A Drop of Corruption
What it's about
In the canton of Yarrowdale, at the edge of the Empire, a Treasury officer vanishes from a room locked from the inside, in a building whose every entrance is guarded. The Empire sends its most brilliant and eccentric investigator, Ana Dolabra, and her bemused assistant, Dinios Kol, whose altered memory lets him record everything he sees. What they uncover goes far beyond one missing man.
Why it's worth reading
It was a Hugo Award finalist and a Goodreads Choice finalist. It's a clever locked-room mystery in a strange, vividly imagined world, with one of fantasy's best detective partnerships.
