"Many thanks for sending me your book Banking on Death which I have read with pleasure. I observe from the cover that you are two ladies, but I cannot believe that both of you have read Principia Mathematica. Hitherto I have only known of six people who have read it, three Poles, who were liquidated by Hitler, and three Texans, who were absorbed by osmosis into the general population. I wonder whether you found the book a help in writing fiction."
