Everything You Need to Know About The Tainted Cup
In the Empire of Khanum, enormous sea walls hold back the leviathans that come out of the ocean every wet season, and every institution inside those walls is organized around that fact. When an imperial officer dies in a wealthy family's home with a tree growing out of his body, Dinios Kol is sent to look at it. Din is an engraver, biologically altered so that he remembers perfectly everything he sees, which is the entire reason he is useful to Ana Dolabra. Ana is the investigator: brilliant, rude, blindfolded most of the time and unwilling to leave her house if she can avoid it. She works the case through Din's memory. One poisoning opens into contract fraud, engineered biology and the question of whether the walls will hold at all. Holmes and Watson in a body horror empire, and the mystery plays fair, the clues are all on the page.
Bennett builds mystery with architecture. The world is vast but specific, the walls feel real, and the stakes are both personal and existential. Ana is fantastic, brilliant, eccentric, prickly, capable. Her relationship with Din develops organically, grounded in character rather than plot convenience. The magic system is subtle; the mystery is front and center. You'll love the procedural elements, the slow reveal of the world's true nature, and a protagonist who doesn't need saving.

Book one of the Shadow of the Leviathan series. The central case is fully solved here, so it satisfies on its own, while the larger questions about the leviathans and the empire's rot stay open for later books.
