MQuarrie, the City Editor, looked up as I entered his office. "Bond," he asked, "do you know Jim Carpenter?" "I know him slightly," I replied cautiously. "I have met him several times and I interviewed him some years ago when he improved the Hadley rocket motor. I can't claim a very extensive acquaintance with him." "I thought you knew him well.
