Garson Krebs, P.I. is on the trail of a war criminal on behalf of the British MI5 in The Man With a Past. Written by Larry Weiner and Produced by Angelo Panetta for The Radio Repertory Company of America.
And Dick Powell stars as Richard Diamond, P.I. in a 1951 case called A Man With a Scar. The series began on NBC in 1949 and moved to ABC radio in 1951. Dick Powell usually ended each of the episodes singing a song to his girlfriend, but this is one of the later shows and he has no song in this one. Richard Diamond has an easy manner and a quick wit in the radio series, unlike the tougher version of Diamond in the TV series, as played by David Janssen.
