Chinua Achebe 
Anthills of the Savannah 

'[The writer] in whose company the prison walls fell down’ – Nelson Mandela. After a long silence Achebe published in 1987 what many see as his greatest work – an acrid, frightening look at oil-boom Nigeria, a world of robberies, road blocks and intimidation in which those who are meant to be protecting a country’s citizens are in reality supervising the looting.
