The Night Crawler

The Adventures of Frank Race was an American radio adventure serial syndicated by Bruce Eells Productions. The 30-minute program's first East Coast broadcast was 1949, and the show ran 43 episodes. Because it was syndicated, it aired on different stations on different days. For instance, in New York City, the first episode ran on WINS on April 9, 1949. It "began running in some markets May 1, 1949." The series was broadcast on the West Coast from 1951–52.
