This never would have stood out to me if it weren’t for the Pulp Revolution but Raymond Chandler seems to like to drop little mentions of pulps in his books. There was the one in The High Window, then in The Little Sister a character is said to have a “love-pulp” in his room.
Later when discussing a theory that the police have, Marlowe’s interlocutor dismisses it saying:
“Your cop friend has been reading pulp magazines.”
“They all do,” I said. “That’s why they talk so tough.”
