"Later, a long time later, I learned that the Dakota Maru had passed safely through the submarines with 50 American flyers aboard. Charlie had sent this message in time. He had performed his last service for the OSS. The last but one, I mean—the very last had been to die for it."

Unique Aspects of the Episode
- Graham highlights the unusual perspective of the narrative—told from a local’s point of view, rather than the OSS agent’s—which “is very earthy for the era” and “really fleshed out this character.”
- Praises Brenda Rayburn’s (Bryna Raven) performance as Tanya:
"Brenda Rayburn is just great in this. She's a fantastic performer and also a really good narrator and brings the story to life... she is so unique for a viewpoint character. I don't believe I have ever heard a character like her as this again."
- Discusses Ian Martin’s range as an actor for playing both the undercover Charlie and his real identity: “I was a bit stunned when I heard the real voice after having heard the Undercover Charlie voice... I would never have guessed it was the same actor.”
Listener Feedback
