1991 novel by Bret Easton Ellis
American Psycho is a horror novel by American writer Bret Easton Ellis, published in 1991. The story is told in the first-person by Patrick Bateman, a wealthy, narcissistic, vain Manhattan investment banker who apparently lives a double life as a serial killer. Alison Kelly of The Observer notes that while "some countries [deem it] so potentially disturbing that it can only be sold shrink-wrapped"... Wikipedia
