What is the main conflict in Farewell, My Lovely by Raymond Chandler?

Early in the narrative, Moose Malloy kills Mr. Sam Montgomery, current owner of Florian's night club. Philip Marlowe happens to be in the next room. Moose, who has been looking for his old girlfriend Velma, escapes and Marlowe agrees to help the police bring him to justice.

A secondary conflict can be found in Marlowe's determination to expose those behind the fake sanitarium and hot-boy safe house.
