...Perhaps I am prejudiced but the impression which he made on me at the time was that of a conceited, self-opiniated and distinctly stupid man. I admit that he had completely taken Stevens and me in when we met him in Holland but this was not really surprising since he was exceptionally well informed and had been well briefed for the occasion. Besides, the man was a natural conspirator who, as events showed, kept faith with no one. He could therefore play his part with great realism.
