The Blackmailers by Joseph Mangut

Danjuma Dauda is a thoroughly dissatisfied man. In spite of his degree, he is stuck in a poorly paid job as a cashier with no prospect of promotion. He no longer appreciates his wife and is ashamed of his home. He is the perfect prey for a ruthless gang of Army deserters who terrorize Rock Town. They want money and Danjuma wants most anything that will get him out of his dull rut. It is not long, however, before he finds out that things are not as simple as he believed. Crime does not always pay.
