Another middle of the road. I think I've read this one before, though I didn't remember much of it. But the "mystery" was somewhat easy to guess quickly.
The relationship between Bosch and Anna is a bit boring, I hope she doesn't stay too long still. Maddie is the more interesting character at this point.
Also, I'm getting a little bit tired of the "morally gray" bits from Bosch, it's becoming less nuance and more of a caricature.
