Radio crime fighters

"This work covers over 300 syndicated radio mystery and adventure serials that aired through 1962. To be included in the book, a series must have included one or more characters who regularly appeared in occupations or avocations that fought against espionage, theft, murder, and other criminal activities. Each entry includes the name of the series, air dates (stations and times are noted), the sponsor, number of known extant episodes, cast information (such as the directors, writers, composers, announcers, lead actors and supporting actors), and a brief synopsis."--Jacket.
