1950: Jeff gets caught up in a case of missing memories. Could a mystery woman carrying a pistol be a murderer?

Starring Paul Dubov as Jeff Regan and Frank Nelson as Anthony Lyon.

Jeff Regan is a fully registered official private investigator working for the Los Angeles-based International Detective Bureau. Unlike some of his radio contemporaries, Jeff gets the job done through diligence and tenacity - rather than gun-toting fisticuffs.

The series debuted on CBS in the US 1948 starring Jack 'Dragnet' Webb. After he left the role on radio, Jeff was played by Frank Graham and finally Paul Dubov (1918-1979) who appeared in many Hollywood films as a support actor, rather than playing the leading man.

Jeff Regan, Investigator came off-air in 1950.
