I don't see how you can say that something that is historical fact is the same as a 'thriller' for example, (which is a work of fiction.) and that ' spoilers' apply.
If for example, you watched a programme on Henry V111 and his wives, would you accuse someone of 'spoilers' if they mentioned (before the series had ended) that he had 5 other wives?
Once I knew this series was on TV I was genuinely interested in reading about it. This is the Radio Times www.radiotimes.com/news/tv/2018-12-05/what-is-the-real-life-story-behind-ruth-wilsons-new-bbc-drama-mrs-wilson/
I don't see whether he had 2 wives or 22 makes any difference. Each woman- whether 1 or 21 - was duped by him.
IMO it throws up really interesting discussions around how and why an intelligent man would do this, were the marriages part of the 'deal' with the security services, to keep him off the radar, or create some cover, why did he go to the lengths he did to deceive people?
It's about human nature, decisions made perhaps to protect our security and a whole lot more.
If you care to read the RT piece, you'll see that even now- 70 years on- the security services still won't reveal some facts about his work or his life (hence no answers for us yet over why he did what he did.)
I can't see in all honesty why you are miffed or bothered about yet another wife in the background. It's been pretty clear all along anyway that there were plenty more skeletons in the cupboard.
It's not a 'thriller' - it's a real life, historical account.
