Book Description:
In the riveting conclusion of the 4MK trilogy, NY Times Bestseller Barker takes the thriller to an entirely new level. Don’t miss a single word of the series James Patterson called “ingenious.”
Hear No Evil
For Detective Sam Porter, the words “Father, forgive me” conjure memories long forgotten; a past intentionally buried. For Anson Bishop, these three words connect a childhood to the present as he unleashes a truth concealed for decades.
See No Evil
Found written on cardboard near each body, these words link multiple victims to a single killer—discovered within minutes of each other in both Chicago and South Carolina—clearly connected yet separated by impossible miles.
Speak No Evil
Chicago Metro and the FBI find themselves caught in chaos—a hospital on lockdown, a rogue officer, and corruption at the highest levels. When Anson Bishop, the prime suspect in the notorious 4MK serial murders turns himself in, he reveals a story completely unexpected, one that not only upends the current investigation, but one that will change the lives of all involved.
Do No Evil
With unrelenting tension and pulse-pounding suspense, the past unravels at breakneck speed as the truth behind the Four Monkey Killer’s motive is finally revealed in this masterfully crafted finale.
Jessica’s Review:
The conclusion to the #4MK trilogy! I was excited to finally read this! And I had planned to once I found out that Barker has a prequel trilogy coming out, the first in that series is out on September 22nd! I listened to all three in the trilogy back-to-back and it was one long and crazy adventure! The Anson Bishop/ Sam Porter combination is up there with Hannibal Lecter and Clarice Starling! I have only ever seen those movies, and must put the Silence of the Lambs books on my TBR to read.
At times The Sixth Wicked Child was very long winded and did drag on. There was a lot going on as the whole series has been that way, the direction just really wasn’t working for me. It just seemed like some could have been cut. BUT the final twists redeemed the book for me and I went for 4 stars to 4.5! Although I had some issues the ending was very satisfying for me and this series is definitely worth a read if you enjoy novels about serial killers. Just remember this series does get graphic!
I also enjoyed how all three books in the trilogy were brought together for the conclusion. Another thing to keep in mind with this novel: Do not believe ANYONE! I really was not sure where Barker was heading in this conclusion.
I am so glad we had both Edoardo Ballerini and Graham Winton narrate for the trilogy. Having a different narrator would not have worked for me. Their voices truly are these characters. And with the series coming to film/television soon in the future I cannot wait to see these characters brought to life! I just wonder who will be cast as Bishop and Porter!
Many thanks to JD. Barker and his publisher Hampton Creek Press for sending me paperback copies of this trilogy! I am starting The First Scarlet Door now!
