The Irresistible Concept is fiction and on the genre of mystery that I term "traditional mild horror." Attalia, a client of Osigbo (a traditionalist and herbalist) gains a supposedly higher spiritual power than Osigbo: a spiritual power that cannot be resisted. Attalia extends hatred and the same fight to his nephew, Sylvester. Who will then win this spiritual fight: Osigbo, Attalia or Sylvester in this spiritual fight?
