Now, if it were true that the man who had been struck dead at my side was actually Mabel's friend, then I was within measurable distance of elucidating the mystery of that fateful night and ascertaining the identity of the mysterious Edna, and also of that ruler of my destiny, who corresponded with me under the pseudonym of "Avel." This thought caused me to revert to that hour when I had sat upon the seat in the Park, keeping a tryst with some person unknown. Seated in the corner of the railway-carriage I calmly reflected. More than a coincidence it seemed that at the moment my patience became exhausted, and I rose to leave the spot my mysterious correspondent had appointed for the meeting, I should have come face to face with the woman whose grace and beauty held me beneath their spell. For some purpose--what I knew not--I had been sent to that particular seat to wait. I had remained there in vain, smoking a dozen cigarettes, reading through my paper even to the advertisements, or impatiently watching every person who approached, yet the moment I rose I encountered the very person for whom I had for days past been in active search. Had Mabel's presence there any connexion with the mysterious order which I had obeyed? Upon this point I was filled with indecision. First, what possible connecting link could there be between her natural movements and the letter from that unknown hand? As far as I could discern there was absolutely none, I tried to form theories, but failed. I knew that Mabel attended at the Royal Academy of Music, and what was more natural than that she should cross the Park on her way home? Her way did not lie along the path where I had kept such a watchful vigil, and had I not risen and passed towards Grosvenor Gate at that moment we should not have met. There, indeed, seemed no possible combination between the request I had received from my unknown correspondent and her presence there. In my wild imaginings I wondered whether she were actually the woman whom in my blindness I had known as Edna, but next instant flouted the idea. The voice, the touch, the hand, all were different. Again, her personal appearance was not at all that of the woman described by West, the cabman who had driven me home after my strange adventures. No; she could not be Edna.
