PETALS OF BLOOD (Ngugi wa Thiong'o)

“After a terrible murder in the village of Ilmorog, four suspects are placed in detention: the headmaster; the storekeeper; the assistant teacher and the barmaid. Their lives are inextricably linked with the lives of the murder victims, the fortunes of Ilmorog and with the fate of Kenya itself.”
“Published to great controversy (…) it is as much a whodunnit as a political novel and satire.” (Nielsen BookData Online)
