Excerpt from the Thief by Jun'ichirō Tanizaki.

“A thief belongs

to a different species. . .” A thief! What a detestable name to be called! I suppose what makes a thief different from other men is not so much his criminal act itself as his effort to hide it at all costs, the strain of trying to put it out of his mind, the dark fears that he can never confess. And now I was becoming enshrouded by that darkness. I was trying not to believe that I was under suspicion; I was worrying about fears that I could not admit to my closest friend.

It also struck me that if even the most virtuous person has criminal tendencies, maybe I wasn't the only one who imagined the possibility of being a thief.
