Review: The Tainted Cup, by Robert Jackson Bennet

In Daretana’s most opulent mansion, a high Imperial officer lies dead — killed, to all appearances, when a tree spontaneously erupted from his body. Even in this canton at the borders of the Empire, where contagions abound and the blood of the Leviathans works strange magical changes, it’s a death at once terrifying and impossible. Called in to investigate this mystery is Ana Dolabra, an investigator whose reputation for brilliance is matched only by her eccentricities.
At her side is her new assistant, Dinios Kol. Din is an engraver, magically altered to possess a perfect memory. His job is to observe and report, and act as his superior’s eyes and ears--quite literally, in this case, as among Ana’s quirks are her insistence on wearing a blindfold at all times, and her refusal to step outside the walls of her home. Din is most perplexed by Ana’s ravenous appetite for information and her mind’s frenzied leaps—not to mention her cheerful disregard for propriety and the apparent joy she takes in scandalizing her young counterpart. Yet as the case unfolds and Ana makes one startling deduction after the next, he finds it hard to deny that she is, indeed, the Empire’s greatest detective.

"Civilization is often a task that is only barely managed."

Robert Jackson Bennet's The Tainted Cup is an excellent murder mystery wrapped in the beautiful package of an immaculate worldbuilding, featuring an autistic investigator and her dyslexic assistant, who is our only narrator. This Watsonian figure is thus often as clueless as we are to the investigator's sharp deductions, and it's a delight to be there for the ride, desperately trying to keep up.

This really feels like much more of a mystery novel than a fantasy story, but I have an inkling that there will be a larger plot to unravel about the world. In this first book, the world is more in the background, but we are immersed in it with deft, precise, and small strokes. This is a world where people are artificially augmented in order to cover various tasks, where an empire built walls in order to protect the population from giant creatures called leviathans whose arrival by sea is heralded by earthquakes. This vividly painted world is teeming with contagions that scare the population, while the government is in a power struggle with powerful families. The books thus touches upon themes of classism and social injustice, and it's certain to delve more on them in the rest of the trilogy.

The interactions between Din and Ana are naturally an highlight of the book, with Din's inexperience playing well against Ana's greatness. He's not one to be intimidated, though, and he ends up being of great help thanks to his general stubborness. The rest of the cast is very vibrant, with many support characters who all feel very distinct and have their own development, following the big revelations coming from the investigation. There's even time for the sweet first steps of an achillean relationship between Din and another character, but it's not a focus.

The Tainted Cup is a great first installment.
