Once upon a time, in a small town just outside of Chicago, lived a very shy, young professor. The last living descendant of one of history's most dashing lovers, and whose name therefore was Casanova. Casanova Brown. Since he was a quiet, conscientious, very good young man, people had long since forgotten the Casanova, and simply called him Cas, or Professor. The story begins with Cas nervously waiting to speak with the father of his chosen lady, to officially request her hand in marriage.
