     “A nice imbroglio you've landed me in. Thanks to you ...” “Yes, sir.” “Don't say ‘Yes, sir.’ Thanks to you I have been widely publicized as off my rocker.” “Not widely, sir. Merely to your immediate circle now resident at Brinkley Court.” “You have held me up at the bar of world opinion as a man who has not got all his marbles.” “It was not easy to think of an alternative scheme, sir.”
