The Instrument by Victor Thorpe

A terrible crime wave has hit Nigeria. People are being terrorised and the Government is puzzled by the large number of brutal murders and the spate of gold thefts. Paul and Aimie Okoro find their peace and quiet, so well earned after their adventures in The Worshippers, is shattered when they are called to help their country in its hour of need. Once again they battle against the sinister forces of darkness, armed with their own courage and helped by strange forces that even they find difficult to understand.
