I started reading this yesterday on the plane and have done little else since. Just about finished now.
This is one of the best books I've picked up this year, and far & away the best account of the Banda era that I have ever read. Jack Mapanje communicates the distrust and paranoia that permeated Malawian society without hitting you over the head with his point. His writing is expertly paced. Even as he describes in agonizing detail the drudgery of prison life, the book remains compelling reading.
I've read prison memoirs before (Fearless Fighter: The Life of Vera Chirwa is also worth a read), but none has ever felt so real to me. This book brought me to tears more than once.
