Sent 2: Nothing could be smarter, not anything better calculated to disguise a man.

Sent 6: Grim's skin had been sun-tanned in the Arab campaign under Lawrence against the Turks.

Sent 8: The khaki uniform had just enough of Oriental touch about it to distinguish it from that of a British officer.
Sent 9: No man inexperienced in disguise would dream of choosing it; for the simple reason that it would not seem to him disguise enough.
Sent 10: Yet Grim now looked so exactly like somebody else that it was hard to believe he was the same man who had been in the room ten minutes before.
Sent 11: His mimicry of the Syrian military walk--blended of pride and desire not to seem proud--was perfect.
