I listened to an OTR Inner Sanctum Episode called "Two Sisters", from the 1940's, that was also produced by the late Himan Brown. I think most scripts, including this one, for CBS Radio Mystery Theater,  were much better than those written and produced than those for Inner Sanctum radio show. Listen to both "Two Sisters" episodes- what do you think? Interestingly, besides this one, I don't think Himan Brown used very many stories from Inner Sanctum on Mystery Theater. Also, regarding OTR, I do think that the episodes written by Lucille Fletcher for Suspense radio show were superior to most others on any show.
