard the clang again; then pretended to remember some important message which I had forgotten to give to the doctor, and with a look of innocent hurry ran upstairs to overtake him. The disguised workman ran after me with a shout of “Stop!” I was conveniently deaf to him--reached the first floor landing--and arrived at a door which shut off the whole staircase higher up; an iron door, as solid as if it belonged to a banker’s strong-room, and guarded millions of money. I returned to the hall, inattentive to the servant’s not over-civil remonstrances, and, saying that I would wait till I saw the doctor again, left the house.
