For 650 days Sean Turnell was held in Myanmar’s terrifying Insein Prison on the trumped-up charge of being a spy. In An Unlikely Prisoner he recounts how an impossibly cheerful professor of economics, whose idea of an uncomfortable confrontation was having to tell a student that their essay was ‘not really that good’, ended up in one of the most notorious prisons in South-East Asia. And how he not only survived his lengthy incarceration, but left with his sense of humour intact, his spirit unbroken and love in his heart.
