Love the alternate universe revealed here, with Cairo and Egypt becoming a major world power, likely due to the discovery of Djinn leading to a boom in innovation. Granted, this is a short story, so much of the how Cairo got to where it is, is not discussed. That said, the murder of the Djinn of course leads to a major conspiracy that our intrepid police detective must unravel. The book is filled with strong female protagonists and characters and a world that has had the breath of life and magic breathed into it. Definitely recommend if you like speculative fiction of this type.
