He was the golden age of radio's last detective, a character played by more actors in a dozen years than James Bond was in 50. It's been more than 50 years since his last expense report, but one case remains - The Last Man Standing Matter.
Tweaking continues, mostly minor details like on-screen text, though, I'm considering rearranging the order of segments a bit. The challenge remains having a wealth of great material from interviewees such as the late Ed Walker that's interesting in its own right but doesn't necessarily fit the overall story. There's probably a separate documentary about radio drama in general to be made.
