“Riemeck had no car himself, he could not have followed de Jong from his house in West Berlin. There was only one way he could have known—through the agency of our own Security police, who reported de Jong's presence as a matter of routine as soon as the car passed the Inter Sector checkpoint. That knowledge was available to Mundt, and Mundt made it available to Riemeck. That is the case against Hans-Dieter Mundt—I tell you, Riemeck was his creature, the link between Mundt and his imperialist masters!”
Fiedler paused, then added quietly:
“Mundt-Riemeck-Leamas: that was the chain of command, and it is axiomatic of intelligence technique the whole world over that each link of the chain be kept, as far as possible, in ignorance of the others. Thus it is right that Leamas should maintain he knows nothing to the detriment of Mundt: that is no more than the proof of good security by his masters in London.”
