The lower part of his cheek--that side on which I sat--was sunk in, as if he had no teeth there.
The effect was to give his whole face a twisted appearance.

The greater part of his head, of course, was concealed by the flowing white kaffiyi, but his skin was considerably darker than that of the Palestine Arab.

He had no eyebrows at all, having shaved them off--for a vow I supposed.

Instead of making him look comical, as you might expect, it gave him a very sinister appearance, which was increased by his generally surly attitude.
Once again, as when I had entered the room, he turned his head to give me one swift, minutely searching glance, and then turned his eyes away as if he had no further interest.

They were quite extraordinary eyes, brimful of alert intelligence; and whereas from his general appearance I should have set him down at somewhere between forty and fifty, his eyes suggested youth, or else that keen, unpeaceful spirit that never ages.
I tried him again in Arabic, but he answered without looking at me, in a dialect I had never heard before.
