In this tale of political greed and hypocrisy, first published in 1977 and now a Penguin Classic, the Kenyan novelist follows the fate of four suspects after three prominent local businessmen have been murdered in a small village in the highlands of Northern Kenya. This is the fourth novel by Ngugi and his first set since independence. It's both a suspenseful tale and a critique of post-colonial Africa.  (EAF135, $15.00)
