On Sunday I finished The Tainted Cup, the first book in the Shadow of the Leviathan series by Robert Jackson Bennett. This is a fantasy murder mystery with an element of political thriller.

The main character is Ana Dolabra, an eccentric but brilliant investigator, and I believe this is the first time I’ve ever seen a woman fill this role. The wacky but effective investigator is of course a very well-known stock character, but has always been, in my experience, a man. I found Ana delightful; strange but not off-putting, and without coming off like the author was working to hard to make her quirky.

However, our point-of-view protagonist is Din Kol, Ana’s put-upon assistant, on whose shoulders falls the managing of her many idiosyncrasies. They’re a fun team to watch work, and in this first book we get to see their working relationship unfold, as they’ve only recently teamed up at the start. Din is fine, but mostly I appreciated him as a lens for Ana.

Bennett’s fantasy world is characterized by fantastical use and manipulation of plants and the human body. Din, for instance, has been modified to be an “engraver”—someone with an eidetic memory. For obvious reasons, this serves him well as aid to an investigator.

I think Bennett does a good job of throwing you into the world and letting you use context to figure most of it out. I get bored with SFF novels that feel the need to hold your hand, as if you might be a first-time SFF reader who never encountered a magic system before, so I was relieved when Bennett just started telling the story and letting me figure the world out as it went along. I’d rather be a bit lost at times than be toddled along, but I never felt lost here.

The novel touches on some things that I feel are pretty keenly relevant, like the ability of the wealthy to avoid justice and their willingness to inflict suffering on the rest of society to better their own position (and then justify it to themselves).

I don’t read a ton of murder mysteries, so I may not be the best judge of this, but I also felt that Ana worked well. It’s a tough trick writing a character who’s meant to be much smarter than the rest of the cast (perhaps even than the author!), and it can fail a couple of ways: the supposed “brilliant” deductions are obvious to the average reader, making the rest of the cast look painfully dull for not seeing them; or the machinations are so obtuse with so little evidence the reader simply won’t believe the detective could have figured that out without an ass-pull from the author. I didn’t think Bennett fell into either of these traps and every detail Ana referred to in one of her deductions was something that had been mentioned before.

I enjoyed this book and I plan to read the next one. Very interested to see where Ana’s adventures take her next!
