I just finished listening to "The Seventh Man" - which turns out to be the third in a 4-part series. I guess I'll go listen to the first two now.
The 4th in the Dan Barry series, "Dan Barry's Daughter", is available. It's on Hathi Trust, here: https://catalog.hathitrust.org/Record/100824409
I haven't found it on Archive. I see it on Google Books, but I only have a limited view: https://books.google.com/books?id=4iRMAQAAMAAJ
Richard Kilmer read the first two. He's gone to the Great Library in the sky. Robert Keiper read the third, but he hasn't logged in for 4 years.
Dan Barry's Daughter by Max Brand (Western)
I was about to suggest this.
