Jeff Regan, Investigator came to CBS Radio on July 10, 1948, with Jeff Regan as a tough private eye working for a detective agency run by Anthony J. Lyon. Regan introduced himself on each show with: "I get 10 a day and expenses. They call me the Lyon's Eye."

Lyon, portrayed by Wilms Herbert, ran the International Detective Bureau, a small private investigations firm in downtown Los Angeles, with often oversized ambitions. Regan handled rough assignments from Lyon, with whom he was not always on good terms. Actor Jack Webb played Regan as tough and tenacious, with a dry sense of humor. The series ended when Webb left the show in December 1948, but was resurrected in October 1949 with a new cast. Frank Graham starred as Jeff Regan, and Frank Nelson portrayed his boss, Anthony J. Lyon. This version lasted until August of 1950.

Enjoy 12 episodes from this terrific hard-boiled detective series, with the first four episodes starring Jack Webb, and the remaining eight starring Frank Graham.
