I found this very dark which I do enjoy. Initially I didn't realise that this was part of a series but it was easy to catch up and get involved with the story so much so that I will be investigating more in this series.

I was given a free copy by netgalley and the publishers but the review is entirely my own.

Dark thriller that had you hooked from the off. The book was very well written. Great plot. Very exciting. Fast paced to get your heart racing. Loved this book

A brilliant read, gripping and full of twists. I'm really looking forward to reading more from the author.

I would have liked this book more if I knew it was book 3 in a series. I struggled because I haven’t read the first two books.

Didn't know this was the third in a series but it doee makes a bit more sense when you learn this.

I have to say itvwas a bit slow in parts, could have been a bit shorter and snappier.

I would like to read the others to find out how they got to this point, hard to read as a stand alone, but thought the principle of the book was good, some twists and turns for sure

Firstly, I did not realise until after receiving this ARC that this was part of a series that I haven't read before.

This is the 3rd book in the Joe Stark series and whilst I found it enjoyable it does spend alog of time referencing events that have happened in previous books so I would recommend reading those first, its definitely not a book you can fully appreciate as a stand alone.

A decent paced storyline with well written, interesting and likeable characters

This was a good read bit I think it would have been alot better if I had read the previous two books in this series.

Thanks to netgalley and Penguin Michael Joseph UK for the ARC.

The Killer Inside is part of a series and perhaps I would have enjoyed this more if I'd read the previous two books. I love crime novels but found this to be a stilted and dull read. I was unable to engage in the plot or characters. Don't let my review put you off, maybe start at the beginning of the series.
Many thanks to NetGalley and the publisher for the opportunity to read and review this digital ARC.

I really enjoyed this book. It was a great storyline with excellent characters. I would highly recommend this book as it was a great read.

Julian Sinclair hunted and killed girls for fun but his conviction has been overturned. Both DC Stark and DS Mullhaven are forced to protect him even though they are sure he is guilty. However, whilst Sinclair is in hospital another girl is murdered, forcing them to consider if they had the right killer all along.

Unfortunately I struggled with this book and was disappointed as I usually really enjoy crime thrillers. I found the plot difficult to follow and struggled to keep track of the characters within the police force, I wish I read the other books in the series first rather than read this as a standalone as I think this would have helped me connect to the characters. As a result this was a slower read for me and I didn't feel in a rush to pick the book up.

The last half of the book definitely picked up pace as the suspense increased and I became more intrigued. There were a few clever twists that made me doubt my initial theories. Frank does a good job at portraying trauma and PTSD which he has done very realistically and this gave another important dynamic to the plot.

I do recommend reading this series in order as I feel this would have helped me understand and connect to the characters more.

A huge thank you to Netgalley and Penguin Michael Joseph UK for a copy of this book in exchange for my honest and unedited feedback.

This thriller has plenty of twists and turns
Will have you hooked from the first page
A great follow up to the first two books in this series
Thanks NetGalley

Like others who have reviewed this book, I hadn’t realised it was the third in a series. On saying that, I did feel enough backstory was provided so I didn’t feel like I had missed out by not reading the first two.

A pacy and gripping serial killer thriller (they’re the best type of thrillers, aren’t they?!) this story flies along, delivering some juicy twists and suspense. It’s pretty dark at times, and some readers may find parts distressing, however I like my crime reads dark.

I really liked the character of Joe Stark, the decorated war veteran now turned police officer. Your typical damaged yet endearing main character alongside his boss Fran, an equally damaged character. Sinclair, the convicted serial killer, made a great villain! Upon his conviction being overturned, an attempt on his life is made outside the prison, as he’s being released. Nature kicks in and Stark saves him. As he lies in hospital recovering, another girl dies… surely it couldn’t be Sinclair after all…? Fran worked on Sinclair’s original case and is hell bent that it is him. Stark isn’t so sure…

I was gripped to the end. Even though I saw the twist coming, I find this equally satisfying than when I don’t, as I love being able to work it out. As mentioned, I haven't read the first two in the series. However, I notice others have felt there was too much information or references to previous books. I’m not sure if this would detract from me now reading the first two, but I’m certainly not going to “not” read them, as I really enjoyed Matthew Frank’s writing style and the characters he has created. More than happy to recommend this book. Thanks to NetGalley for the ARC!

A brilliantly written thriller that will give you chills thrills the characters are well written and portrayed and the story is breathtaking.

I struggled to connect to the story so I wasn't invested in it. The writing seemed a bit clunky which meant I wasn't pulled into the world. It's so important to be invested in a thriller so that it feels tense and you want to know what happened. I unfortunately didn't really care. Did not finish.

A gripping thriller filled with plenty of twist and turns to keep you guessing till the very end. I didn't realise this was the third book in a series but the backstory was covered enough that it didn't matter.

A great storyline but the writing didn`t seem to flow for me.
Too much description and reverting back to previous books which I found very irritating.
The police think they have found the right man for several murders, but while he is in hospital another murder occurs so are the police wrong!
If you loved his previous books then you will love this, but definitely not for me.

Thanks to Netgalley for the ARC in exchange for my honest review.

This is a great read.
I didn’t realise it was the third book in the series, but there’s enough of a backstory to fill you in throughout the book.
DS Fran Milhaven and DC Joe Stark work together on a murder case which is complicated by the fact that the prime suspect was in hospital at the time of the murder. Sinclair had been convicted for previous murders but he recently had his conviction removed and was released from prison. He is then attacked at the prison gate and hospitalised which is when a further murder occurs.
Fran and Joe have their hands full trying to find the killer and I didn’t see the twists coming.
This is a gripping crime thriller that I really enjoyed.
Thanks to Penguin Michael Joseph UK and NetGalley for the opportunity to read this book

The Killer Inside is an ok read and has a solid plot. Unfortunately as it is the third in the series of Joe Stark books it falls into the trap of spending too much time referencing events that happened in the previous books.

For those that have read the previous stories it will feel like being preached at and makes for a clunky read without particularly enhancing the story. For those that haven’t read the previous two books it gives just enough detail to distract from the current storyline and will make you feel like you are constantly missing something causing confusion

Loved it - proper rollercoaster of a ride that I didn't want to get off!

At first, I didn't realise this was the third in the series starring Joe Stark as I have never read anything by Matthew Frank before but first the title and then the blurb enticed me and had I not read some other reviews first, I wouldn't have known. So, I can safely say that this can be read as a standalone because although I have probably missed a lot of backstory and character development, for me it didn't detract from my enjoyment one little bit.

I absolutely love the character of Joe Stark - yes, he is a bit of a cliché being ex-military with a troubled history now working within the police but, for me, this made him an interesting and complex character. The supporting cast were equally well developed and I think Julian Sinclair was a great "baddie".

At first, you think the plot is going to be pretty simple and straightforward but as the book progresses, it becomes more complex; the police investigation plays this out really well with them struggling to put the pieces of the puzzle together with many of their leads ending in dead ends. The politics within the police also provide an interesting side story as does Joe's complicated life.

This is fast paced with plenty of twists and action. It is also a dark read with some scenes that some might find disturbing so if you are easily shocked, I would give this a miss but I would definitely recommend this to others who enjoy this genre and eagerly await the next instalment.

Thank you to Penguin Michael Joseph UK and NetGalley for my copy in return for an honest and unbiased review.

3.5 stars rounded up to 4

Joe Stark #3

DC Joseph Stark's training as a decorated veteran taught him to always stay calm under fire. So when Julien Sinclair, a serial killer whose conviction has been overturned, is almost killed in front of him, Stark's survival instincts kick into overdrive, saving them both. When new victims appear while Sinclair lies in hospital, Stark and his partner DS Fran Milhaven are forced to look other suspects as well as investigate who would attack him in broad daylight.

This is a fast paced read with plenty of twists. It's a well written murder mystery. The plotline is complex. DC Joseph Stark and DS Fran Milhaven thought they had got the right man but his conviction was thrown out of court. I did guess where this story was going but it never spoils a good book for me. I quite enjoyed this book.

I would like to thank #NetGalley #PenguinMichaelJosephUK and the author #MatthewFrank for my ARC of #TheKillerInside in exchange for an honest review.

This book was not for me. I felt as if I was drowning in the various names of characters with little or not information on who exactly they all were. I found it one of the most confusing books I have read in some time. Very disappointed as normally a Penguin publication can be relied on to be a cracker. This one failed me miserably.
