thank you @netgalley and @reddoorbooks for my advanced reader’s copy of this book!

Ali Davenport is a police officer who is forever haunted by one night that changed everything: the night she encountered the Knock-Knock Man. after working a horrifying case involving the death of a young boy alongside an older couple’s suicides, Ali and her colleague Ernie both swear that they spotted the Knock-Knock Man that night, a man that the young boy warned them about prior to his death.

while the case has continued to impact Ali’s mental state & professional credibility, she faces even more trauma after learning that Ernie was found dead at the building where he worked as nighttime security. though his death was ruled a suicide, Ali is more inclined to believe that this is all somehow related to the Knock-Knock Man. and she is not alone, as others suspect that the building has paranormal activity, and that the Knock-Knock Man may be the supernatural force himself.

Ali pledges to find answers on behalf of her friend Ernie after agreeing to take on his remaining overnight shifts. with the help of a young and curious ghost hunter named Will, she untangles a deep-rooted history about the Knock-Knock Man; though not without putting a huge target on all of their backs first.

i’m gonna be honest, this one didn’t do it for me at all. i thought it was incredibly slow and hard to follow along at times. it took me a long time to read because I just really wasn’t excited about finishing it. I didn’t find any of it scary or spooky, and the twists did nothing for me; in my opinion, they were far-fetched and didn’t resolve a lot of the plot. the title and cover had me stoked for a spooky thriller, but I was pretty disappointed despite my high hopes.

on a positive note, I have still seen some great reviews for it on Goodreads, so I encourage you to do more research on the book & check it out yourself if it sounds like something up your alley! published on May 19 and available to you now.

Who is The Knock-Knock Man? A ghost, a killer, or the figment of a frightened boy’s imagination?
It is a question that continues to haunt disgraced New Salstone police officer, Ali Davenport, fifteen months after the devastating case that changed the course of her life. Now, after the death of her former colleague, Ernie, Ali has returned home to face a past that won’t stay buried.
Found in the disused office building where he worked as night security, Ernie’s death has been ruled as a suicide. But not everyone is convinced. Wild stories are circulating about a supernatural presence in the building, an entity that might have attacked Ernie that fateful night. With the sale of the building about to go through, Ali is hired by its owner to work Ernie’s remaining night shifts and debunk the potentially damaging story. An easy enough job, if you don’t believe in ghosts. But then Ali meets Will, a teenage ghost hunter who claims to have evidence on film…
Forming an unlikely partnership, Ali and Will soon fall headlong into a mystery that takes them through New Salstone’s macabre history and into Ali’s own dark past. As the pieces of the puzzle come together, Ali is forced to face the question of The Knock-Knock Man one last time. But what Ali doesn’t know is The Knock-Knock Man has already been watching her for a very long time…

This is a very gripping read.
Wonderful well written plot and story line that had me engaged from the start.
Love the well fleshed out characters and found them believable.
Great suspense and found myself second guessing every thought I had continuously.
Can't wait to read what the author brings out next.
Recommend reading.

I was provided an ARC from NetGalley and the publisher. This is my own honest voluntary review.

This was a good thriller/paranormal/detective book. It is a bit to keep track of in the story because of how many little stories are playing out. It is about a mystery that kills people and the story follows our main character Ali as she deals with the demons of her past and faces her demons in the present. It is a good boogeyman type of story.

2.5 out of 5, rounding down to 2.

It took me so long to finish The Knock Knock Man, and I mean SO long. I don't think I can count on one hand how many times I almost gave up on it.

Don't get me wrong – it's not a bad book by any means. The first few pages were good... but after that, I simply couldn't get into it. The pacing was way too slow for my liking, and it felt like nothing exciting was happening until around the 60% mark. It wasn't until the 65% mark that I started really enjoying it, though. It's a shame, really, since I had high hopes for this book.

Also, I was constantly lost, even during long reading sessions. I don't have a problem with books that jump from scene to scene, as long as the transitions are good... which they aren't in this book.

Plot-wise, it was alright, I guess. I didn't find this scary, not in the slightest, but I actually like the twist. The writing was also pretty decent. It's really just the pacing that ruined it for me.

I found this book to be a definite page turner, though maybe I shouldn't have stayed up half the night just because I didn't want to put it down. I was jumping at noises outside!! It was different than the normal thrillers I read, but an author I will be adding to my reading lists.

That s is a difficult one to rate. On one hand it was spooky and the characters were pretty all right. on the other, this story crawled so freaking slowly and the writing was bigger down with a lot of unnecessary purple prose. This is certainly a mixed bag.

I requested this one because it might be an upcoming title I would like to review on my Youtube Channel. However, after reading the first several chapters I have determined that this book does not suit my tastes. So I decided to DNF this one.

This book was so creepy - but that was what I was expecting it to be.
At times, I got 'The Chalk Man' vibes from it - in a good way.
My only complaint it, I felt the book was a tad bit slow for my taste, except the pace, everything else was so enjoyable.

My Review - ⭐⭐⭐.5

Definitely a creepy read and not one to miss if you like a spooky read. I loved Ali & Will, thought they were really well written characters. I liked the mix of paranormal experiences mixed into a mystery/detective type story.

All in all a good read, not my fave of the year but a solid book

⭐️⭐️⭐️/5. Ali is a British police officer who recently got off a case that affected her so deeply she had to leave the force. Called back to action after her partners death. She starts to investigate further the crime that ended her career. This book was a mix of supernatural and crime thriller. It was a pretty good book and parts of it were amazing. It was a bit slow to start and Some parts fell flat and left me wanting more. I gave this book a 3 because it was overall pretty good but I was hoping for more. I received a copy of this book as an ARC and am leaving a voluntary review. Thank you to #netgalley and the author for letting me review this book!

I think there's a lot of potential and good ideas but the pace was too slow and it didn't keep my attention
Not my cup of tea
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine

Unfortunately, this was not for me. I found it too slow and not scary enough. But as you can see, I'm an outlier, so it might work for you.

A sharp, chilling mystery with tremendously engaging characters, written in taut prose. This book is original, suspenseful, and with complex characters that spring irresistibly to life on the page! Wonderful…

Ali left the police force in disgrace 15 months earlier following a bloodbath of a murder scene. When her former partner dies by supposed suicide, questions are raised about murder or involvement by the Knock-Knock man, described the night of the earlier incident by a teenage boy as a ghost or...something. It's unclear for most of the story if this is a supernatural thing or an actual person. This was good in that I was interested to keep reading and find out more, but I didn't end up liking the resolution of it all that much. 3 stars.

not for me but I think other people's might really enjoy this I just didn't click with the writing style but the actual story was interesting

I love a good paranormal thiller so I jumped at the chance to read the Knock-Knock Man. While the story was great, the dualling time lines, dream sequences and erratic characters made for a difficult story to follow.

This was a gripping read that was well written with a riveting storyline and well developed characters. It was dark and twisty and I couldn't put it down.

Thank you to the publisher and NetGalley for this ARC in exchange for an honest review!

The Knock-Knock Man by Russell Mardell is an absolutely terrifying horror/thriller novel that will have you scared out of your mind. The story revolves around Ali, a disgraced police officer who is being called back to deal with the stories of The Knock Knock Man, a figure that appears when you hear two knocks. Is he a real monster or the figment of a kid's imagination? Will Ali be able to figure it out before the Knock Knock Man comes for her next?

Here is a chilling excerpt from the Prologue:

"He thought of two more things before he died. He thought of his dear friend, Ali, and his guilt at not telling her the truth of that night when he had the chance. More than anything, he wished he had done that. Not to give her closure, at least not anymore, but to give her a warning. Then, before darkness drew down, and Ernie finally let go, another thought came to him as soft as a whisper. It was the same thought he'd had every day for the last fifteen months.
I don't believe in ghosts.
It seemed a little stupid now."

Overall, The Knock-Knock Man is an unputdownable horror/thriller that will appeal to fans of The Chalk Man or the Unsub series. One highlight of this book is how scary it was. It was. There were moments when I was scared to keep reading but also scared to look away. The "Knock Knock Man" in particular is such a scary concept. I did take off 1 star, because the ending was sort of unsatisfying. I felt like the terror that was so major in the beginning of the book ended up fizzling out by the end. If you're intrigued by the excerpt above, or if you're a fan of thrillers, I highly recommend that you check out this book, which is available now!

This book was riveting! I finished this book in about 4 hours. I could not put it down until I figured out who the ‘Knock Knock Man’ was! Ali seemed so sure she had figured out what she had seen all those years ago. Yet when she returned to,prove what happened to her ex-partner, she was pulled into the mystery all over again. This time around it seemed no one wanted the mystery solved. Any person getting close to the truth either died or disappeared. Would the same happen to Ali as she delves deeper into the information that Ernie found? You will have to read this chilling novel to find out.

This book is creepy!!! It's one of those stories that makes you question if things are real or not or if the monsters are supernatural or all too human. Read this really fast. I’d definitely say 3/5⭐️ Definitely a book I’ll be sharing about.

Thank you to #Netgalley for the ARC. I enjoyed it! I will be reading more of his books soon.
