Book Review: Termination order by Philip Friedman

Book Review
Termination order

For a history student like me
I really found the book quite fascinating
It filled the gaps in which i couldn't find in my history textbooks about what actually when down during the  nuclear war between USA and Russian and as to why countries like Austria and Italy were involved

Gregory Moore is a CIA agent living in vienna on a mission to get information about the Soviet embassy  to prevent Russia penetrations into the USA
He somehow manages to turn a very important Russian Alexander Rukovoi to work for him by blackmailing him 
Greg somehow managed to make his gathered information seem like Alex and his son are spy(s) 
Now  that  Alex is threatened by what moore might do if he doesnt do as he says  he has agreed to dance to moore 's tune
But moore isn't his only problem Alex reports to Comrade Nevelsky who is somehow a coordinator of the russians
And with nevelsky in his business
Nevelsky commands Alex to feed gregory false information 

On the other side  Gregory Moore  has to report to the American intelligence with his superior Wilson breathing on his neck about the  what not of not reporting  on what he's been working on
Whilst moore tries to convince Wilson that he can't let him in about his russian source for it could blow the whole thing off
Wilson is pretty insistent on being involved or else the whole operation should be shut down

With Gregory and Alex being two sides of same coin knowing that they're not who they pretend to be in vienna will this mission Go on or will it end in blood shed?
