What a story this guy has. Being a spy for multiple parties, finishing up as the claimant of being the Dalai Lamas reincarnation then dying under suspicious circumstances after writing Hitler to stop the holocaust.
The wiki page speaks for itself.

Yeah, if the Japanese ever got to Tibet, he was the officially supported candicate.
