Jack's wife Kate was killed on her doorstep twelve years ago and Jack has never got over this. The killer has never been found and Jack looks closely at all the people he passes in the hope that some day he will find him.
One day Jack is astonished to see the killer in his local supermarket and can think of nothing else but to get the man to confess to the murder.
Events soon get out of his control as more and more people get drawn into this dangerous situation.
I really enjoyed this book I found parts of the books exciting and other parts amusing.
This is the second book I have read from this author, and I will be looking out for more of his work.
Thank you to NetGalley and Canelo for my e-copy in exchange for an honest review.

After recognising the man who killed his wife on her doorstep twelve years ago, Jack decides to follow him round the supermarket that they are in. All Jack wants is a confession from the man that killed his wife. But things quickly spiral out of control.

This is the first book that I have rad by the author and it won't be my last. It was not quite what I was expecting the book to be, it was much better. There is an element of comedy to the story. I liked the main characters. I also liked the authors style in writing. There is quite a few characters but don't let that put you off. They all have their part to play. I throughly enjoyed this book.

I would like to thank NetGalley, Canelo and the author S.B. Caves for my ARC in exchange for an honest review.

The first book I have read by this author, A KILLER CAME KNOCKING was nothing like I expected. I'm still trying to decide whether I liked it or not. On the one hand it was intriguing while on the other it was crazy! Some reviewers have indicated an element of comedy to the story, but I'm struggling to find anything amusing about it.

When I read that Jack Bracket had witnessed the murder of his wife on their doorstep some 12 years prior, I thought this was going to an intriguing search for the truth. What it actually turned out to be is a quest for revenge on so many psychotic levels. I can't even begin to go there.

When his wife Kate was stabbed in the neck when she went to answer the door, believing it to be their food delivery order, Jack was distraught. He never got over the senseless murder of his wife by what he believed to be a young teenager with the most piercing green eyes he has ever seen and a lust for blood. So when he is shopping in his local supermarket one day and he sees those same green eyes, his world stops. He has found him at last.

What ensues is a cat and mouse chase of sorts as Jack endeavours to find out who this man is - his name, where he lives and, most of all, why he killed his wife. He enlists the help of Kate's twin sister Emily, dragging her into his woeful search for justice. They hatch a plan, convinced that nothing could go wrong, to kidnap the man and convince him to tell them the truth...whatever that may be.

But it doesn't all go according to plan. They were seen, and now they have people looking for them as well. And not the good kind.

Then there is Jack's current girlfriend, May. She is something else. The woman is crazy, psychotic and completely unhinged. Her tantrums were next level. I started to wish something would happen to her. So when Jack calls off their relationship, she hatches a plan of her own. One that Jack cannot refuse...if he knows what's good for him. The way she can go from a loving and affectionate woman to a screaming psychotic beast within seconds is mind-blowing. By the end of the book, I had decided they truly deserved each other.

Jack finds himself with a conundrum on his hands. What to do with May? And what to do with the man who killed his wife? Emily proves to be of no help. She seesaws between helping him and abandoning him.

As events spiral out of control, more people are drawn into this dangerous situation. And Jack finds once he has started the ball rolling, nothing can stop it.

There was a lot going on at one point or another that in the end I felt some elements did not have closure. I'm not sure if this is where the author intends to leave it or whether he means to pursue it in a future release, but for me, it felt unfinished for some characters. It was certainly not what I expected.

A KILLER CAME KNOCKING is a dark read with an element of violence throughout. In my view, it's not overtly graphic but others may be of another opinion.

A fun read I would say, in most parts.

Jack's wife was murdered at their doorstep and Jack got a glimpse of the killer's striking green eyes. When he saw the same eyes at a local store, he was convinced the man was the murderer. He hooked his wife's twin sister Emily to help him.

My first book by this author, the book certainly went through a lot of turns, not all of them were logical. Jack's present girlfriend May added to the bizzareness of it. The writing gave it a cat and mouse feel to it. Things turned haywire when they decided to kidnap the man based on the color of his eyes. They were seen by more bad men who decided to go after him.

May added to the plot when Jack broke off with her. Now there were many after him and he was no close to the killer. There was so much going on in the plot that I got confused. The story came to a finish with many unanswered questions.

Because of the hotchpotch of a plot where too many things happened, I kept laughing. The book was quite insane. I didn't know if that was the good or bad part of it. Overall, a different read.

This was a wild story full of whack jobs, certainly entertaining but not all that satisfying.

I would have bumped up the rating but the writing just wasn’t for me. The dialogue was odd, off putting. There are twists and surprises and subplots to keep you on your toes (though some are left hanging).

May was a truly bizarre character, talk about mood swings. Jack devolved into quite the psychopath (sociopath??) too. Perhaps they deserved each other. Emily was the only occasional voice of reason, though a very weak one at that.

The end leaves some questions unanswered and does open this up for a second story. I’m still a bit chilled by it.

Thanks to NetGalley, the author and Canelo for a copy in exchange for a review.

This crime thriller started out strong for me and captured my attention. I was curious to find out what was going to happen as Jack runs into his wife’s killer. There were some truly thrilling and suspenseful moments, especially as his late wife’s twin sister becomes involved and goes to the murderer’s house to get a look at him.

There were many seedy characters and some secondary plot lines that added to the story build up, but many of them didn’t seem to come to fruition or matter in the end. Perhaps that was the point of them, and other readers won’t mind. I would have personally preferred a bit of a quicker moving plot without some of the extra hanging plot lines.

This was ultimately a dark read. There were episodes of graphic physical violence and disturbing scenarios. I would recommend this for readers who are looking for a crime novel thriller and are not disturbed by violence.

I loved this book! After spotting the man who killed his wife, Jack decides to get his revenge with the help of his dead wife’s twin sister. A very dark read filled with lots of humour. You get to meet lots of characters, each showing the ugly side of life. Very impressive book. Thank you to NetGalley and the publisher for my advanced copy.

This book was a crazy fucking roller coaster. It was also incredibly funny. A joy to read. Light hearted, but checks all the right boxes

I liked the twist at the end, but it seemed difficult to get there. There was a lot of different story lines that were connected, but it just kind of felt like TOO many story lines. All in all, it was ok, but I don't think I would reach for it again

An average read. It started off great and interesting but devolved rapidly into this bizarre tale. I’m all for exaggeration in novels but the plot became, quite frankly, ridiculous. Firstly, I refuse to believe Emily would willing go along with Jack’s plan (if we could even call it a plan). The character gave the impression of being cleverer than it. If there had been a solid plan, fine, but who would go into the situation blindly like that?? All because Jack saw green eyes. Emily’s had years to come to terms with Kate’s death and I’m just not buying that she would act emotional and irrationally the way she did.

Secondly, Jack isn’t smart enough to have pulled off an abduction/murder. He made numerous stupid mistakes. It was implied this may not have been his first and there’s no way he’d be able to commit a crime so serious and get a way with it. Too blasé about it all.

The plot was just far too unrealistic for me. That said, it was a fun read that kept me going through a shift at work. It was never dull, I’ll give it that. I quite liked the writing style as well. Probably wouldn’t recommend but certainly far from terrible.

This is an unusual story to say the least. There are no heroes in this story. In my opinion, there are not even any good guys in this story. The characters are made up of bad people and foolish people who all behave in boorish and ignorant ways. The main focus is on Jack, whose wife was murdered 12 years ago by a young man with distinctive green eyes. The police never solved the crime. Jack and his sister-in-law have been haunted by this brutal, unsolved murder for these past 12 years. Then one day by chance, Jack sees a man with distinctive green eyes and the need to solve the crime and obtain justice and or revenge races forward from there. Another problem for me is that the story ends inconclusively. That is, the reader is free to draw his or her own conclusion as to what happens after the final chapter is finished. I prefer stories that end with a definite conclusion.

What a massively disappointing ending. I saw a lot of people mentioning that this got a little boring mid-way through for them, but I was riveted and devoured this story in less than 2 days. I couldn't wait to see what happened, how everything would come to a head, maybe a big twisty moment at the end... but nothing happens. Not only that, but at least a half a dozen plot points are left unexplained, open- ended, or inferred.

This story had SO much potential. I was thinking that the fact that they were twins would tie in somewhere (case of mistaken identity, maybe?) but nope. The ending was a big slice of nothing pie. The two stars are for the build up- it kept me entertained, but man did my vibe come crashing down when I realized nothing would be answered.

This was a great read and maintained my interest throughout which few books have done recently.

The storyline was good and there were some tense moments. I could see where the storyline was going but I didn’t mind too much.

My only complaint was the choice of names for characters like Roger and Bernard ….. I don’t know anybody under 70 who go by these names. Craig is another name which you don’t hear in anybody under 50. I am wondering how old S B Caves is? I am guessing he is an older person.

Edited to add I have just checked and the author is a youngish person so I was wrong but he does write in rather an old style. Still a great read though.

Took me a long time to read this book. Honestly the story line was good but some of the chapters just weren’t necessary. I could have gotten away with just reading the epilogue and still understand what the entire book was about. The way the epilogue ended, I could see a second book (if there isn’t one already). I wouldn’t necessarily recommend the book.

Started off well and I couldn’t put it down but gradually just got abit same old same old.

A lot of physical violence scenarios and the ending doesn’t really provide any closure with any of the characters storylines.

Still not sure how I feel about it.

This was a thriller that just kept going, no real twists but plenty of turns. More action packed than suspense but still a solid story of loss, the way not knowing why eats at you and what limits you will might reach to get the answer.

The plot was nothing we haven't read in this genre of book. But the author did a good job of drawing me in and creating a very visual story. It reminded me of the TV show Dexter- not the plot, but the vibe. Darkly humorous and pulpy. And a very fast read. Nothing wasted, pure story.

I tried to like this book, unfortunately it was just to all over the place. It was almost a DNF.

It had some good moments, but overall a let down.
