"The landmark series was Dimension X, which was broadcast by NBC....It was the first radio series to treat science fiction in an adult way." (Mike Ashley, Transformations: The History of the Science-Fiction Magazine 1950 to 1970)

Short Radio Drama Worth the $1 or So

Any additional comments?

Entertaining short story, short radio program, with some Brownian motion: some twists and turns as Martians and Men mentally fence. The knock on the door changes meaning, from beginning of story to end.
