Police procedural introducing Darko Dawson, a detective inspector from Accra who is sent to the village of Ketanu to investigate a murder. The story weaves Ghanan customs, the disappearance of Dawson's mother when he was a child and the story of a young woman who is studying to be a doctor and volunteering as an AIDS worker. Wife of the Gods references the young women who are sent to live with fetish priests. Gladys Mensa, the AIDS worker, interacts with Togbe Adzima, the fetish priest in Ketanu, encouraging him to change his ways. The wives of the fetish priest was a bit of a red herring for me -

Spoiler

as I was convinced the murderer of Gladys Mensa came from that household.

Dawson has to navigate between a village he visited as a boy, his current life in Accra, the rough techniques of the local police captain, the tribal customs in Ketanu, his mother-in-law attempting an herbal remedy for Darko's son as well as Darko's personal darkness.
He is a man with flaws - but he got the job done.
