This interview-style podcast investigates the death of King Boris III of Bulgaria, exploring whether it was a natural death or assassination. The episode begins with a description of the King's state funeral and then delves into interviews with family members who recount their memories of the event, including the chilling experience of kissing the King's cold forehead. The investigation explores various theories, including poisoning by Nazi doctors, focusing on evidence from Goebbels' diaries suggesting the use of Asiatic snake venom. A herpetologist is interviewed to discuss the feasibility of using snake venom as a murder weapon, ultimately concluding that injection would be the most likely method. The episode concludes by questioning whether the British, rather than the Nazis, had the motive and means to assassinate the King, leaving the question of who was responsible unanswered.
