A Drop of Corruption by Robert Jackson Bennett

At the borders of the empire, contagions are abundant, and leviathans threaten the outer rings. The blood of those same leviathans is a key ingredient in magically transforming people to grant powerful abilities. Dinios “Din” Kol is one of those fortunate enough to have been altered. Due to his extremely enhanced memory skills, he has become an “engraver” and these skills are perfect in his role as assistant to Ana Dolabra, perhaps, the greatest living detective. And now, once again, the pair of them have been called in to solve what seems at first to be a straight-forward locked-room murder mystery.

As a sequel to “The Tainted Cup”, the first book in this “Shadow of Leviathan” series, this novel is simply amazing. Oftentimes, it seems to me, the second book in a series can be a letdown, especially if the first book was really good. But I am here to say any such fears with this author’s work have proven, once again, unfounded. In fact, this one gives us more in all respects. More plot, more character development, and much more world-building but in a way that doesn’t beat the reader over the head but rather lets it unfold as necessary to round out the various settings.

While Ana brings her genius for detective sleuthing, she is also an eccentric who prefers to wear a blindfold most of the time so as to not let her vision interrupt her thinking. Din’s perfect memory is ideal for interrogating suspects and witnesses and is able to “play-back” the facts verbatim if required. Useful in discovering discrepancies, to be sure. The murder mystery is off and running, but soon grows to something much more epic.

Author Robert Jackson Bennett has proven many times before that he is a master at building original fantasy worlds, demonstrating in-depth world-building with all the trappings you’d hope for. This is a rich world, with unusual circumstances, cultures, and motivations.

Many reviewers compare the mystery elements of these novels to a Sherlock Holmes/Watson experience, but I think a much better analogy are the works of Rex Stout. Here, Din is the fact finder, the one who goes out and about gathering evidence much like Archie Goodwin. We get most of the story from his perspective. Ana, like Nero Wolfe, largely remains behind and waits for the information to come in where she then analyzes, deduces, and brings her genius to bear.

The entire novel moves along swiftly as the original murder case grows to something affecting most of the known world. I loved discovering new abilities in other characters, engineered enhancements that I shall not divulge for fear of spoilers. This is “smart” fantasy to be sure, neither a D&D adventure nor a Hercule Poirot murder mystery. No matter what you call it, it is exceptional, and certainly a fun read. I look forward to the next book in the series, not only for another complex murder mystery but also to learn even more of this unique world.

Highly recommended.
