The Killing Code: A Scottish Detective Mystery (DCI Logan Crime Thrillers Book 3) Kindle Edition

by JD Kirk (Author) Format: Kindle Edition
4.5 out of 5 stars 27,395 ratings
How do you catch a killer who doesn't exist?

After twenty years on the force, Detective Chief Inspector Jack Logan thinks he has seen it all.

He is wrong.

When a nurse is murdered on her way home from nightshift, Jack and his team go on the hunt for her killer.

As more victims are uncovered, Jack finds himself tracking a murderer afflicted by a unique psychosis - one that leaves him free to maim and kill without a shred of guilt or remorse.

Facing a new type of killer in an unfamiliar city, DCI Jack Logan is about to be pushed to his limits by an enemy he cannot hope to understand.

The Killing Code is the third DCI Jack Logan crime thriller, and perfect for fans of Ian Rankin, Chris Brookmyre, and LJ Ross.

    As a string of rapes and murders happen around a hospital, Jack Logan and his team of DCs are looking for a mad man that will not stop. This killer is cunning, bold, fast, and very smart. Those that may have lived through the attacks say the same thing, the killer would keep telling them " its not real, their all FAKE". Those that didn't make it, had FAKE carved into their bodies.

    So is this a parallel universe, that everything is fake, A Code, if you will? A Killing Code, that DCI Jack Logan must solve! Great book, that as the chapters pass, you follow along with the Detective as he solves the crime.

    While I would consider this book as filler, it moves the whole DCI Logan saga forward incrementally and needed. Kirk is a fine writer and a fresh breath of air for crime thrillers. I hope the best is yet to come.

    Reviewed in the United States on April 2, 2022

    If nothing really exists does anything really matter?

    The mad ravings of an insane killer? No, they are words debated in philosophy classrooms around the world.

    In this case they allow a mentally disturbed genius to justify his actions to his own sick mind. Or maybe they are only spoken to confuse his victims and the police.

    This plot device has been used before but not as effectively as JD Kirk uses it in THE KILLING CODE. It is a great read with more than a tinge of horror.

    I like the characters and the mysteries. The clues are fair enough that I can guess the bad guys. But the author must not like Harris. He kills his parents, has him kidnapped by a psycho, and has his sister abducted. What will he do next to this poor kid?

    I am reading this for the second time. Even though I know the outcome, the story and characters are so great I wanted to see them all again. I highly recommend the series for an interesting mystery with just enough humour thrown in to keep it from being to dark.

    I also highly recommend his other series Space Team (Barry J Hutchison) if you want an original, highly entertaining, laugh until you cry set of books to read. The audio books are fabulous too.

    Just Brilliant! I have read all three books in the DCI Logan series - I enjoyed the first two and found this third book the "best so far"! Very readable with a cunning plot and lots of twists and turns. The characterisation is amazing - I feel that I know them all. The interplay and humorous asides between Logan and his team - DI Ben Forde, DC Tyler Neish and all the other DCs is both relevant and brings a strong sense of humanity to the difficult, often soul-destroying role of the police force. I am looking forward to Book 4 in the series......

    Loved reading this too. Another completely different mystery this time which was equally interesting. However in this one, they don't really explain the motive of the murderer for doing whatever he does. There's no confession. Apart from that, a fun read.
