Murder on The Dark Web: A Detective Murder Mystery Thriller (The Inspector Sheehan Mysteries Book 4) Kindle Edition

by Brian O'Hare (Author) Format: Kindle Edition
4.6 out of 5 stars (45)

"A magnificent story that kept this reader turning the pages." ★★★★★


“I am Nemein. I am not a murderer. I am an instrument of Nemesis — a punisher.”

The anonymous manifesto floods the Dark Web, each post laced with intellectual justifications for a string of gruesome murders.

DCI Jim Sheehan and his Serious Crimes Unit are pulled into Belfast’s shadowy cyber underworld, chasing a cold-blooded, narcissistic psychopath who treats killing as philosophy.

Every lead collapses into a dead end. Then Nemein’s blog begins to name names — threatening Sheehan’s team, and his wife.

With the killer always one step ahead, Sheehan’s famed intuition is pushed to its limit.

But as the investigation finally locks onto its target, he faces an impossible choice: save his colleagues, protect the woman he loves… or stop a calculating predator who believes himself untouchable.

Murder on the Dark Web has received the Top Medal Honours Award from the New Apple Awards for Excellence.

Official Review by Readers Favourite Reviewed By: Divine Zape
Review Rating: 5 Stars -

Brian O'Hare has a refreshing voice in the crime and mystery genres, a clear and enjoyable one. The author plunges readers into the mindset of a serial killer and forces them to navigate the darkness that inhabits the killer's soul. From the beginning, the reader is gripped by curiosity and wants to discover more about the villain, but they quickly discover that the darkness is addictive, nourished by a grim, pervasive form of humor that rubs off on the reader. The author explores the darkest instincts of humanity and creates characters that are sophisticated and real. The novel is ingeniously plotted and the online presence of the killer gives the feeling of one who is everywhere and yet nowhere. The Dark Web Murders is suspenseful, psychologically disturbing, and emotionally engaging. An expertly written crime novel that leaves you with nightmares.

As Judge Neeson holds a party with well-established millionaires, other judges, and famous revelers, his judge's judicial assistant is said to have been tasked with meeting someone claiming to carry incriminating files on him. The following day the assistant finds the judge's house vacant with only Neeson's dead body left on the floor. Head bashed in and body assaulted beyond belief, Detective Chief Inspector Sheehan is put to the task of solving the murder of Judge Neeson.

Over the following weeks, Sheehan discovers that they are dealing with a provenly deranged serial killer as more bodies are uncovered. And as fate would have it, each murder is documented and justified by the killer on a blog posted to the Dark Web called "Niemen," which launched the same day Judge Neeson was discovered. Each post proceeds with decoding the meaning of old philosophies surrounding vigilante work and justice of the people and the fate of the victim the author decided to unleash these philosophies on.

Author Brian O'Hare's gripping book Murder on the Dark Web is filled with impressive realism and has been well researched. Rarely seen these days in a lot of fictional crime, the attention to detail truly makes this enthralling book stand out against the crowd. Using a slow-burn approach, the author introduces small details about the setting and crime scenes to the reader. This attention to detail continues throughout, creating a complex plotline. In the style of a hard-boiled mystery, O'Hare gives extensive and often gruesome details to his murder scenes. This reminded me of Dan Brown's works, which would leave readers with no doubt about the suffering the victims endured.

One characteristic that makes this unique novel stand out is the character development. Each character is distinct and memorable. The side characters are lovable and realistic, giving readers someone to relate to as they progress through some of the darker moments. The crimes have a poetic justice feel to them with the killer's use of philosophical ideas that presents a calculated series of killings.

Murder on the Dark Web is a riveting crime thriller that will have readers on edge till the end. The mystery behind the murders is engrossing as clues will lead readers down false trails and keep them guessing until the reveal.

About Brian O'Hare, MA, Ph.D

Brian O'Hare's early writing was academic but when he decided to write fiction, his success surprised him. His books have won several awards and his first mystery novel, Angel of Death, led to the award-winning Inspector Sheehan Mysteries series. There are eight books in the series with a ninth on the way.

Before retirement he was Assistant Director of the Southern Regional College in Northern Ireland. Married, with three children, ten grandchildren and three great-grandchildren, he now writes full-time. For many years he and his wife enjoyed travelling, especially in France. He also enjoys reading, chess and plays golf twice a week.

Reviewers say that O'Hare writes with a keen eye for detail with his tales evolving at a surprisingly fast pace, that he leans towards the human side of his characters,that he imbues them with a real-world presence that is in turn witty and passionate. If you are interested in discovering whether or not there is any truth to these judgements, the novels are available on Amazon, sometimes at a reduced rate.

    5.0 out of 5 stars Magnetic read!

    What an intriguing and chilling story in Murder on the Dark Web by Brian O'Hare. I have read stories from this author before, and I am a definite fan of this author! Whatever this author writes, I want to read. The Inspector Sheehan mysteries are one of my favorite series. I've read them out of order, but each one is a standalone, and I want to make sure I read all of them. This story revolves around the dark web which is way beyond what we know as the internet, not just the dark side of the internet, but where people can be whoever they want to be, dark or not. Sometimes once in a while, there is that one username that is way beyond dark, and this time the psychopath has a dark web blog, almost taunting and bragging about what he is doing. So, that's all I'm giving you, read the book. It's a wild and unimaginable place, especially inside this killer's head and his side of the dark web. You don't have to know code or technical jargon to read this book, it's your cat-and-mouse game on the web and in IRL ...Real Life... for Sheehan and his unit and this serial killer. It's magnetic, so much you can't put it down. It is a very well-written plot, and I enjoyed it. It is always an honor to read this author's books. Both thrilling and intriguing, all the way to the end. A reader can get lost in the story. And it's a new twist on a modern-day mystery slash thriller! This is a magnificent story that kept this reader turning the pages. Murder on the Dark Web is a definite recommendation by Amy's Bookshelf Reviews. I read this book to give my unbiased and honest review. Amy's Bookshelf Reviews recommends that anyone who reads this book also write a review.
