The final four remaining scripts (judging by the airdates listed) were all written by Maurice Joachim. Maurice Joachim was an actor and radio scriptwriter, who wrote episodes of the 1940s WMCA-produced Doc Savage series. It is quite likely he also acted on the Avenger, as he was reputed to be a highly versatile actor -– in the mid-1930s he hosted the "Majestic Master of Mystery" program, and played all the parts himself. Only Joachim and the organist were credited in the script, which had the announcer give the credit “with original music by Dick Ballou”.
