I’ve read a book where in one of the chapters the protagonist is stalking/watching a woman sitting at a restaurant and chainsmoking.
She looks old and ugly but has a lot of makeup and the protagonist is attracted to her even though he thinks she’s ugly.
After the woman left he sits at her table and steals the cigarrette butts which have lipstick on them. He smells and licks them i think.
I thought it may be from Zeno’s Conscience which is one of my favorites but im not sure and chatgpt says its not. It might be Russian, specifically Dostoevsky #entertainment source
