Robert Jackson Bennett continues to shine brightly with the epic second novel in his Shadow of the Leviathan series, A Drop of Corruption, an exceptional and incredible fantasy murder mystery that I could not get enough of.

Robert Jackson Bennett is an awesome author who has produced some impressive fantasy series over the last few years.  Best known for his Divine Cities and Founders trilogies, Bennett has consistently wowed audiences with his elaborate settings, great characters and intricate narratives.  However, even though I knew how good an author Bennett was, I honestly was not prepared for how much I would enjoy his 2024 novel, The Tainted Cup.

The Tainted Cup was a truly outstanding novel that saw Bennett bring together the fantasy and murder mystery genres into an exceptional and highly addictive fusion.  The first book in the author’s Shadow of the Leviathan series, The Tainted Cup followed the young assistant to an unnaturally gifted investigator as they attempted to solve several murders brought about by magical grass.  Set in a powerful Empire constantly under attack from giant leviathans, The Tainted Cup was a truly epic read, and I loved the elaborate narrative that emerged, as Bennett perfectly set a highly clever mystery amongst the chaotic and highly detailed fantasy setting.  The result was a five-star novel that ended up being one of my favourite books of 2024.  I really cannot emphasise enough just how good The Tainted Cup was, and I think it goes without saying that I was very keen to continue the series after that outstanding first entry.  As such, the second Shadow of the Leviathan novel, A Drop of Corruption, was one of my most anticipated books of this year, and it really did not disappoint.

On the borders of the Empire of Khanum lies the small canton of Yarrowdale, part of an independent kingdom that is reluctantly set to join the Empire.  A dank and impoverished land filled with swamps and waterways, the only thing of importance for the Empire in Yarrowdale is the high-security compound known as the Shroud.  A top-secret lab where the best scientists from the Empire dissect fallen leviathans to harvest the transformative magic found in their blood, the Shroud keeps Yarrowdale on the map and its inclusion in the Empire an inevitability.  However, when an impossible crime takes place within its borders, all eyes within the Empire will be looking towards it.

An important Imperial Treasury officer on assignment to Yarrowdale has gone missing, seemingly disappearing into thin air inside his locked and guarded quarters.  Needing answers, the Empire calls upon its most unlikely hero, the brilliant, and possibly insane, special investigator Ana Dolabra.  Accompanied by her loyal and often exasperated assistant, Dinios Kol, Ana soon invokes her uncanny talent for observations and ability to make unlikely connections to find answers.  But despite quickly working out how the victim disappeared, Ana discerns that the crime was only the first move in a diabolical master plan.

A dangerous and clever killer is stalking Yarrowdale, one with the ability to think ten steps ahead and effortlessly cover their tracks.  Worse, the killer has devious designs on the Shroud and is willing to use the facilities own dark science against it, crippling the Empire’s ability to defend itself.  To save the Empire, Ana and Din will need to discern the killer’s schemes and stop them before it is too late.  But have the pair finally met an opponent even more brilliant that Ana?

Wow, wow, wow, now that was an outstanding book!  Robert Jackson Bennett once again impresses to the extreme as A Drop of Corruption was an incredible read that I honestly could not put down.  Another excellent blend of brilliant mystery and inventive fantasy fiction, A Drop of Corruption was so damn good, and I loved every single second I spent absorbed in its captivating pages.  A very easy five-star read and one of the very best fantasy novels of 2025.

I just loved the story Bennett cooked up for A Drop of Corruption, and frankly I am still thinking about its many elaborate twists, turns and revelations.  Starting off with a good introduction to Yarrowdale, a setting starkly different to the locations from the previous book, the reader is soon brought up to speed about the unusual case within the isolated canton.  Told exclusively from the perspective of assistant investigator Dinios Kol, you soon become emmeshed in finding out how the treasury official disappeared from his guarded room, with his body soon discovered in the nearby waterways.  Thanks to the combination of Kol’s enhanced memory and the unique mind of lead investigator Ana Dolabra, the manner of the victim’s disappearance becomes apparent; however, this only raises more questions and reveals a dangerous killer stalking the canton.

Now I guarantee that at this point of the story you will be extremely hooked, thanks to the compelling mystery that is developing, as well as the intriguing characters, cool new setting and the hints of a very clever killer capable of outthinking the protagonists.  Following some cool moments that indicate just how far the killer is willing to go to achieve their goals, Bennett cleverly ties his mystery into some of the fantastic elements of the setting, including Yarrowdale politics, and the hidden science of the Apothetikal, the branch of the Empire dedicated to the biological alchemy that enhances people.  The author really raises the stakes as the book continues, especially with dangerous bioweapons, essential scientific advances, and ancient political turmoil all impacting the plot.  Bennett keeps the shocks going with several impressive scenes, especially the killer works to alter the destiny of both Yarrowdale and the Empire.

This leads up to the very exciting and fast-paced final third of the book, where all the pieces of the mystery come together.  Despite knowing the identity of their opponent, the protagonists are forced to work overtime to try and catch them as they constantly stay multiple steps ahead of them.  The protagonists are soon forced to take drastic action to get answers, and there are some great scenes as some interesting revelations come to light and various characters are forced to face the consequences of their actions.  After a particularly powerful scene that hints at dark secrets that will likely become a bigger problem later in the series, Bennett masterfully builds up to the final confrontation, where Ana provides her final deductions, and chaos reigns as a result.  This entire conclusion was so damn clever, and it was very satisfying to see Ana bring all the story threads and hidden elements of the mystery together in the climatic revelation scene.   This all results in a thoughtful, moving but overall satisfying end to the book that perfectly wraps everything up, and allows the series to continue.  Readers are guaranteed to come away from A Drop of Corruption very happy, and I know that I am even more eager to continue this series after this exceptional second outing.

As with the first Shadow of the Leviathan novel, A Drop of Corruption was an outstanding and captivating blend of fantasy and murder mystery storytelling elements, as Bennett wraps a particularly impressive investigation narrative around a distinctive fantasy setting.  In many ways an over-the-top fantasy Sherlock Holmes novel, A Drop of Corruption was so damn addictive, with no slow moments as the protagonists follow a deadly trail of a dangerous and unnatural killer.  The mystery itself is just perfect, and I loved how well the author enhanced the elaborate investigation with his own unique fantasy elements, carefully blending them together to create and even more elaborate tale.  Thanks to the constant revelations, carefully hidden clues, sudden outrageous twists and some very entertaining characters, I honestly found myself unable to put this book down, as I couldn’t wait to see what amazing reveal was coming next.  Bennett also successfully balanced the darker tone of the narrative with his own excellent character-driven humour, which ensured some lighter moments amongst the serious investigation and dangerous results.  This humour, which mostly lay around the author’s outrageous detective protagonist, often had me chuckling out loud, while never overpowering the murder mystery or fantasy elements.  Working well as either a standalone novel or a sequel to The Tainted Cup, there is something very fun for everyone in this book, and all fans of either fantasy or crime fiction can have a brilliant time here.

In addition to featuring a cool story with some wonderful blended elements, A Drop of Corruption also served as a great expansion of the outstanding fantasy realm introduced in The Tainted Cup.  I personally loved the overarching setting of the Empire of Khanum, which not only features gigantic, mutated monsters constantly attacking its walls from the sea, but also features a unique magical system of biological grafts originating from leviathan blood that alters people, animals and plants to benefit the Empire.  Many of these unique elements are on full display in A Drop of Corruption, with the focus on new grafts, research into the leviathans, and the existing enhancements of the protagonists all serving as key plot points in the main mystery.  Highlights include dangerous bio-weapons, grafts that turn the antagonist into a particularly dangerous opponent, and an elaborate look inside the research station known as the Shroud.  These unique fantasy elements are well re-introduced and expanded on as the novel continues and allowed for quite a unique crime fiction read as they are cleverly inserted into the plot.

Bennett also uses this book to explore new areas of his fantasy setting, particularly by introducing Yarrowdale, a semi-autonomous nation under the Empire’s influence that has yet to officially join it.  Filled with its own people, politics and history, as well as the influence of the Apothetikal, who have one of their most important bases there, Yarrowdale is a very different place to the previous settings featured in The Tainted Cup, and Bennett paints an elaborate picture of swamps, waterways and disgruntled locals who have their own opinions about joining the Empire.  As with the existing fantasy and setting elements of the book, Bennett expertly introduces and utilises this new setting into his narrative, and it serves as an effective and compelling background to the plot, especially when the case gets even more complicated, and the protagonists are forced to become involved in Yarrowdale politics and its royal family.  These scenes also allow Bennett to engage in a bit of social commentary, especially when it comes to the overall wickedness of kings (or other autocratic rulers), and it was fascinating to read his notes at the end where he expands on some of these points.  I really enjoyed this complex additional world building from Bennett, especially with how well it was utilised in the main story, and every new glimpse of the Empire of Khanum makes me an even bigger fan of this series.

I must also highlight the two awesome main protagonists that helped to make A Drop of Corruption so impressive, as Dinios Kol and Ana Dolabra were a highly entertaining duo.  Featuring an often exasperated but loyal subordinate working for a brilliant and eccentric detective, Bennett once again achieves the iconic detective/sidekick dynamic that fans of Sherlock Holmes will be familiar with.  In this case, Dinios serves the Watson role as the book’s only point of view, which allows him to be the sounding board for the mad detective, in this case Ana, while also being present for all of her deductions.  As such the reader, through Dinios’ eyes and ears, get the full explanation for how Ana reached her conclusion as she brings her assistant up to date.

This method of splitting the load between the detective and the sidekick is a classic for a reason, and I loved seeing the compelling story emerge from Dinios’s perspective, as he was front and centre for all the case’s twists and turns.  He was also a witness to all the crazy behaviour of his boss, and Ana did not disappoint, being her usual disrespectful and slightly unhinged self.  Most of the book’s humour came from Ana’s insane behaviour and the reactions of the other characters seeing it, which, alongside her incredible detective skills, is quickly making her one of my favourite fictional detectives.  I really enjoyed the dynamic that continued in this sequel novel between Dinios and Ana, and you get a great balance of eccentric genius and troubled young apprentice throughout the story.  While this partnership hits some snags in this book, especially as Dinios dreams of a more heroic career while Ana proves to be her usual impossible self, it proves to be a strong centre to the book, especially as certain revelations bring them even closer together.  A truly incredible central pair of protagonists whose entertaining antics I could not get enough of.  Throw in a great selection of supporting characters, including an intelligent and enhanced local assistant who manages to out-sass the protagonist, a multitude of suspicious individuals who have their own secrets around Yarrowdale, and an antagonist who is built up to be an insanely intelligent opponent for the protagonists, and this really ends up being an exceptional, character focused novel with some real emotional heart to it.

Overall, A Drop of Corruption was another exceptional novel from Robert Jackson Bennett, who did a truly outstanding job continuing his Shadow of the Leviathan series.  A Drop of Corruption was so damn good, and I loved every single part of this epic fantasy and crime fiction hybrid.  I honestly cannot recommend this book enough, and it easily one of the top fantasy reads of the year.
