Another fascinating story set in the same setting (but after the events) of the author's story, "A Dead Djinn in Cairo", this one has two agents of the Egyptian Ministry of Alchemy, Enchantments and Supernatural Entities looking into the possible haunting of an aerial tram car. But what starts off as a possible 'simple' possession by a djinn evolves into something much darker, as further investigations start to reveal the true nature of the spirit occupying the tram car.

Woven into the tale is a background of female emancipation with a vote to be taken to give women the vote, which would give the agents more food for thought in the involvement of women in their work in the future. Quite a number of interesting secondary women characters are in the story, providing some humour and alternative viewpoints.

In the end, the agents solve the case, but not without some dramatic crisis points in the story.
