The Dark Half

An author whose books sell OK and have a literary vibe to them. They don’t sell nearly as well as grisly crime thrillers he writes under an alter ego. Once his pseudonym is exposed, the author and his wife decide to give the other author a ceremonial burial. And then the people who were involved in doing that start turning up dead as it appears the alter ago has taken on a life of his own.

Unfortunately the movie The Dark Half is not yet available on HBO Max.
