The Pigeon Tunnel', John le Carré's memoir and his first work of non-fiction, is a thrilling journey into the worlds of his 'secret sharers' - the men and women, who inspired some of his most enthralling novels - and a testament to the author's extraordinary engagement with the last half-century. The reader is swept along not just by the chilling winds of the Cold War or by the author's frightening journeys into places of terrible violence but, most importantly, by the author's inimitable voice. In this astonishing work we see our world, both public and private, through the eyes of one of this country's greatest writers.
