From bestselling true military author Damien Lewis: the incredible story of the radar wars, Britain's most secret battle.

'Nail-biting action all the way - the explosive true story' - Mark 'Billy' Billingham

'One of the most important special forces books written. It traces the daring, ingenuity and sheer courage that is the foundation of the modern service' - Colonel Tim Collins

In the winter of 1941 an alien-seeming object was captured in a death-defying dash by an RAF reconnaissance pilot flying a lone unarmed Spitfire across the French coast. Balanced upon the cliffs near Le Havre was what appeared to be a giant convex dish, directed across the Channel at the war-torn British coastline.
