Jeff Regan, Investigator was one of the three detective shows Jack Webb did before Dragnet (see also Pat Novak For Hire
and Johnny Modero: Pier 23). It debuted on CBS in July 1948. Webb played JEFF REGAN, a rough-and-tough private eye working for the Los Angeles-based
International Detective Bureau, run by Anthony J. Lyon. Regan introduced himself on each show "I get ten a day and expenses...they call me the Lyon's Eye."
