Robert Jackson Bennett has done it again. A Drop of Corruption takes everything that made The Tainted Cup great (impossible murders, weird biology, razor-sharp wit) and somehow makes it even better. There’s a new impossible crime, more unsettling biology, and, most importantly, more Ana Dolabra - the world’s strangest mind. 

This time around, Ana and her long-suffering assistant Dinios Kol are sent to the empire’s edges to investigate a treasury officer’s disappearance. And let me tell you - it’s a gruesome murder, because if there’s one thing Bennett knows how to do, it’s making sure every crime scene sticks in your brain. This one involves dismemberment, vanished body parts, and a killer who seems to walk through walls. 

Ana solves the surface-level mystery in about five minutes, but the deeper they dig, the more tangled the case becomes. The stakes turn shockingly high. If they fail, the entire empire could collapse, and leave the world defenseless against the leviathans. No pressure. Someone out there is playing a game Ana isn’t used to losing, and Din finds himself torn between his duty as her “engraver” and his growing realization that being an investigator might not be the life he truly wants.

Now, for me the series works because we follow a brilliant and fascinating character (Ana) through the eyes of a much more bland one (Din). Din is to Ana what Watson was to Sherlock - a trusted assistant with some personality but not enough charisma to carry the series. A Drop of Corruption gives us glimpses into Ana’s past and hints at what she truly is. She’s still an enigma, but things get much clearer and much more exciting. Din, meanwhile, starts questioning his place in all of this. He signed up to be Ana’s eyes and ears to pay off his father’s debts, but as he gets drawn deeper into the empire’s ugly truths, he starts to wonder if he should be fighting to save it or choose a simpler and more profitable path.

The world-building continues to impress and remains one of the most inventive things I’ve ever read. The concept of Leviathans and the horrifying ways in which their blood transforms environment is cool. Then we have the Shroud - a living, organic space with peculiar properties. And the new characters fit right into this strange, unsettling world. Mala, for example, has an enhanced sense of smell (and more), which makes her an excellent investigator but also means she’s experiencing reality in ways that most people can’t understand.

Since Bennett doesn’t do one-note villains, the antagonist is ruthless, brilliant, and broken. Their backstory is a slow-burn tragedy that creeps up on you. If I had to nitpick, I’d say that the book is sometimes too detailed and repetitive in the middle. But honestly, when the writing is this good, why would I want to nitpick?

Ultimately, I’m satisfied, impressed, and desperately hoping we get another one in the series. Because if Bennett keeps building on this foundation, we might just be looking at one of the best fantasy mystery series of the decade.
