As an addendum to my previous entry on Raymond Chandler's The High Window I offer the next passage in which Marlowe scans the photograph of the woman with the "cool dark eyes:"
I hung up and lit my pipe again and sat there looking at the wall. My face was stiff with thought, or with something that made my face stiff. I took Linda Murdock's photo out of my pocket, stared at it for a while, decided that the face was pretty commonplace after all, locked the photo away in my desk.
There's something about the way Chandler uses the word "something."
