I liked the vast cast of characters and the intricate mystery. 

I strongly disliked the execution - there was a lot of foreshadowing with very little payoff. The detective abruptly showed up 60% into the novel, everyone was running around being useless up til then.

The narrator was particularly unlikeable - she was prone to making erroneous judgements that gave her an air of prejudice and incompetence. There were a lot of race and gender stereotypes that haven't aged well that the narrator was frequently espousing.
