Sonokrom, a village in the Ghanaian hinterland, has not changed for hundreds of years. Here, the men and women speak the language of the forest, drink aphrodisiacs with their palm wine and walk alongside the spirits of their ancestors. The discovery of sinister remains - possibly human, definitely 'evil' - and the disappearance of a local man brings the intrusion of the city in the form of Kayo, a young forensic pathologist convinced that scientific logic can shatter even the most inexplicable of mysteries.

As old and new worlds clash and clasp, and Kayo and his sidekick, Constable Garba, delve deeper into the case, they discover a truth that leaves scientific explanations far behind.
