First of three films based on the popular radio series, 'I Love a Mystery'. The next two were The Devil's Mask and The Unknown.
Mr. Kerrigan's brief outline should refer to "Jack - not Joe - and Doc" for Jack Packard & Doc Long played by Jim Bannon and Barton Yarborough. These characters were first introduced on an earlier Carleton E. Morse radio series as San Francisco private eyes in "Adventures by Morse". When he returned to the air after WWII, writer-producer Morse added their posh British thrill-seeking buddy, Reggie York (Tony Randall). Most of the female roles, whether good girl or bad, were performed by Mercedes McCambridge who often superbly juggled 2 or 3 different character voices on the 15-min weekday serial and later half-hr weekly program.
