Black as He's Painted (1974)

TRIBAL TREACHERY

The president of an African republic is planning a good-will mission to England, and someone seems intent on including murder in his itinerary!

Inspector Alleyn, normally exempt from duty on security protection, finds himself with a ticklish predicament. On one hand, a flamboyant African politician with a Gandhiesque view of the world. On the other, a colorful killer whose feathered spear is aimed with deadly accuracy at World War III!
