Goodreads Synopsis:

LAPD Detective Margaret Nolan returns in The Devil You Know, the next book in the series where P. J. Tracy “seems to have found her literary sweet spot” (New York Times Book Review).

Los Angeles has many faces: the real LA where regular people live and work, the degenerate underbelly of any big city, and the rarified world of wealth, power, and celebrity. LAPD Detective Margaret Nolan’s latest case plunges her into this insular realm of privilege, and gives her a glimpse of the darkness behind the glitter.

The body of beloved actor Evan Hobbes is found in the rubble of a Malibu rockslide a day after a fake video ruins his career. It’s not clear to Nolan if it’s an accident, a suicide, or a murder, and things get murkier as the investigation expands to his luminary friends and colleagues. Meanwhile, Hobbes’ agent is dealing with damage control, his psychotic boss, and a woman he’s scorned. But when his powerful brother-in-law is murdered, he and Nolan both find themselves entangled in a scandalous deception of deadly proportion that shakes the very foundation of Hollywood’s untouchables.


First Line:

The ocean was singing in the hushed undulating tones of low tide on this still, damp night.

The Devil You Know by P.J. Tracy

While reading this book, I realized I need to read more mysteries that are only mysteries. I read romance, paranormal, and horror mysteries but never just plain secrets (if that makes sense). So, I was eager to read The Devil You Know. While I liked the book (and the story), I needed clarification during parts of the book. I don’t particularly appreciate being confused when I am reading. That did make for a less-than-ideal reading situation for me.

The Devil You Know had an exciting plotline. Detective Nolan has been assigned a disturbing case. A famous actor has been discovered dead in a rockslide. The death is suspicious because the day before, he had been the subject of a deepfake video that ended his career. Within a few days, the top executive where that actor worked is found murdered. The person that links the actor and the executive: the agent representing him and his family ties to the executive. It is up to Nolan to determine if the actor was murdered, committed suicide, or died in an accident. While doing that, she is assisting in the murder investigation of the executive. What Nolan finds out is so earth-shattering that it will shake her to the core. What does she find out? Who was willing to frame a well-liked actor in a deepfake video? Why? And how is the executive’s death connected to it?

The Devil You Know is the 3rd book in that Detective Margaret Nolan series. While readers can read this as a standalone, I recommend reading the books in order. Some parts of the book made me scratch my head because I didn’t know the backstories.

The characters in The Devil You Know were well-written, but I felt a certain disconnect with them. If I had read the first two books, I would have understood more about Nolan’s background. I also would have understood more about some of the secondary characters.

  • Detective Nolan—I liked her. She was smart, and she worked well with others. But there was also a sad element to her character. I feel it was because of her brother’s death (which is linked to another secondary character). She also emphasized with the victims’ families and, weirdly enough, the murderer. I loved seeing her process of finding out who the murderer was.

The Devil You Know fits perfectly in with the mystery genre. I loved the red herrings that she put out!! Talk about distracting, and I did feel bad for those two women (as vile as they were). The author kept me guessing until the end.

The storyline with Detective Nolan, the actor’s death, the deepfake, and the investigation were wonderfully written. The author had me double guessing if it was an accident (because of testimony from his friend/hostess of the party). Even when it was determined a murder (and no, not a spoiler, the detectives figured it out fairly early), I loved watching the investigation turn to suspects. There was another murder (with the same MO) and the revelation of the murderer. I was shocked at who it was because I didn’t see it coming. I also did feel bad for that person because of the trauma that person endured. But still, no excuse. Oh, and let’s not forget the deepfake. That was the cherry on top of this whole investigation. Once they figured out who it was, it was all downhill.

The storyline with Detective Nolan, the executive’s death, and the investigation were as wonderfully written as the first investigation. The author kept this one more under wraps than the other investigation. But still, I liked seeing how the detectives investigated it in tandem with the actor’s murder. There was a twist to that plotline that wasn’t revealed until the very end of the book. One that made me go, “Holy crap.” Because whoever went to jail for his murder didn’t kill him. The real killer’s identity stunned me.

The storyline with the agent, murders, his relationship with the movie star, and then his murder did take me for a ride. For the longest time, I thought the same thing Detective Nolan did. He did it and covered it up. Of course, there were a few red herrings sprinkled in that storyline. The big twist in that one was how the detectives figured everything out. I won’t say what, but he was a pretty intelligent guy for doing what he did.

I went back and forth on putting a trigger warning on this book. I ultimately decided to do it because what was discussed was disturbing. My trigger warnings are mentions of child pornography, deepfake videos, drug use, and alcohol use. If any of these triggers you, I highly suggest not reading this book.

The end of The Devil You Know was okay. The author wrapped up the first two storylines, and I thought they were over. But then the author tacked on that final chapter that blew everything about the second murder out of the water. It was indeed a twist that took me by surprise.

I would recommend The Devil You Know to anyone over 21. There are language, violence, and sexual situations. Also, see my trigger warnings.

I want to thank St. Martin’s Press, Minotaur Books, NetGalley, and P.J. Tracy for allowing me to read and review The Devil You Know. All opinions stated in this review are mine.

December has flown by for me (I don’t know about you guys). I was stretched thin between my kids’ Christmas events, last-minute shopping, and the actual holiday. I hope January is less hectic and I can breathe again.
