The Brink — John Brunner

Ed Carter, a New York reporter on his way to his home town in Omaha for a short vacation, saw the missile in the last moments in its journey back to earth. A sweller on the brink, like all of us, he had no doubt about what it was; Oh God, he thought, this is it. The blast of the impact flung him some distance, and when he regained consciousness, his first reaction was one of surprised to find himself still alive, and not, it seemed, even badly hurt. Presumably the missile had been directed at the big Air Force base nearby, and should have destroyed everything and everyone within a radius of miles. Could it have failed to explode?

Carter sees the remains of part of the missile in an adjacent field and hobbles over to it. A minute or two later several Air Force officers arrive. They examine the remains, and find the burned-up body of a pilot. In other worlds, the missile was not Russia's first shot in the Third World War, but a failure to launch a man into space. But Carter knows that the Distant Early Warning line will have reported the missile; that the senior Air Force officers, in accordance with plan, will have taken to the air - in the country's interest, their lives must, of course, be preserved if possible; that by now the retaliatory American bombers will have passed the point of no recall; and that the Third World War has begun. Not so, Colonel Ben Goldwater tells him: "I called the bombers back."

Goldwater, the man who had been left in command, has saved the world - for at least a little longer. So he becomes a world hero? Not a bit of it. On the contrary: a nightmare looms ahead both for him and for Ed Carter, and the reader watches it all with growing fury...
