Alan Johnston explains how "Homage to Catalonia" by George Orwell inspired him to become a journalist - and taught him some dark truths about politics. At one point Johnston looked to be destined for a career in town planning. But that all changed when he came across Orwell's book on the Spanish Civil War. "Homage to Catalonia" set Johnston off down a path that would take him to wars and upheaval in the Caucasus, Central Asia, and Afghanistan under the Taleban. He was on a journey that would eventually lead to his being kidnapped in Gaza.
