Philip K. Dick
Flow My Tears, The Policeman Said (1974) is about Jason Taverner, a television star living in a dystopic near-future police state. After being attacked by an angry ex-girlfriend, Taverner awakens in a dingy hotel room. He still has his money in his wallet, but his identification cards are missing. This is no minor inconvenience, as security checkpoints manned by pols and Nats - the police and National Guard - are set up throughout the city to stop and arrest anyone without valid ID.
