This is what I said to myself: Here is my darling working day and night to get at the heart of a great mystery in which he is involved. He endures dreadful hardships, suffers imprisonment and cruel indignities, and travels hundreds and hundreds of miles, in his endeavour to unravel the mystery which affects his peace and mine--his future and mine--his honour and mine! And here am I, with nothing to do, living close to the very spot where the fearful crime was committed, sitting down in wicked idleness, without making the slightest attempt to assist the man for whom I would cheerfully die, but for whom I would much more cheerfully live. Why should I not go and live in Great Porter Square, assuming such a disguise as would enable me to hear everything that was going on--all the tittle-tattle--all the thousand little things, and words, and circumstances which have never been brought to light--and which might lead to a clue which would help the man I would much more cheerfully live for than die for? There was no impropriety in what I determined to do, and in what I have done. I must tell you that there is in me a more determined, earnest spirit than you ever gave me credit for. Now that I am actively engaged in this adventure, I know that I am brave and strong and cunning, and a little bird whispers to me that I shall discover something--God alone knows what--which will be of importance to you. Do you think I shall be debarred by fear of ghosts? I am not frightened of ghosts. Now you know how it is I arrived at my resolution. Do not blame me for it, and do not write to me to give it up. I do not think I could, even if you commanded me. I did not make a move until night came. Fortunately, it was a dark night. I watched my opportunity, and when nobody was on the stairs, I glided down in my disguise, slipped open the street door, and vanished from the neighbourhood. I had never been in Great Porter Square, but it seemed to me as if I _must_ know where it was, and when I thought I was near the Square I went into a greengrocer's shop and inquired. It was quite close, the woman said, just round the corner to the left. The Square, my dear, as you know, is a very dismal-looking place. There are very few gas lamps in it, and the inclosure in the centre, which they call a garden, containing a few melancholy trees and shrubs, does not add to its attractiveness. When I came to 119, I crossed the road and looked up at the windows. They were quite dark, and there was a bill in one, "To Let." It had a very gloomy appearance, but the other houses were little better off in that respect. There was not one which did not seem to indicate that some person was lying dead in it, and that a funeral was going to take place to-morrow.
