Intriguing indeed, Frank - where will the 'journey to discover the truth' take us?Two entities heavily involved in pre-World War II intrigue were Ethiopia and the Tana Tuva Oblast on the western border of Outer Mongolia. One can't rule them out. Moscow was a cheap place to live, bolstering the case for their involvement. On the other hand, the Terror was still going on, so anyone could be arrested and executed at any time, spy or not. We will probably never know the truth.
