It was revelations of "grueling poverty" in numerous "spoiler" that startled me. There was very little evidence of this poverty -- even if it was made clear that there was a lack of money ... but really I don't remember, we have no food until it appeared in the final segment during prison visitation. Allison's mother said something about not helping out (though I wonder who is paying for son's college and other expenses).
The idea that Alec was set up by a rival faction apparently has some credibility and might explain the continuing classification of various records.

""We know for certain that something went wrong when he was managing the trading of ship’s stores for a surrendered German passenger liner, the SS Prinzessin, and led to his arrest and prosecution in Vancouver in September 1919.
He was arrested the day after his father died thousands of miles on the other side of the world while on leave from France at Minster, Isle of Sheppey.
He was subsequently sentenced to six months hard labour in one of North America’s most notorious jails, the Oakalla Prison Farm, a veritable and notorious model for the gaol culture represented in the film ‘The Shawshank Redemption.’""
I was most surprised by this mention of the 1919 arrest and conviction after WWI, but before he appears to have engaged in intelligence related daring-do .... but would they have hired him if they knew .... or did they know and hired him anyway and that's their dirty little secret???
also from same source -- before --
""We know for certain he taught English Literature as a professor at Islamia College, University of Punjab in Lahore between 1925 and 1931, eventually taking over as Principal in 1928.''
