talc triangle.

Evidently animal magnetism can leak through talc, for suddenly the
chauffeur glanced sharply round at me, as if I had called him. "Did you
speak?" he asked.

"Dear me, no, I shouldn't have dared," I hurried to assure him. Again he
transferred his attention from the road to me, though only a fraction,
and for only the fraction of a second. I felt that he saw me as an eagle
on the wing might see a fly on a boulder toward which he was steering
between intervening clouds.

"Why shouldn't you dare?" he wanted to know.

"One doesn't usually speak to lion-tamers while they're engaged in
taming," I murmured, quite surprised at my audacity and the sound of my
own voice.

The chauffeur laughed. "Oh!" he said.

"Or to captains of ocean liners on the bridge in thick fogs," I went on
with my illustrations.

"What do you know about lion-tamers and captains on ocean liners?" he
inquired.

"Nothing. But I imagine. I'm always doing a lot of imagining."

"Do you think you will while you're with Lady Turnour?"
