Winter in Madrid - C. J. Sansom

940: The Spanish Civil War is over, and Madrid lies ruined, its people starving, while the Germans continue their relentless march through Europe. Britain now stands alone while General Franco considers whether to abandon neutrality and enter the war. Into this uncertain world comes Harry Brett: a traumatised veteran of Dunkirk turned reluctant spy for the British Secret Service. Sent to gain the confidence of old schoolfriend Sandy Forsyth, now a shady Madrid businessman, Harry finds himself involved in a dangerous game - and surrounded by memories. Meanwhile Sandy's girlfriend, ex-Red Cross nurse Barbara Clare, is engaged on a secret mission of her own - to find her former lover Bernie Piper, a passionate Communist in the International Brigades, who vanished on the bloody battlefields of the Jarama. In a vivid and haunting depiction of wartime Spain, Winter in Madrid is an intimate and compelling tale which offers a remarkable sense of history unfolding, and the profound impact of impossible choices. 'Sansom adroitly draws the disparate strands of his ambitious saga together. His non-pareil evocations of time and place anchor his characters with satisfying precision' Independent.
