Dostoevsky, someone with probable PTSD, was a huge gambling addict and wrote The Gambler to pay off gambling debts (if I remember correctly); looked at roulette, his game of choice.
Was a phenomenally good read despite it being dry by comparison to something more modern.
Dostoevsky wrote Crime and Punishment and is a phenomenal author though not to everyone's liking.

I have a PDF of it and couldn't find one upon googling but I don't mind sharing books. There's no copyright on something that old either.
