Rudolf Hess was the most closely guarded prisoner in the world. Forty-five years after his capture in Scotland on a supposed peace mission he was still in Spandau Prison. Why was it necessary to keep him there so long? He was a Nazi -- but one with a damaging tale to tell. If anyone can reach him it is Berlin correspondent Red Goodbody, known for his foolhardiness, but also for his daring and panache. The fear is that the stability of Western Europe may be undermined by what Hess can reveal; and so both the KGB and MI5 move into action to protect the extraordinary secret of Spandau.
