I asked myself that question as I finished Blind Man With a Pistol. This detective story had no resolution. You don't find out who the killer was. Instead, more killings take place in the last chapter.
The unresolved nature of the story is difficult for me to like. It reminded me of the game where one person starts a story, then another person picks it up from there, and so on. Fun, but not how I like my novels. This book is set in Harlem and it is one of those books where the author's goal is not necessarily to tell a story but get a message across. The message about the struggle the residents of the book face came through very clearly. I just would rather read a story, thanks.
