Radio Dramas from 30's and 40's

Recently discovered (very recently, like two days ago) US radio dramas from the 30’s and 40’s with big Hollywood stars of the time and became a small fan. I knew they existed because some are used as extras in WB’s R1 DVDs but I had never bothered… until I listened to Myrna Loy in “Library Book” (from a radio show called “Suspense”)… and I loved it! It is a hilarious comedy mystery about a prim and proper librarian who discovers that a page is missing from a copy of “Gone with the wind” and that it was used to write a ransom note.
