I hesitated whether to return home by 'bus or Underground Railway, but, deciding on the latter, continued along the High Street to the station, and journeyed to the Temple by that sulphurous region of dirt and darkness known as the "Inner Circle." The reader may readily imagine how filled with conflicting thoughts was my mind on that homeward journey. Although I adored Mabel Anson with a love beyond all bounds, and would on that evening have declared my passion for her had I dared, yet I could not disguise from myself that sight of the pencil-case I had taken from the dead unknown had wrought an instant and extraordinary change in her. She had identified it. Of that fact there was no doubt. Her lame explanation that it bore a resemblance to the one she had given to her friend was too palpably an afterthought. I was vexed that she should have thus attempted a deception. It was certainly true that one gold pencil-case is very like another, and that a Birmingham maker may turn out a thousand of similar pattern, yet the intricate cypher engraved on the one in question was sufficient by which to identify it. It was these very initials which had caused her to deny that it was really the one she had purchased and presented; yet I felt convinced that what she had told me was untrue, and that those very initials had been placed upon it by her order. Again, had she not spoken of its owner in the past tense? This, in itself, was a very suspicious circumstance, and led me to the belief that she was aware of his death. If he were dead, then certainly he would no longer be her friend. Her sudden and abject amazement at seeing the pencil in my hand; her exclamation of surprise; her eagerness to examine it; all were facts which showed plainly that she knew that it remained no longer in his possession, and was yet dumbfounded to find it in my hand. Had she not also regarded me with evident suspicion? Perhaps, having identified her present, she suspected me of foul play? The thought held me petrified. For aught I knew she might be well aware of that man's tragic end, and the discovery of part of his property in my possession was to her evidence that I had committed murder. My position was certainly growing serious. I detected in the rather formal manner in which she took leave of me a disinclination to shake my hand. Perhaps she believed it to be the hand of the murderer. Indeed, my declaration that I had found that incriminating object was in itself sufficient to strengthen her suspicion if, as seemed quite probable, she was aware of her friend's tragic end. Yet I had really found it. It was no lie. I had found it in his pocket, and taken it as a clue by which afterwards to identify him.
