This is a firecracker of an addition to the Manchester Noir series by Joseph Knox featuring DC Aidan Waits, the flawed and disgraced antihero shunted onto the nightshifts with his partner, DI Peter 'Sutty' Sutcliffe. Aidan has been assigned, along with Sutty, to protect the infamous terminally ill serial killer dubbed The Sleepwalker, Martin Wick, in hospital, and tasked with trying to ascertain the location of the body of one of his victims, Lizzie. Several attempts on Wick's life had been made ...more

To call this a rollercoaster of a ride is the understatement of the year. Seriously. I stayed up way past late on a work night to finish and even when I finally turned the last page, my mind was too wide awake to think about sleeping. Now, trying to write something about the experience two weeks later, I’m at a loss. I’m still stunned by the crazy energy of the last section of the book and the masterpiece that is this series as a whole. I just don't have the words to describe it. Joseph Knox wri ...more

Ten Stars again for Joseph Knox. W O W.
This is his third book, again a supernova noir Masterpiece!

Completely, utterly brilliant in every way. Astounding, astonishing, dark and wonderful and sad. The best book I’ve read since his The Smiling Man a year ago, and his extraordinary debut Sirens two years ago. This one is even better.

My copy is a pre-release proof, inscribed by Joe, and posted to me by the author's own hand ! This is the most excited I've ever been to read a book.

The Sleepwalker is the third crime thriller in the DC Aidan Waits series, however, I feel that this is both Knox's most accomplished and most compulsive story to date. Each instalment can be read independently without issue but starting at the beginning is recommended. Troubled soul Detective Waits is relegated to guarding duties where he will need to provide protection to dying serial killer, Martin Wicks. However, in the hope that Wicks is about to open up about the location of his last victim ...more

There really are very very few series out there at the moment that engage me and steal my time quite as much as Joseph Knox and the Aidan Waits novels- dark noir with a deep ironic humour running through the heart of them and a main protagonist who is the very definition of anti-hero.

The Sleepwalker is the third in the series following the brilliant Sirens and the confirmational The Smiling Man – both of which I adored with a fiery vengeance and highly recommended, both of which made my top ten

In brief - Damn that was a good read. Perfect? Maybe not - however I would happily bring out an extra star for enjoyment. Next one please!!

Waits and Sutty are off the nightshift for now. Their new task is quite simple. A man convicted of murder who Sutty arrested some years ago is terminally ill. He is hidden in a room in the local hospital and under armed guard. The idea is that Sutty (and Waits) will keep an eye on him.

The Sleepwalker, book three in the Aidan Watts series by Joseph Knox, is the very definition of a dark, gritty, nasty crime story. In a time when everyone is trying to out-grittty each other, Knox seems to do it almost effortlessly. Thus far, every book in the series is excellent, including this one.

The setting for this novel is Manchester, England, and, while you could sing about Here Comes the Sun in nearby Liverpool at one time, Knox’ Manchester is dark, gloomy, filled with abandoned buildin

Thank you NetGalley and Random House UK for this arc.

I requested this after seeing it come over my GR feed a couple of times. I did not realize that it was the 3rd in a series and read it as a stand alone. That will be corrected soon. WHAT a story! I like dark and twisted and a frenetic pace, but this one broke the speed of sound records for me. A very complex story line (with very complex characters, whose histories I need to catch up on). Definitely not a read for the squeamish.

Read this within the space of around 4 hours, so I’m definitely going to reread when I receive my signed copy from Waterstones. Truly incredible. The ending was not what I expected at all after reading ‘Sirens’ and ‘Smiling Man’, (both amazing pieces of work that I definitely recommend reading before ‘The Sleepwalker’) and I can only hope Joseph continues to write, as I am completely hooked! Before picking up ‘Sirens’ I had never considered that I’d be interested in this genre, but as soon as I ...more

This is an absolutely superb book! Joseph Knox showed himself to be a terrific writer in the first two Aidan Waits novels, Sirens and The Smiling Man, but in The Sleepwalker he really excels himself. The writing itself is powerful, the portrait of Manchester is graphic, and his depiction of the main characters is vivid. Aidan Waits has had a very chequered past and struggles to cope with his demons but he is a brilliantly intuitive cop, and his relationship here with Naomi Black is fascinating. ...more

I saw Joseph Knox’s The Sleepwalker in my Goodreads feed, and saw that it was available to read and review on NetGalley. So naturally, I had to get myself a copy (because of my obvious and possibly unhealthy love for the mystery/thriller genre). Three days later, I’m done with the book and can’t help but feel how similar the experience of reading it was to reading A Dark So Deadly by Stuart McBride, which introduced readers to the Misfit Mob.

Here’s why The Sleepwalker was even better than A Dark

To my shame this is the first Joseph Knox book I have read-something which will absolutely be remedied!-and it's no surprise to see that I loved it!
Grim, noirish and extremely engaging, it is easy to connect with Aidan Waits despite how enigmatic and stand offish he comes across. He leaves you wanting to know more.Check out his description of his partner-

I’m a huge fan of Joseph Knox’s gritty crime thrillers set in Manchester. There is a real sense of authenticity to the setting of these books, and I love how Manchester is brought to life, especially in the darker areas of the city where gang lords rule, which Joseph Knox paints in a vivid portrayal. His writing definitely makes you feel as though you are there.

Joseph Knox’s debut Sirens was one of the most hyped debut crime thrillers of 2017. Introducing his readers to his flawed and deeply corrupt detective Aidan Waits, it was gritty Manchester based tale of corruption and organised crime. Waits returned for a sequel in The Smiling Man, and now he returns once more in The Sleepwalker. In the previous Waits has been consigned to a nightshift patrol, his partner Peter “Sutty” Sutcliffe, an obnoxious and offensive older officer with a compulsion to rub ...more

The Sleepwalker – A trip into the darker side of Manchester

Joseph Knox has once again written an excellent thriller in which he brings back the darkest stain on Manchester’s Police force, Detective Aidan Waits. This is a book that is a must for every crime thriller reader, that is gritty with a smell of corruption never far away.

The Sleepwalker is the third book in the DC Aidan Waits series. Even though it is in a series, it can be read as a stand alone and you not be lost.

In the novel, Waits and his partner Sutty have been detailed to guard and attempt to locate the remains of a murder victim from a tight-lipped convicted murderer as he lays dying in a hospital ward.

The Sleepwalker is the fourth book in the Detective Aiden Waits Series. I haven’t read the other books in the series but I still couldn’t resist grabbing this one from NetGalley mainly because of the glowing reviews that I read when the book first came out. In addition, the blurb did grab my attention.

The story begins with Detectives Aiden and Sutty guarding a hospitalized inmate. The inmate is serving time for mass murder and a lot of people want him dead both in and out of prison. Things turn

When I saw THE SLEEPWALKER on NetGalley I requested it right away and I started reading it as soon as it landed on my kindle. I have been waiting more than a year for a new Aidan Waits novel and I found myself engrossed from the first page.

DS Aidan Waits and his sarcastic partner DI Peter Sutcliffe have a very dull and monotonous job to do: they have to babysit a serial killer who is slowly dying hoping that he confesses the place where he hid the body of one of his victims. Obviously, things do

I love it when I’m introduced to writers I’ve never read before, especially when I know they’re going to be new friends. That’s the case with Joseph Knox.

The Sleepwalker, which is published this month by Doubleday, is the third outing for Detective Aidan Waits and yet it’s my introduction to him. I really don’t know why. Why haven’t I read Knox before? He’s my kind of writer.

From the very first pages, when a young woman is lured to her death, the plot commands our attention. It’s not just the ea

Thanks you NetGalley for the advance copy of this book in exchange for an honest review.
Sleepwalker is the story of dirty cops who are the good guys, and dirty cops who are the bad guys, everyone has something to hide, and no one is telling the truth as they manipulate people and facts to suit their own interests. The story is full of tough guy cop jargon, that made me wonder- Do people really talk this way? For example:

An absolute page turner! I haven't read the first two in this series but I don't think it impacted my ability to enjoy this book - or maybe just a tiny, little bit. I was immediately engrossed in the story line and was easily able to become comfortable with the characters. I did figure out the mystery, but I don't think it's because is wasn't well done, I think it was because, like the characters in the book I followed the clues the author provided and detected it on my own.

Wow where to start with this review. I haven’t read the first two books in the series but this was a thrilling gritty novel with Detective Aiden Waits who seems to have lots going on in his life. He has been relegated to night shifts barely hanging on to his job by a thread guarding a dying serial killer who asks to speak to his partner sulky but when he arrives someone kills the police officer guarding the prisoner and blows up the room where the prisoner and Aidens partner is with a fire bomb. ...more

However, I didn’t quite realise how important it would be to read the previous books beforehand.

Wow, what a ride. I had not heard of this author before so hadn't read the previous books in this series, but I will remedy that very soon.

This is an undeniably dark, gritty, complex novel, and it hooked me from the first page. Aidan Waits is a perfect anti hero - flawed, broken, complicatwd, compromised but what a compelling character. I was genuinely sad when he book came to an end, I had really grown to care for him. That is the mark of a well written book, and superbly crafted characters
