Trapped in History tells how the British colonised Kenya and how African nationalism arose under Jomo Kenyatta. It describes the terrifying first attacks by the guerrilla freedom fighters known as Mau Mau. Though defeated, the Mau Mau hastened the end of British rule in Kenya. Trapped in History explores the effect the uprising on the author, who grew up as a child in the Kenya colony.

The book is both a history, as well as a memoir, of the end of Empire.
