It is 1940. The Spanish Civil War is over, and Madrid lies ruined, its people starving, while the Germans continue their relentless march through Europe. And as Britain stands alone, General Franco considers whether to abandon neutrality and enter into the war. Into this uncertain world comes Harry Brett, ex-public schoolboy, traumatised veteran of Dunkirk, and, now, reluctant spy for the British Secret Service. Sent to gain the confidence of Sandy Forsyth, an old school friend turned shady Madrid businessman, he finds himself involved in a dangerous game--and surrounded by memories.
