“None of you knew what it meant?”

“No.” The doctor made the admission as if half-ashamed of it. No mere Englishman—as Rukh perfectly knew—cares to be found lacking in omniscience itself, let alone average intelligence (one reason perhaps of the old dislike that the English once bore the quicker French).
