“The light exploded on my eyes and out of the darkness there emerged a frowning face with pursed lips that I knew but could not place. I moved towards it with hate in my heart. It was my adversary Mustafa Sa’eed. The face grew a neck, the neck two shoulders and a chest, then a trunk and two legs, and I found myself standing face to face with myself. This is not Mustafa Sa’eed— it’s a picture of me frowning at my face from a mirror” p.112.
