The 39 Steps   - John Buchan

I stalked over the border of coarse hill gravel and entered the open veranda door. Within was a pleasant room, glass on one side, and on the other a mass of books. More books showed in an inner room. On the floor, instead of tables, stood cases such as you see in a museum, filled with coins and queer stone implements.

There was a knee-hole desk in the middle, and seated at it, with some papers and open volumes before him, was the benevolent old gentleman. His face was round and shiny, like Mr Pickwick's, big glasses were stuck on the end of his nose, and the top of his head was as bright and bare as a glass bottle. He never moved when I entered, but raised his placid eyebrows and waited on me to speak. 

I mean, even casual anti-Semitism and idiotic plots aside, there are lots of things wrong with this story, but wtf are "placid eyebrows"?
