My Rating: 4.75 out of 5 stars
The most relatable new Australian crime book for all office drones is the awesome and addictive Kill Your Boss by the always impressive Jack Heath, an exceptional read that proves very hard to put down.
There are a lot of talented and entertaining Australian authors writing outstanding novels these days, but one of my favourites due to his consistently clever and entertaining reads is the wonderful Jack Heath. Hailing from my home city of Canberra, Heath has been entertaining Australian readers for years with his interesting combination of complex works. I am a massive fan of his amazing crime fiction novels, which includes his spectacularly over-the-top Hangman series (including Hideout and Headcase).
In recent years, some of Heath’s best work has been some amazing and twisted murder mysteries set in small-town Australia. The series started with Kill Your Brother (one of my favourite Australian novels of 2021), a clever read that saw a damaged protagonist imprisoned and forced to choose between killing her guilty brother or dying alongside him. I had an outstanding time with Kill Your Brother, and I eagerly dove into the loosely connected sequel, Kill Your Husbands. Featuring two of the protagonists from Kill Your Brother as they get drawn into a devastating case involving a series of murders after some ill-advised partner-swapping. I deeply enjoyed this fantastic sequel, and it ended up being one of my favourite Australian books of 2023. Naturally I was very keen when I saw that Heath had a third book in this series coming out in late 2025 with the awesome title of Kill Your Boss. I dove into Kill Your Boss as soon as I could, and it proved to be another great read with a very fun plot behind it.
Plot Synopsis:
What would it take to turn you into a killer?
Detective Sergeant Kiara Lui has just broken up a loud brawl between two blokes in front of the Warrigal Public Library. But just as she’s about to leave the scene, a man inexplicably plummets from the sky and slams into the bike rack right in front of her, dead.
Neville Adams was the head of library services, hated by staff, borrowers, or in fact anybody who had ever met him. Kiara quickly seals the building, trapping everyone who might have pushed him off the roof. She expects to have someone in custody within minutes.
Instead, the investigation becomes the most challenging and dangerous of her career as it spirals outward, ensnaring half the town. It seems that Neville was connected to the disappearance of Emmylou Chisholm – a case that Kiara could never solve, and that has haunted her ever since.
If the killer isn’t found fast, the first two victims won’t be the last . . .
Compelling, propulsive and darkly funny, this is a perfect follow-up to Jack Heath’s bestselling Kill Your Husbands.
Kill Your Boss was a particularly amazing novel from Jack Heath and one of the better pieces of Australian fiction I had the pleasure of reading in 2025. Featuring an extremely compelling crime fiction narrative with some fantastic dark humour behind it, Kill Your Boss was extremely fun to get through, and I had a brilliant time with this latest twisted offering from Heath.
Heath cleverly builds around the fantastic and entertaining concept of a villainous and wildly disliked boss getting murdered. Once again set in the small Australian town of Warrigal, Kill Your Boss has an instantly great opening with the victim, Neville Adams, plummeting to the ground from the library roof, right in front of main police protagonist Detective Sergeant Kiara Lui. Kiara, who previously served as a supporting character in Kill Your Brother and the main investigator of Kill Your Husbands, quickly takes charge of the case, locking down the library and hoping to identify the killer amongst the people trapped inside. However, Kiara soon hits a wall with her investigation when it becomes apparent that everyone in the library, especially Adams’s employees, hated him. With multiple motives and no witnesses, Kiara starts diving into the crime, assisted by rookie cop Ben Higgens.
This first part of Kill Your Boss sets the story up nicely, and you are soon quite hooked on the case, especially as the novel breaks apart to follow either the police or one of the suspects. Thanks to this split, you get a good insight into the compelling investigation, while also examining the combined motives of the potential suspects, each of whom are covering something up, including involvement in an alternate case that the protagonist is familiar with. Heath keeps the story moving quickly and effectively, and there is some additional grim humour as it becomes apparent that multiple characters tried to kill Adams, but only one succeeded. This perfectly leads up to the final third of Kill Your Boss, as all the various motives come to light, and the various suspects are whittled down thanks to some additional gruesome killings before the big conclusion. I think that Heath set up this entire mystery extremely well, and the various red herrings ensured you were guessing right up to the end.
Heath once again manages to pull together a brilliant book that is somehow fun and twisted at the same time. Featuring a series of murders that starts with a very relatable sentiment around bad bosses, Kill Your Boss effectively builds up a complex mystery that has a lot of fantastic layers to it. This mystery is then well supported by the author’s great use of multiple different perspectives, especially as you get invested in all the complex suspects and their lives. This tight and entertaining story hits hard while also presenting the reader with dark humour, especially when it comes to motives for murder, and the result is a particularly addictive book that you can’t turn away from. Heath also successfully endeavours to make Kill Your Boss a particularly open book to all sorts of readers, from those looking for an amusing Australian mystery with a great small-town setting, to those readers already familiar with the author’s wicked humour and aptitude for murder.
While part of a larger series that started with Kill Your Brother, Kill Your Boss is primarily a standalone read, which I honestly think enhances the story, as the various new characters, as well as the existing protagonist, get a lot more prominence without tying the narrative down to previous events. Detective Sergeant Kiara Lui once again works extremely well as the book’s primary investigator, and it was interesting to see her take more of a leading role in this novel. While Kiara was an excellent primary protagonist, as well as a mentor to a new police character, it is the other larger-than-life supporting characters who make Kill Your Boss very impressive. This includes a truly despicable murder victim whom you honestly don’t feel too sympathetic to, especially after the flashbacks. This excellent use of a villainous victim adds some great complexity to the plot, especially when it’s revealed that multiple people tried to kill him simultaneously. This victim is well matched by the various suspects, who serve as supporting perspective characters in the plot. Without giving too much away, each of the suspects in this novel is very entertaining, and the range of complex interactions and grudges they held made for a very entertaining read. I particularly enjoyed the final revelation about why the main killer committed the first murder, which fits the overall entertaining mood of Kill Your Boss perfectly, and was a perfect endcap on these outstanding characters.
Jack Heath continues to showcase why he is one of Australia’s most entertaining crime fiction authors. Featuring a brilliant plot loaded with outrageous revelations and supporting characters, Kill Your Boss was a wonderfully addictive novel from start to finish. Compelling, twisted and just so much fun, Kill Your Boss is a very impressive read, and it was easily one of the top Australian novels of 2025.
