Ellery Queen's Mystery Magazine (EQMM) and Alfred Hitchock's Mystery Magazine and EQMM was the first market I started pitching when I began writing mystery fiction. I badly wanted to be selected for their "first mystery" story but I never made the cut.
Of the two magazines, I preferred EQMM and I eventually went on to read the Ellery Queen mystery series. Ellery Queen started appearing in movies, and eventually in a television series starring Jim Hutton, which I remember enjoying. Full episodes of the series are posted at imdb. In a way, the Ellery Queen series was a precursor of Castle. Queen was a mystery writer. His father (played by David Wayne) was a police inspector and he helped him solve mysteries. I'm surprised no one has rebooted the series yet. Ellery Queen has been around for a long time since being created by two writers who were cousins. It's one of the most successful mystery franchises/brands ever, spannign 42 years.
