One very noirish mystery that has always fascinated me is the death of TV's Superman George Reeves. It was 52 years ago yesterday that he was shot to death in what was determined to be suicide. The controversy surrounding the facts of his last night alive and subsequent death, in the early morning hours of June 16, 1959, started immediately and has never subsided.
