If someone read only the 2 last books in the series that person couldn't possibly figure how the same author could write 2 books so different in tone and quality of writing. In this last work Tana French gives a new meaning to psychological thriller. She looks at every situation from all possible angles, examines in depth the consequences of each line of thought and very soon the reader finds him/herself in what feels like those mirror labyrinths not knowing who's who and who did what. Allow me a quote just to give you a taste: "That feeling, it’s not some bullshit figure of speech. It lives inside you somewhere deeper and older and more real than anything else except sex, and when it comes rising it takes your whole body for its own. It’s a smell of blood raging at the back of your nose, it’s your arm muscle throbbing to let go the bowstring, it’s drums speeding in your ears and a victory roar building at the bottom of your gut. I let myself love that feeling, one last time. I let myself drink it down, cram every second of it deep into me, lay away my store of it to last me the rest of my life." Well done!
