Recently bought a paper copy of this work. It was read in high school.
My perspective on the history of this time has changed since.
Given that what is known to myself I have some suspicion about veracity and or completeness.
In that the Intell houses of the 'big three' were involved to some extent suspicion is only natural.
Dangle doesn't apply, too simplistic to me. Dangle was Oswald by Angleton.
I seek peer review.
My opinion leans towards the Gentry/Facilitators running an op to exercise some control over who knew what in the intentional Missile Crisis upcoming.
Implied by timing, did the "free" two Intell Spook Houses surrender their spy-in-place to the others?
I find odd some descriptions of Soviet citizens' living conditions, oppression and such. Knowing that some US operatives were flown into the Soviet Union on S.T.O.L. aircraft,
Would one knowing tradecraft as Mr. Penkovskiy did, keep a journal?
I figure all that is for debrief from memory.
I conclude that this work is much disinformation and as much truth as allowed in the super state then and now to lend credibility.
I do not doubt the veracity of Mr. Penkovskiy, I doubt the veracity of many assets involved in bringing the journal to the public.
The timing and means of publication I fond odd.
