Spies in the Sky fills in a huge gap in Second World War historiography in both an exciting and intellectually stimulating way. No-one will be able to write a history of the conflict again without giving Medmenham its central role in Allied Intelligence-gathering. -- Andrew Roberts, Author Of The Storm Of War A fascinating read and a significant contribution to the history of World War Two. The code-breakers of Bletchley have become internationally renowned. Now Taylor Downing tells the unsung story of the photo-analysts of Medmenham and the heroic pilots in the skyplanes, putting them back where they belong - at the heart of Britain's secret war. Professor David Reynolds, author of In Command of History Taylor Downing's brilliant research has created a ripping yarn. Kevin Wilson, Sunday Express Spies in the Sky combines the breathless courage of pilots ... with the mild eccentricity of RAF Medmenham. There's a diverting cast of characters, from Winston Churchill's daughter Sarah to the young matinee idol-to-be Dirk Bogarde, and there's a beguiling account of the way in which the maverick pilot Sidney Cotton ... fought the brass-hats in Whitehall. Sinclair McKay, Daily Telegraph Spies in the Sky gives a new perspective to some of the most famous moments of the conflict. Robert McCrum, Observer

Taylor Downing was educated at Cambridge and went on to become Managing Director and Head of History at Flashback Television.
