Flow My Tears, The Policeman Said is a 1974 science fiction novel by Philip K. Dick about a genetically enhanced pop singer and television star who loses his identity overnight. The story is set in a futuristic dystopia, where America has become a police state after a Second Civil War. The novel was awarded first prize in the John W. Campbell Awards for the best science fiction novel of the year in 1975. It was also nominated for a Nebula Award in 1974 and a Hugo Award in 1975.
The novel is set in a dystopian future United States which is entering a post-totalitarian era with prospects of future democratic reform. Set in a then-future 1988, it extrapolates events from the late sixties and early seventies. These culminated in a "Second Civil War", also called the "Insurrection", which led to the collapse of democratic institutions in the United States and elsewhere.
