I drew back, apprehensively; then:—

"Ah! Dr. Petrie!" he said in a softly musical voice which made me start again, "to God be all praise that I have found you!"

Some emotion, which at present I could not define, was stirring within me. Where had I seen this graceful Eastern youth before? Where had I heard that soft voice?

"Do you wish to see me professionally?" I asked—yet even as I put the question, I seemed to know it unnecessary.

"So you know me no more?" said the stranger—and his teeth gleamed in a slight smile.

Heavens! I knew now what had struck that vibrant chord within me! The voice, though infinitely deeper, yet had an unmistakable resemblance to the dulcet tones of Kâramanèh—of Kâramanèh, whose eyes haunted my dreams, whose beauty had done much to embitter my years.

The Oriental youth stepped forward, with outstretched hand.

"So you know me no more?" he repeated; "but I know you, and give praise to Allah that I have found you!"

I stepped back, pressed the electric switch, and turned, with leaping heart, to look into the face of my visitor. It was a face of the purest Greek beauty, a face that might have served as a model for Praxiteles; the skin had a golden pallor, which, with the crisp black hair and magnetic yet velvety eyes, suggested to my fancy that this was the young Antinoüs risen from the Nile, whose wraith now appeared to me out of the night. I stifled a cry of surprise, not unmingled with gladness.

It was Azîz—the brother of Kâramanèh!
