Robert Jackson Bennett won the 2025 Hugo Award for Best Novel with his fantasy/mystery mashup The Tainted Cup, which introduced the world to Ana and Din, an eccentric (to put it very mildly) detective duo who operate in a world that combines medieval trappings with an alternate science built around biohacking and the exploitation of massive and deadly sea creatures called leviathans. The story was solid, if a little more convoluted than that of the typical mystery novel, while the two main characters were the novel’s biggest strength, and the setting was innovative and curious enough to make me want to spend more time within it.
Bennett has written two more novels in the series already, the second of which, 2025’s A Drop of Corruption, was nominated for this year’s Hugo, losing out to The Everlasting. As in the first book, we have Ana and Din working to solve a murder that is hard to fathom and that will ultimately expose a broader conspiracy of graft, betrayal, and, of course, corruption. Set in the neighboring kingdom of Yarrow, which Ana and Din’s native empire Khanum will be taking over in an arrangement that sounds similar to the transfer of power in Hong Kong, the book goes deeper into the weird science that powers this fictional world, and the very bizarre ‘enhancements’ people within it use to do this difficult work.
Ana is the Sherlock Holmes/Nero Wolfe here, a savant who is nearly always blindfolded because she says the visual stimuli of the world are too much for her senses to handle. Din is her faithful assistant, more sagacious than Dr. Watson and more serious than Archie Goodwin, and has himself been enhanced as an engraver who can record things he sees in his mind, as if he had an eidetic memory. Their partnership, awkward and tentative for most of the first book, is more solid and more fluid here, so we step almost directly into their work to solve the first murder – which, mild spoiler here, gets solved far sooner than you might expect because of the way it expands outward into a larger story.
Again, the characters are the real thing here, although in this book Bennett has dropped more clues that might help readers piece together the ultimate solution. (The intermediate one I just mentioned isn’t solvable in that way.) Din gets more screen time than Ana, and it helps flesh out his character more, although if you jumped right to this book without reading the first, you might think Ana is two-dimensional and a bit of comic relief when her oddness is inherent to her character. One of the new characters introduced here, Malo, who has an enhanced olfactory sense, is a strong comic foil for Din, and balances his overly serious manner with her sarcasm.
The setting was what really sucked me into A Drop of Corruption. I’ve played a handful of role-playing games, almost entirely computer ones with a little D&D and its ilk in high school, and I would absolutely play the hell out of a roleplaying game set in this world – especially Yarrow, which is richer and stranger and more foreboding than even Khanum, with political intrigue and what sounds like a massive grey-market economy, along with a people hostile to almost any stranger. Fantasy novels almost always seem to involve magic on some level; Bennett replaces that with his science, which involves the use of plants and fungi to alter people and even create buildings along with the chemical enhancements that many of these characters have undergone. It’s highly imaginative, yet also coherent enough to work with the story rather than detracting from it.
The story is overlong, but the core mystery and its resolution are tighter than that of the first novel, and there are definitely more clues to catch if you’re that sort of reader. (I wish I was, but I am not.) The first murder is a locked-door mystery, part homage, part parody, and that’s about the only thing I sort of figured out here – how it was done, but not who did it. Bennett’s ambition in his plotting works for and against him, making the narrative broader and more interesting, but resulting a book that’s quite long for the genre. I’ve read a few hundred mystery novels by myriad authors and have read very few of this length, mainly by Anthony Horowitz in some of his novel-within-a-novel works. I was pulled through the book quickly – it’s 450 pages and I read it inside of six days – as much because of the characters as my desire to find the solution to the story.
Bennett also slips in a little social commentary here that the first novel lacked, some obvious (hey, slavery is bad!), but some more timely, such as Din’s family story that serves as a metaphor for the crushing pattern of medical debt in the U.S., and the main plot’s exploration of what happens in a world without regulations. Yarrow is an absolute monarchy, but Khanum is also an autocracy, and Bennett should continue to explore what that means for his main characters, who, for now at least, serve its emperor.
I will confess I’m glad to see the next book in the series, A Trade of Blood, came in under 400 pages. I’m a fan, and would have read the third book regardless, but I’ll be happy to see Ana and Din get to the point a little more expeditiously. As for this year’s Hugo, I’m fine with this book being on the shortlist but not the winner; it’s not as good as The Incandescent or The Everlasting but I’d probably put it ahead of Death of the Author.
Next up: A book off the Hugo longlist, There Is No Antimemetics Division, by Sam Hughes, who writes under the pen name qntm.
