Jeff and Debby Spencer
Created by Henry Ingram and Louis Vittes?

The 1940's radio drama, Two On a Clue, spotlighted the cases (supposedly based on actual incidents) of a husband and wife team of private detectives, JEFF AND DEBBY SPENCER. Evidently there was quite a supporting cast, as well, since the info I found listed recurring characters, including The Professor and, even more intriguing, The Midget. Anyone?
