How about a few episodes of A Life in Your Hands, an old radio show "created by Erle Stanley Gardner"?
The show ran during the summers of 1949 to 1952 and featured the character Jonathan Kegg as an amicus curiae interested in justice being served. Kegg was played at various times by Ned Lefevre, Lee Bowman, and Carlton Kendall. I don't know much about the show and I really don't know how much Erle Stanley Gardner had to do with it. Maybe as much as Ian Fleming had to do with The Man from U.N.C.L.E.? Or, maybe not.
Anyway, the link will take you to thirteen episodes. Have fun.
