Song: No Body No Crime by Taylor Swift and HAIM

“This isn’t a girls trip. It’s a murder mission.“

“It’s my signature. All serial killers need a signature.“

“He’s an ally.”

“So here it is. The moment I have truly been waiting for. The moment that I can wipe this repugnant piece of excrement off the face of the planet.”

“Wow, you know how I feel about men, but you have got yourself a king there, Kits.”

“I’m really into this body-disposal-but-make-it-luxe vibe we’ve got going on here.”

Thanks to Harper Collins and Katy Brent for my #gifted copy of this book. I love the Kitty Collins books they are darkly comedic which is exactly what I like. I finished it in just over 24 hours if that gives you any clue as to how much I loved it.

Kitty and her half sister Antoinette are on the hunt for Aiden Ward so they can avenge Kitty’s best friend Tor….Aiden beat the hell outta Tor in the last book. But there are new villains introduced and offed in this book.

I really loved how we got to see Charlie again. I was surprised with that part of the story because where we started and where we ended were completely opposite ends of the spectrum.

One question I have though is whatever happened to Lana Del Gay?! Maybe she’ll make an appearance in book 4 and help solve another mystery.

This is the 3rd book in the series and I’m hopeful there will be more. This is a series that just keeps getting better. It’s funny because the first book was decent but 2 & 3 were my favs. I actually read the first 2 in reverse order which really didn’t matter but I’d say you really should read book 2 before jumping into book 3 in order to really appreciate the characters and storylines.

This is one of my fav series of all time and I’m so glad I gave it a shot because there is no turning back now. I’m a Kitty Collins fan for life.

QOTD: What’s your favorite series?!

Book 3 in the series of kitty Collins does not disappoint ! What a ride a new location a new recruit and much more murdery fun ! I loved this and really hope there will be a book 4 ! Great story, great characters and some unexpected twists loved it !!!

[Vanessa Bill · Rating 5 out of 5]

This book is officially my favourite of the entire series and I had SO much fun reading it. The dynamic between Kitty and Antoinette was absolutely chef’s kiss. Antoinette brought such chaotic energy to the story and every interaction between the two of them was entertaining, funny, and completely addictive to read.

Katy Brent once again perfectly balanced dark humour, rom com vibes, shocking moments, and of course the very satisfying removal of awful men who absolutely had it coming. But what surprised me most in this one was the amount of empathy I ended up feeling for someone who so obviously deserved to die. Somehow this series always manages to make you laugh one second and question your own morals the next.

I also loved seeing Kitty continue to grow throughout the series while still giving us the sharp wit and murdery chaos that makes these books so entertaining. The twists, the humour, the characters — everything just worked for me in this one.

If you’ve been following Kitty’s journey from the start, you are going to LOVE this book. Easily my favourite in the series so far and one I absolutely flew through. 💋🔪

Book review….
Firstly I’d like to say thank you to Emma @hqstories and @but_katy_did_it For the proof copy of To all the men I’ve killed before, the final in the Kitty Collins trilogy. This is one of my favourite proofs I’ve ever been lucky enough to receive and I am genuinely grateful. Needless to say I started immediately not stopping until 2.30am on the day i received it, the book hang over was so worth it!

Official blurb - a man hurt your best friend – like, really hurt her – what would you do?
Key his car? Or hunt him down and chop him into little pieces? Tough decision, I know.
I’ve tracked this lowlife to LA and brought my little sister Antoinette along for the ride. I’m trying not to be irritated that she’s found a taste for murder and is leaving body parts all over our hotel. Because this girls’ trip needs a Hollywood ending.
And of all the men I’ve killed before, this one will be the sweetest…

My thoughts - I actually feel a mix of sadness with the excitement because it’s the last instalment of Kitty Collins! 🥺 I hope there’s some sort of Antoinette book in the future! I have to be careful what I say as I don’t want spoilers but I bloody LOVE kitty’s sister! The humour in this did not disappoint! The bit about the over dose was hilarious ( you’ll see!) my favourite quib in the book! 😂 what can I say my humour is twisted lol! Love all the characters, well most lol, this was my favourite of them all! I could not put it down and the ending 👌🏼👌🏼👌🏼 it was PERFECT! So proud of you Katy Brent! You smashed this book right out that park girl! If you have to wait to read until August trust me…. IT WILL BE WORTH IT!

so bittersweet finishing this book and therefore this series🥲 did not want it to end one bit!!!

absolutely LOVED finally being back with my vegan feminist serial killer diva queen kitty🩷🩷🩷🩷 and getting to know antoinette more too, she’s so unhinged i love her! loved their bond so much too

love love loved the la setting!! love the fact we’ve got the chance across the series to see kitty kill in lots of different locations, adds a lot to the excitement (and stress) and la felt like a perfect place for kitty and antoinette

very glad for the loose ends from the last book to be tied up, this was honestly the perfect ending for kitty’s story, but i’m going to miss her so much!!!

of course had everything we could want in terms of kitty’s classic kills with some chaotic energy from antoinette too, and lots of fast paced and tense moments (my watch literally told me to relax at one point because i was so stressed LOL) and lots of classic kitty / katy brent humour which we LOVE

oh kitty im going to miss you so much🥲 katy brent please give us more!! or give us an antoinette spin off!!!!🙏🏼🙏🏼🙏🏼

alllllllll the stars for this book of course, katy brent can do no wrong in my eyes <3333 my only complaint is that the series is over !!!!! i want more !!!!!!

could talk about this series and kitty collins forever, and i will recommend these books to anyone and everyone. as much as they are a comedy and unrealistic, they are a very important narration on how many awful awful men there are in this world and the fact that justice is never served and there will always be men who get away with the worst possible crimes. give me more feminist serial killers!!!!

thank you SO much to hq and netgalley for the arc, i could not be more grateful for the fact i got the chance to read this book early😭

[Dana · Rating 5 out of 5]

Kitty Collins is back, and with a vengeance! The third installment in the series is as good as ever and fans of the books are certain to love this one as much as the others. I certainly did!

I definitely think that these books should be read in order to fully appreciate the arc of Kitty's personality development over time. I am writing this with the assumption that you have read the first two, because I am including details that may spoil some of the twists and surprises in the previous books. Stop here, go read them (you will love them!), and then come back, or just go read this one too!

This story picks up immediately after where the last one ended, with Kitty and Antoinette in LA to avenge what happened to Tor before the conclusion of I Bet You'd Look Great in a Coffin. The relationship between the newly discovered half-sisters is lots of fun to watch as it develops. They get to know each other better and forge their bond through their attempts to take matters into their own hands with respect to the patriarchy and the evil men it protects. But Antoinette is a bit over-eager and sets her sights on other men besides the one who hurt Tor, causing Kitty to recalibrate her plans. Their escapades are hilarious but also very sad: women should not have to take care of the criminals who get away with their misdeeds. But rooting for the murder of bad men is the premise of this series, right?

Thanks to NetGalley, the publisher, and the author for providing a review copy in exchange for my honest opinion.

Thank you @hqstories @harpercollins @but_katy_did_it for providing me with an Advanced Reader Copy of this #gifted physical book. All opinions are mine alone.

From The Publisher:

If a man hurt your best friend – like, really hurt her – what would you do?
Key his car? Or hunt him down and chop him into little pieces? Tough decision, I know.
I’ve tracked this lowlife to LA and brought my little sister Antoinette along for the ride. I'm trying not to be irritated that she's found a taste for murder and is leaving body parts all over our hotel. Because this girls’ trip needs a Hollywood ending.
And of all the men I've killed before, this one will be the sweetest…

Thoughts:

Full stop, I’ve loved Kitty Collins since I cracked the first page in How To Kill Men And Get Away With It. I loved her even more in I Bet You’d Look Good In A Coffin. And now—I honestly don’t know how she can get any better. Think Dexter meets Finlay Donovan, and you have our girl.
This series is so dark, gritty, and downright funny, and honestly, I strive to be Kitty Collins when I grow up 😏. Katy Brent does satrical prose like no other, and I love every second of it!
I loved that Kitty had an apprentice in this book and it was fun to switch up the location.
I’m excited the ending left it open for a continuation of the series and can’t wait to read more.
Read this series now!

Thank you to both #Netgalley and Harper 360 | HQ Digital for providing me an advance copy of Katy Brent's third and final installment in the Kitty Collins series, To All the Men I've Killed Before, in exchange for an honest review.

#ToAlltheMenIveKilledBefore follows Kitty to LA where she is traveling to "wrap-up" some loose ends after the despicable actions of a certain abusive therapist hospitalizes her best friend, Tor. This time, however, Kitty has a sidekick to serve as her avenging "murder-admin assistant", her newly discovered half-sister, Antoinette. Unlike Kitty, Antoinette lacks the finesse and foresight required for their shared hobby, leaving Kitty with double the responsibilities and twice the stress to ensure the dynamic duo are not arrested. The wild adventure commences a mere two days into the trip when Kitty returns to their Bungalow to discover a maimed A-list celebrity resting at her sister's feet (literally), prompting them to book a nearby Airbnb where they encounter an interesting set of roommates already residing on the property.

I strongly recommend clearing your schedule ahead of cracking open the final installment, or saving it for a #beach day, because to quote a popular advertising slogan, "Once you pop, the fun don't stop." While surprisingly still as entertaining as the first two books, one star docked for the slightly less comedic and more outlandish plot. Overall, four solid and well-earned gold stars.

[Laura · Rating 4 out of 5]

"To All the Men I've Killed Before" is a blend of rom‑com charm, thriller tension, and perfectly timed dark humor. Honestly, it’s the ideal mix. I absolutely adore this series, but this installment might just be the best one yet. The humor is sharper, the banter is snappier, and there were moments that had me literally laughing out loud. The dynamic between the two sisters felt so natural like they have known each other their whole lives.

What really stood out in this book and series, though, is how the author tackles the impact of sexual harassment and the harm certain men inflict on women. It’s handled with a thoughtful balance—clear enough that you feel the weight of the trauma these characters carry, yet written in a way that still allows the story to be engaging, endearing, and ultimately satisfying in its outcomes.

The thriller and mystery elements were stronger this time around. Even though I had a sense of where the plot was headed, it was still incredibly enjoyable to watch it unfold. I devoured the entire thing in one sitting because I simply couldn’t put it down. A fantastic addition to the series and an absolute blast to read.

Thank you Harper 360 and NetGalley for the ARC. Thank you Katy Brent for writing this series! All opinions are my own.

[Randi Bailey · Rating 3 out of 5]

Kitty’s best friend, Tor, has been brutally attacked by her boyfriend. She was left battered and bleeding while Aiden disappeared without a trace. Determined to make him pay, Kitty Collins places Aiden at the top of her list of men who deserve to die. Her search leads her to Los Angeles where she seeks help from her unhinged sister, Antoinette, to join the hunt.

The first two books in this series were easy five-star reads for me, so I went into this one with high expectations. Unfortunately, it didn’t quite deliver the same magic. I’ve always loved Kitty’s confidence, intelligence, and calculated approach to her vigilante lifestyle, but this time everything felt much messier. The plot seemed to be pulling in too many directions at once, and Kitty herself didn’t feel quite like the character I’d grown to love.

That said, Katy Brent’s dark humor and sharp writing are still present, and I was invested enough to keep turning the pages to see how everything would unfold. While this installment wasn’t my favorite of the series, I’m still curious to see where Kitty’s story goes next.

[Chloe Reads Books · Rating 3 out of 5]

First of all, I would like to thank Harper Collins for gifting me a copy of this book in exchange for an honest review.

This book was fun! We follow the adventures of Kitty Collins who has an uncontrollable urge to kill bad men. Without spoiling the earlier books, in book three she has a new sidekick and they journey from London to LA to track down a particularly bad man.

I enjoyed the humor in this book, and I think it's particularly fun for a 'binge in a sunny day' kind of book (which is exactly what I did).

However, I didn't feel that it was the perfect storyline for me. Everything was a it quick and convenient and nonsensical at times, which made it feel a bit silly. But the humor of the whole book is a bit silly, so it worked, it just wasn't impressive-level mystery.

I appreciate the female rage, the empowerment of women to take down men, but I do feel like it was a little bit over the top. Having read in this series already, I don't feel like it needed reinforcing as much as it did in this book. While I don't dislike the message, I think with reader-intelligence it didn't need to be force-fed as much as it seemed.

[Cassie · Rating 4 out of 5]

Darling, if revenge had a frequent flyer programme, Kitty Collins would be in first class to LA. ✈️🔪

Kitty’s back — and this time she’s brought her delightfully unhinged little sister, Antoinette, along for the ride. The mission? Track down the man who left one of Kitty’s closest friends for dead. Subtle? Not quite. Satisfying? Absolutely.

Naturally, he’s not the only one who ends up on the Collins sisters’ rather… bespoke justice system. Along the way we’re treated to new friendships, a dash of romance, and that irresistible found-family warmth — all wrapped up in the gloriously dark humour we’ve come to expect.

And honestly, as wicked as it all is, slipping back into Kitty’s world feels a bit like coming home… if home were slightly murderous and impeccably well-dressed.

Many thanks to Netgalley and HarperCollins for an advanced copy in exchange for my honest opinion.

[Jessica Bradley · Rating 5 out of 5]

We were lucky enough to receive an ARC of the third book in the Kitty Collins series and it definitely did not disappoint. Picking back up with Kitty felt so effortless, like returning to the chaos of a friend whose life you know is about to spiral in the most entertaining way possible.

While I really missed the audiobook narration this time around because it added so much personality to the earlier books, the story itself still completely held up. The twists kept coming, the dark humour was as sharp as ever, and the “murdery” chaos that makes this series so addictive was still front and center. Katy Brent has such a fun way of balancing suspense with humour, and it makes these books incredibly easy to fly through.

I found myself fully invested the entire time, constantly wondering what Kitty was going to do next and how everything was possibly going to unravel. Even when things get outrageous, Kitty remains such an entertaining character to follow.

Overall, this was another solid 4-star read for me and now I’m already missing Kitty Collins. I genuinely hope this isn’t the last we see of her because I would absolutely keep reading more of this series.

[Lindsay Mildenberger · Rating 5 out of 5]

I have not read book #1 or #2. While it is absolutely not necessary to be able to enjoy book #3 I’m sad to have missed them.

Kitty and her sister Antoinette are vigilantes. Well Kitty is. And Antionette is her apprentice. They don’t kill women…well unless they have to. But they do kill a lot of men especially if they have harmed women in their past. There’s more to the story…but that’s really all you need to know. This book is so entertaining. I read it start to finish in one day by accident because I didn’t feel the need to put it down. The story is good but it doesn’t even really matter because it was written so well. Highly recommend.

Thanks NetGalley for the opportunity to read in exchange for an honest review.

[KELLY · Rating 4 out of 5]

I have read all the books in the series, and this one is the best yet! It’s wildly entertaining, darkly humorous, and completely over-the-top in the best way. The story follows two half-sisters meeting for the first time and joining forces on a revenge-fueled mission, leading to plenty of chaos, surprises, and a few well-placed twists along the way.
Fast-paced, clever, and packed with outrageous moments, this was an addictive read that kept me hooked from beginning to end. Fans of dark humor, revenge plots, and dysfunctional family dynamics are in for a treat! ⭐⭐⭐⭐

Pick up on release sate 8 / 25 / 2026.

3.5 stars
Kitty is the friend you need to exact revenge on the men who deserve it. A vegan serial killer with high morals. After Kitty's best friend Tor is assaulted by her therapist/ boyfriend, Kitty along with her sister Antoinette head to L.A. to find him and exact revenge. Kitty is determined to follow through with her plan, but Antoinette's impulsivity throws a wrench in this. Comedy ensues and while there are some twists, they are somewhat predictable. Although this is the first I've read in the series, not reading the first two did not affect my enjoyment of Katy Brent's latest Kitty Collins book.

4.25/5

Thank you Net Galley and Harper 360 for his advance copy.

What a ride this was.

This was a book I could not put down. I got through this book pretty quickly when I actually had the time to sit and read. It just flowed so well. It was humorous, had layers and it did not disappoint. I was hooked from the first page until the end.

Kitty teams up with her sister Antoinette to take out a man who put her best friend in a coma.

I actually really enjoyed Antoinette and her randomness. The iconic fake names lol idk she just seemed like a good time.

From the friendships to the crimes. Uncovering secrets as side quest, there is just so much to unpack in the best way.

[Christine · Rating 3 out of 5]

Thank you NetGalley and HarperCollins Canada for the ARC in exchange for my honest review.

2.75 ⭐️ Not gonna lie, this was a slow start for me. The premise—a vegan feminist serial killer and her sister hoping to follow in her footsteps—is great, but the execution felt a bit too caricatured, and the humor didn’t quite land. The twists were easy to spot early on, and it was hard to feel anything aside from mild annoyance towards most of the characters. Though this book had its moments, overall, I might just be a bit too millennial (see also: old) for it to really hit the mark.

[louloutereadin · Rating 4 out of 5]

Thank you to the publisher and Netgalley for letting me read this arc.
I was really excited to read this arc because of the description, and I wasn’t disappointed at all.
I really enjoyed the concept of the book and the plot. Women killing disgusting men? Yes yes and yes I’m totally in.
—> “The Collins sisters”, I really liked the #foundfamily between the main character and her sister. Not only that but we had also a bit of friendship, and also love.
It was such an easy and funny read, even tho it was a bit predictable all along, it didn’t take away the joy of reading it.

Thanks HarperCollins and NatGalley for an ARC of this book in exchange for an honest review. I absolutely love this series, and this might be my favourite book in it yet. It was totally binge-worthy, with a few fun twists as well. While these characters are not ones you should love, Brent writes them so well that I do. I finished this book in a single sitting. If you like these funny mystery/suspense novels, check this one out when it’s released at the end of August. It was a ⭐️⭐️⭐️⭐️⭐️ read for me (for this kind of genre).

I was lucky enough to get an early copy. And I could not put it down. I read it all in one evening. Being an absolute avid fan of Katy and her writing and a self proclaimed Kitty Collins super fan I can honestly say this instalment was everything I needed as a reader and more. Katy’s writing is just fabulous and the story is just as gripping as the previous two instalments of Kitty. Love love love!!!

[Britney Ireland · Rating 4 out of 5]

Absolutely enjoyed this read!

This fast-paced thriller delivers a satisfying dose of karmic justice as the people responsible for terrible acts are forced to face the consequences. The revenge-driven plot kept me turning pages, eager to see how everything would unfold. Very satisfying read!

Definitely a female Dexter vibe in this book.

Thank you #NetGalley for the ARC of this to read and review.

What a wonderful third book of this series! I wasn’t sure what to expect because sometimes books in a series can get a little worn out by book 3 but this was just as incredible as the first two. There were some twists I didn’t see coming and it was a great conclusion to series. Everything wrapped up nicely.

Katy Brent is an auto buy author for me now!

Kitty Collins is my hero! This book was just as good - and just as full of twists and laughs - as the two that came before it and I couldn't put it down.
