The Vanavara Protocol‪.‬

It is 1937. Two archaeologists: one German; the other Russian; are researching three ancient volumes unearthed in the area of the huge 1908 explosion in Central Siberia, 'The Tunguska Event.'

They both have hidden agendas. They have been instructed by their Governments to secretly establish if there could conceivably be any indication of Military significance to the advantage of their respective regimes.

Two of history's most evil men; Reichsführer-SS Henrich Himmler, and Nikolai Yezhov, Head of the Soviet NKVD, are engaged in a sinister game of Double-cross.

Each archaeologist has been instructed to secure any such discovered information, and then, to liquidate their opposite number.

Himmler has code-named his involvement in this deceit as 'The Vanavara Protocol'.
