Flight Lieutenant Silk, a twice-decorated Lancaster pilot in WW II, rejoins the R.A.F. and qualifies to fly the Vulcan bomber. Piloting a Vulcan is an unforgettable experience: no other aircraft comes close to matching its all-round performance. And as bombers go, it's drop-dead gorgeous. But there's a catch. The Vulcan has only one role: to make a second strike.To act in retaliation for a Russian nuclear attack. Silk knows that knows that if he ever flies his Vulcan in anger, he'll be flying from a smoking wasteland, a Britain obliterated.But in the mad world of Mutually Assured Destruction, the Vulcan is the last - the only - deterrent. Derek Robinson returns with another rip-roaring, gung-ho R.A.F. adventure, one that exposes and confronts the brinkmanship and sabre-rattling of the Cold War Era.
