"Several years ago, Taylor Caldwell invited the Duchess of Windsor for a luncheon with fifteen others. The Duchess's secretary phoned Miss Caldwell to ask what transportation was being used, and she replied, "her husband would drive over to pick up the Duchess". The secretary replied, "I'm sorry, Miss Caldwell, your husband is Jewish and the Duchess does not mix socially with Jews". Taylor Caldwell then exploded, "Tell the Duchess, I am Dutch Protestant and I don't mix socially with prostitutes.""
