Perfect for you if...

You love police procedurals with damaged protagonists who've seen real trauma and bring that weight to their casework.
You want a female detective who doesn't apologise for trusting her instincts, even when her mentor thinks she's reckless.
You're drawn to mysteries with high stakes and a killer whose obsession with the detective makes the danger visceral and personal.

Maybe not for you if...

You prefer cosy mysteries or procedurals where the violence happens offstage and stays clinical.
You need your detectives to be emotionally stable and by-the-book, without much of their personal baggage leaking into the investigation.
You're looking for a standalone; this is book four in a series and the relationships between Sydney, Bandoni, and Clyde will hit harder if you've read the earlier ones.

About this book

Newly promoted homicide detective Sydney Parnell, an Iraqi war veteran and former railway cop, becomes the youngest detective in Denver's Major Crimes Unit. When her instincts lead her and her K9 partner Clyde to investigate the murder of a man found tortured and beaten in a refrigerated train car with cryptic messages carved into his body, she must work with Len Bandoni, her former nemesis turned reluctant mentor. The victim belongs to an elite club called the Superior Gentlemen, which appears respectable on the surface but harbors darker secrets. As Sydney, Clyde, and Bandoni pursue the investigation, they uncover a shocking series of crimes and a horrifying conspiracy. Their bond deepens through the case, which threatens their lives and endangers their city.
