I pulled this off the shelf in the house my family & I were renting for vacation. The synopsis sounded interesting, so I gave it a shot. The crime story - an arsonist lighting people on fire in their fancy Manhattan apartments - was fascinating and well-written. The twists and turns were great. I think the resolution was cut a bit short. I read the book over the course of a couple of days while on vacation, and couldn't put it down (and not just because I needed to return it to the shelf before vacation was over).The thing that makes this a three-star review instead of a four-star review is that I HATED the interactions of the two detectives on the case. At the beginning of the book, it's clear that female cop Rica has a crush on her soon-to-be-divorced male partner Stack. That dynamic could have been fine, could have been well-written and interesting. Unfortunately, it turned Rica into an unprofessional and at times desperate person. It was completely unnecessary to the story - the cops being in sync in their thoughts and processes didn't have to be because of a love affair, that does just happen with cops who aren't sleeping together. Instead of being a story of a powerful woman cop who rivals the skills of her well-respected male partner, it turned every scene with them into a game of just waiting for the cringe-worthy moment where Rica was no longer a skilled female cop, but a single woman desperate enough to sleep with her partner that she'll say inappropriate things at crime scenes, in the office, etc. It was incredibly frustrating and had a huge negative impact on my final thoughts on the book.
