The Devil You Know: A Mystery (The Detective Margaret Nolan Series, 3)

Darkness is nothing new to LAPD Detective Margaret Nolan, but in P.J. Tracy’s The Devil You Know, even she isn’t prepared for the scandalous deception of deadly proportions that shakes the very foundation of Hollywood and its untouchables…and leaves her entangled in its rotten core.

Los Angeles has many faces: the real LA where regular people live and work, the degenerate underbelly of any big city, and the rarefied 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 decay behind the glitter.

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’s agent is dealing with damage control, his psychotic boss, and a woman he’s scorned.

This is the third novel in the Detective Margaret Nolan series. The Devil You Know is a well written, fast paced, entertaining crime thriller. I loved that our protagonist is a likable, intelligent, strong, and capable Female Detective.

The body of actor Evan Hobbes is found in the debris, after a Malibu landslide. The day before the landslide Evan was threatened with a video that shows him in compromising acts. Evan knows that this is a deep fake, yet he knows this could ruin his career.

Was it an accident, suicide, or Murder. Detective Nolan must solve this, all the while the body count continues to rise.

There were a lot of moving parts and characters to keep up with, but I really enjoyed the twists and turns that I did not see coming. I think that this was the best book in the series. (#1 Deep Into The Dark #2 Desolation Canyon)

I would like to thank St. Martin’s Press, Minotaur Books, NetGalley, and author, P.J Tracy for providing me the opportunity to read an ARC of this book.
