This was adorable. It’s a standard setup: a tough, experienced detective has a murder mystery to solve, except in this case the tough detective is the youngest woman working at the Ministry of Alchemy in a magical version of historic Cairo; the murder is of an entire secretive brotherhood; oh, and the repercussions of her investigation threaten to tear down the thin barrier protecting the physical world from the magical realm. Great cast of characters, great progression of plot, really enjoyable read.
