I've found it particularly difficult to write a review for this one. Whenever I tried to transfer my thoughts to paper ( ok ipad ) I found that ( in my excitement) I seemed to be giving away some small detail that would possibly spoil it for other readers. The shock and horror that I personally felt whilst reading this story, would have little value for others if they knew what they were about to read.

Unusually, the story begins with the death of the man known as The Fourth Monkey Killer, a kill

After finishing this book, I rated it three stars. I had just browsed the glowing reviews of fellow GR members and fell pray to the idea that I should like the book more than I did. But the more I thought about it, the less comfortable I felt with my rating. I just didn't think this book was very good.

It was kind of like reading Since We Fell all over again. Not only are both books bogged down by tedious (albeit, in this case, gory) backstory, but they also contain frankly ludicrous plot develop

I just loved this book. It was so terrifying and horrifying. Wow, this book is dark and creepy in the most wonderful of ways. It was just fantastic. I have been waiting for this book for quite awhile. It was also so demented, disturbing and gory. J.D. Barker is vivid in his descriptions. For example, at one point I was reading a scene that involved a rat and could picture everything clearly in my mind. The author really knows how to get into your head. I hate rats. They are so disgusting.

Okay, there were some things I didn't like but overall, I loved it! I was not expecting the awesomeness and totally psychoticness of the killers up bringing!

I didn't really give a rats ass about the police stuff. Half of their stuff was stupid anyway. But the killers DIARY had me glued!! Reading about his life as a young boy and his whackadoo family. It was diabolical!

Anyhoo, it was awesome and I'm glad I read it!

Happy Reading!

This has to be one of the most sick and twisted books I have ever read...I LOVED every moment!

I’m going to keep this short because I don’t want to give anything away. A cat and mouse game ensues between a detective and serial killer when the killer gifts the detective with his diary, which tells the story of his extremely disturbing childhood. The voice of the serial killer jumps off the page and lures the reader into his deranged world.

All I can say is...WOW!

Inside the depraved mind of a serial killer. The cold, chilling evil.

So what is it about serial killer books? Curious, human nature I suppose. This is my third one this month, and by far the most disturbing. Normally I avoid these but they seem to be “creeping” into my library. Each one getting darker and more sinister. And I’m so glad I picked this one up. Everything you’ve heard about this book is's just that good!

This is a horrific serial killer thriller that will have you reading non stop till the end with its gripping narrative.

For five years, Sam has been trying to get the Fourth Monkey serial killer, who sends three white boxes consecutively, containing the ear, the eyes and tongue of the victim alluding to the three monke ...more
The Fourth Monkey by J.D. Barker is a 2017 Houghton Mifflin Harcourt publication.
Spectacular!! J.D Barker has breathed new life into the tired- should have been retired- serial killer trope.

Chicago has been traumatized by the Four Monkey serial killer for the last five years. But, when a man dies in an accident, law enforcement officials are positive he’s the 4MK killer. An unusual way to begin the story, for sure.

But, the kicker is that his latest victim is still alive out there somewhere.

All I can say is WOW! and thank you so much to my dear friend, Kaceey for encouraging me to read this book! You only told me I don’t know how many times that I needed to read this book and now I know exactly why!!! 5 Thrilling Stars!

THE FOURTH MONKEY (A 4MK Thriller, #1) by J.D. BARKER is a dark, thrilling, chilling, creepy, and suspenseful mystery/thriller/police procedural novel that was a captivating, gripping, and fast-paced read that was extremely hard to put down. I absolutely loved this o
I absolutely loved this! Deliciously depraved & darkly deviant. A chilling serial killer, a novel so creepy & horrifying from the outset, from an exciting relatively unheard of author. Fabulously disturbing and the sickest thing I have ever read. If these statements don't pique your interest, nothing will!

For me this is going to be a book hangover kind of book. What do I read next that will hold my attention as much as this one did?

(I'm trying not to spoil anything in the book so my review is my mind.)

You should all know that little saying with the monkeys..see no evil, hear no evil, speak no evil?

The four monkey killer takes that to extremes. He has four little monkeys by adding in 'do no evil'...those monkeys are evil little henchmen. Just saying.

THE FOUTH MONKEY (4MK) by talented author J.D. Barker is a dark and twisting novel; a combination of Se7en meets The Silence of the Lambs. Psychological thrillers are my favourite genre so was very much looking forward to reading it. As I started to read it, I was transported to a time when I watched my favourite movie, Se7en. I was drawn and hooked to this book, and had work not got in the way, I would have finished it earlier.

In this captivating series debut, J. D. Barker pulls the reader into the depths of a serial killer’s mind and how a spark in youth can erupt into a wildfire of indifference. Chicago Homicide Detective Sam Porter has been working to capture the Four Monkey Killer for over five years, watching as the victim count mounts with minimal clues, saving the severed pieces sent in boxes. When called to the scene of an early morning pedestrian-vehicle accident, Porter is baffled as to why he would be invol ...more
WOW WOW JUST WOW! Seriously, I rarely, almost never giver thrillers a 5 star rating but WOW! This a book like no other, like one I haven't read in years! It has the same components as most: a serial killer, a team of cops, clues, and gore - if you cannot handle gore then stop now because this book has it in buckets! What makes this book different is the humanity of each of these components.

In two most intriguing methods, a diary and a twist, you truly get to know the killer in a way we haven't

I finished this book with a dropped jaw and wow, it was just excellent.

The Fourth Monkey was certainly a dark, twisted and disturbing read and I absolutely loved this book. I was honestly so impressed by how clever the plot was, and the brilliant writing style had me completely immersed in the story.

Barker really knows how to write fleshed out characters; some were really likeable whilst others were quite detestable. The killer’s diary really drew me into his mind and gave me an insight on the
What a ride this was!

I was hooked from the start and with each turn of the page became more and more obsessed. I could NOT put this down!

Top 5 things I loved:
1) The Diary chapters-amazingly creepy and disturbing, but captivating at the same time. I love when an author allows the reader to go inside the life and mind of a psychopath.
2) Detective Sam Porter's character. He's smart, vulnerable and funny. The sarcasm playing between him and Nash helped balance out some of the disturbing violence.

Well, this is a weird one! First off, it starts with the death of the suspected serial killer. The detectives find a diary on his body. And it’s the diary that really provides a wild story. It details an event in his boyhood that explains why he is the way he is. Can we say sick? I’m talking a seriously whack job family.

This grabbed my interest from the get go. It’s a very fast paced story. The story bounces back and forth between the police trying to find the identity of the killer and the loc

I tried to go into this book with low expectations. I saw it everywhere last year and it’s my preferred genre. I just love suspense and police thrillers.

Well, I was not disappointed. I loved this book, the characters and the overall mystery of who the 4MK killer was. I don't want to say more about the killer due to spoilers or even give readers a hint. I think the less you know about the plot and charac

The long and short of this is: A serial killer has been terrorizing Chicago for over five years. The serial killer has become known as the Fourth Monkey (See No evil, Speak No evil - you get the picture). Then one night, his body is found. Police on the scene believe that he was on his way to deliver a message about a victim - who may very well be still alive. Detective Sam Porter has been the detective on the case.

“There is a fourth monkey, but nobody really knows about him,” I explained. Father nodded. “The first three monkeys define the rules we should all live by, but it’s the fourth that carries the most importance.” “Shizaru,” I said. “His name is Shizaru.” “He stands for do no evil,” Father said. “And that, of course, is the rub.

I must admit that this book is slightly derivative. There's only certain ways to write a gruesome story. But even if many authors are doing it, it's still a difficult job. Like Barcelona winning the treble.

Sam Porter is deliberately a common down-to-earth name. He is no Holmes or Poirot, but he has an eye for detail and a knack for connecting ideas. He also thrives under pressure. Sam is a working class hero in spirit.

The violent acts here are celebrated, and who can argue with the readership th

I mean....bitch, please...

This was exactly what I needed this year. Are you effing kidding me? It's SO GOOD.

Favourite movies: Se7en and The Silence of the Lambs. This book? A perfect lovechild of those two things but without being too much like those comparisons. You know what I mean?

It's new. It's different. But familiar and satisfying.

It's bloody and twisted and gory and clever and fun.

There's a new serial killer in town and he is a doozie! Chicago is used to seeing dark things ..but no one has seen the likes of this killer.

It all starts with the death of a man .... who was carrying a box with an ear to be delivered to a businessman. He jumps in front of a bus and is instantly killed.

Is this the 4MK killer that Detective Porter has been hunting for the past few years?

This is one of those books I just could not put down for more than a couple of minutes without picking it up ag

For those that haven't read this book, half of the chapters are told via a diary written by the serial killer depicting a very brief time in his childhood. The other chapters involve detectives trying to catch the adult version of said serial killer.

Ok, now that we're all caught up....'s how this book SHOULD have been written:

The entire first book in this series should have been about the childhood of the killer leading up to his current murder spree.

I loved this. It is so beautifully twisted that I don’t even have a word for it. I banged through it, unable to look away, often freaking out slightly, J D Barker writes with such visceral reality that you just fall into it stuck between horrified and fascinated.

So it is a serial killer thriller, which is an actual thriller, whilst being clever and manipulative enough to keep you guessing and with some characters of great depth and perception. I loved Sam Porter and his back story drip fed to us
