Meat is murder

This is a book about murder and forced labour as well as the cost of beef. And the last is quite probably the most important.
A Trade of Blood is the third book in Robert Jackson’s Bennett’s Shadow of the Leviathan series of fantasy mysteries. The books follow the duo of Ana Dolabra and Dinios Kol as they investigate politically sensitive crimes across a biohacked secondary world empire which is constantly threatened by attacks from massive, amphibious Titans from the sea (think Pacific Rim-esque kaiju). Both Ana and Din have had significant biological enhancements. Ana struggles greatly with external stimuli but is able to stitch together astonishing chains of logic when provided with appropriate information. Din, meanwhile, has been altered to have perfect, photographic memory. He investigates, observes, and reports back to Ana, who reaches conclusions with alarming rapidity.
In A Trade of Blood, Ana and Din travel away from the sharp end of the Titan threat for the first time in the series (the first two books having been set right near the sea where the Titans come ashore). They travel to the agricultural heartland of the empire to investigate the killing of the daughter of one of two key families in the beef industry by the son of the other key family. Any disruption of food supplies would seriously upset the stability of the Empire, and thus Ana and Din, specialist Imperial Iudex (the judicial/police/investigative branch of government), are sent to try to resolve the matter with a minimum of fuss. The facts of the killing seem largely indisputable, but the victim doesn’t remain the only dead body for long, and things get a little bit more complicated than they first appear, leading into a well-crafted, engaging mystery. I picked the culprit a bit earlier in this book than in the earlier ones, but it all still, in my view, worked very well.
As with previous books in the series, Ana and Din are very much our core cast, and their dynamic is fantastic. Ana is salty and waspish, and has absolutely no filter. Din, in contrast, is the straight man, sighing along, but also giving his own deadpan ripostes. This is established from the very start of the book, which opens thus:
“IT IS AN INARGUABLE TRUTH, you know,” said Ana, “that most people are absolutely enthralled by dead girls.”
I cracked my eyes and gazed at the carriage ceiling, certain I’d misheard this comment. I waited, listening to the rumble of the wheels and the crackling of the horses’ hooves on the gravel road.
Perhaps she would stop now, I thought. Perhaps there would be no more of it.
I shut my eyes and sought my way back to sleep.
“In fact, did you know, Din …” said Ana.
I opened them again.
It’s a genuinely funny dynamic, but it’s also great character work; the general banter and occasional seriousness and sincerity make it clear that these two, three books and a year or so into their working relationship, like and respect each other. Both also have ongoing, though low-key, plot threads that carry through from earlier books, Ana relating to what exactly her modifications are and Din to a quite difficult family history (these do mean that the book doesn’t entirely stand alone—though you can certainly enjoy a significant majority of what’s going on in the book without having read the first two, you would be missing enjoyable context if you did so).
The interchanging support cast is also (as it was in the first two books) very well done. This ranges from various family members of the victim and the accused to local law enforcement and, most prominently, the leader of the local Orbiis corps—essentially agricultural bioengineering specialists. Din also has a family connection pop up in a quite unexpected fashion. I also enjoyed very much that Bennett continues to present Din as that exceptionally rare beast in SFF, the bisexual man who generally prefers men, and the use of that aspect of his character (and his eidetic memory) to play with the “love interest of the week” dynamic one often gets in noir fiction is well judged.
This is the point at which mystery reviewing gets a touch difficult, at least for me. I find it quite difficult reviewing in this genre—at least before release—because you can't go into that many plot- or character-specific specifics without spoiling the whole thing. In most cases spoilers aren’t something I care about, but they really do matter for most mysteries, and that that is indeed the case here. However, the fact that it is a fantasy mystery means that isn’t all there is to talk about—the worldbuilding and thematic concerns hanging off the mystery plot also reward attention. RJB is very clear that what he's doing with this series (aside from writing deeply entertaining Nero Wolfe pastiches) is examining the different institutions of a society designed and tuned to address an ongoing, existential environmental threat. In Ana & Din's world this is the annual march of the Titans inland from the sea (as noted above, these are major presences in the first two books, absent in all but the use of their body parts and excretions as essential elements of Imperial biohacking here). But the story is also very clearly holding a mirror up to our world and the ongoing, existential threat of environmental degradation, particularly climate change.
As I've written elsewhere, there is a distinct genius to the nature of the role Bennett gives Ana and Din as specialist Imperial Iudex. They're not private detectives. They're not CSI technicians. They're not even really cops. They are Ombudsmen (in the European sense of the term of an organisation to investigate and ensure integrity in government). It's not a perfect analogy—there's rather more violence and crime scenes than Ombuds in the real world typically deal with—but at heart the crimes and puzzles Ana and Din investigate go to the proper functioning of the Empire's government. That proper functioning, it is made very clear, is maintaining social stability and directing that stable society at the eternal problem of staying alive with a decent standard of living in the face of centuries of rampaging kaiju. This setup allows our main characters—and Bennett—to poke around in all of the key institutions that make society tick. The Tainted Cup was engineering/civil works. A Drop of Corruption was basic forms of government and international relations. And A Trade of Blood is agriculture and food production.
It might seem weird to say this is part of government, but there's an Imperial bureaucracy responsible for agriculture too, complete with genetic enhancements: the aforementioned Orbiis. And food production is of course critically important to social stability; there’s a reason Juvenal sneered about “bread and circuses” as a mechanism for keeping the plebs happy almost 2,000 years ago. That sneer is particularly true of raising beef, which ultimately is an unnecessary luxury in land use and nutritional terms. But it's delicious, people want it, it keeps them happy, and happy people are easier to direct at the existential problem. But raising beef in this world is also wildly, weirdly artificial: biohacked giant tottering cattle with tonnes of meat on each limb, pre-sapient cat-monkey things pressed into service as field hands, and perfectly tuned magic fertilizer. We also see the waste: enormous piles of bones and hides. In reality that would very likely be used for something, but Bennett is clearly going for a 'slaughter of the buffalo' style image here, and it's an effective one. If he isn't going full militant vegan (and I think the book's take on the role of food as a social stabiliser is too pragmatic for it to go that far), he's clearly interested in showing the desensitisation to death that the factory beef farming methods cause.
The point Bennett is making, of course, is that this is all pretty much all true of how agriculture works in our world too, at least on a mass scale as it is practiced in most developed countries to a greater or lesser extent. Exploring these ideas in a secondary world gets the familiar context out of the way so we can see the strangeness in what we accept as quite normal in our own society. As Bennett states in his author's note, despite agriculture being framed in much of our current political discourse as a “natural” sphere set against the unnatural cities, there is little we do that is more profoundly “unnatural” than industrial farming. In this shock of recognition amidst the alienating oddity of Ana and Din's biohacked world, Bennett asks us how far we will have to hack ourselves and our society to survive what's coming from our planet and what the costs might be. Having these questions consistently in the background throughout a well crafted, taut mystery, excellent character work, and engaging worldbuilding really is impressive. It's rare that a novel this much sheer fun is also so thought-provoking. Another excellent entry in a series of remarkably consistent and remarkably high quality.
Highlights:
- Engaging fantasy mystery
- A hugely compelling core duo
