211. The Mysterious Death of Double Agent Ralph Sigler

from SPYCRAFT 101 · host Justin Black

 Today's episode is another solo episode where Justin shares his own research with you. This time he's talking about Ralph Sigler, a US Army warrant officer, and one of the best double agents in Army history who died under mysterious circumstances in a Maryland hotel room in 1976. We briefly discussed Sigler's death way back in episode 76 in December, 2022, but Justin decided this case was worth a much more in-depth exploration.
