The Mystery of Otto John.
An Investigation by Rene Cutforth.
Was German intelligence chief Otto John kidnapped from Berlin, or did he defect? Is there perhaps some other explanation? Three times he crossed the frontiers of his world, escaping from Hitler's Germany, vanishing into East Berlin, and escaping dramatically back to the West. Rene Cutforth looks for the clues in the life-story of this gay young man who never dreamed he would be a secret agent or run an intelligence agency.
