I'm unable to finish this at this time. I think I gave it a good enough shot, made it to page 179.

The narrative is very in your face and there is little room for nuance, or descriptive details. The story seems to be driven by dialogue, because outside dialogue not much of interest is mentioned.

The dialogue isn’t very interesting either. Why do people even talk to Marla? Just because she’s asking questions? She doesn’t seem to strike up rapport with any of the people she speaks with, yet they continue talking to her.

Flipped ahead to find out who the murderer was.

Spoiler

By page 179 Marla hadn't even spoken to this person yet. There are a couple of mentions only.

That may be realistic in this situation, but in a murder mystery, all characters of interest should have met with the sleuth in the first third of the story.
