My situation was, to say the least, a most extraordinary one. Valiantly I strove to rid myself of the obsession which constantly crept upon me whenever my attention was not actually distracted by the new existence that had so mysteriously been opened up to me. For a little while I would let my mind dwell upon the terrifying thought that I was entirely helpless in the hands of one who was, without doubt, unscrupulous. I had pledged my honour to keep secret that appalling midnight crime, and to act always as directed. Edna herself, the woman whose voice sounded so tender, whose hands were so small and soft to the touch, had forced me to this. To her alone was due this state of constant anxiety as to what might next be demanded of me. The thought would creep upon me, now pausing, now advancing, until at length it wrapped me round and round, and stifled out my breath, like a death-mask of cold clay. Then my heart would sink, my sight seemed to die, even sound would die until there seemed an awful void--the void of death for ever and for ever dumb, a dreadful, conquering silence. A thousand times I regretted that I had in that moment of my utter helplessness given my promise to conceal the mysterious crime. Yet, when I recollected with what extraordinary ingenuity I had been deceived by the man whom I had believed to be a police-constable, the deep cunning which had been displayed in obtaining from my lips a statement of all the facts I knew, and the subsequent actions of the cool-headed Edna, my mind became confused. I could see no solution of the extraordinary problem, save that I believed her to be deeply implicated in some plot which had culminated in the murder of the young man, and that she herself had some strong personal motive in concealing the terrible truth. With the return of my vision my sense of hearing had, curiously enough, become both weakened and distorted. Sounds I had heard when blind presented quite a different impression now that I could see. The blind hear where those with eyesight can detect nothing. The ears of the former train themselves to act as eyes also, yet the moment the vision is recovered the sharpened sense of hearing again assumes its normal capacity. Hence I found that I could not distinguish voices and sounds so quickly as before; indeed, the voices of those about me sounded some how different now I had recovered my sight. My friends, into whose circle they declared I had returned like one from the grave, welcomed me everywhere, and I confess that, notwithstanding the oppression constantly upon me, I enjoyed myself to the top of my bent. I still remained in my dingy, smoke-grimed rooms in Essex Street, really more for Parker's sake than for my own, and also, of course, in order to be near Dick when he returned, but nearly every evening I was out somewhere or other, going here and there about town.
