Obi Okonkwo's slide into bribe-taking
The Umuofia Progressive Union, a hometown association of villagers working in Lagos, pools money to send Obi Okonkwo to study in England. He returns to a senior civil-service post on the Scholarship Board, publicly condemns bribery, and refuses early offers. Squeezed by loan repayments, car costs, family school fees, his mother's death and his thwarted engagement to Clara, he begins taking bribes and is caught in a police trap; the novel opens at his trial, with everyone asking why an educated idealist did it.
