True up to a point.

In conclusion, I think it abundantly clear that what we have been told about what took place [involving Sergei and Yulia Skripal] on 4th March in the beautiful city of Salisbury is not, in fact, true. It is clear that something else happened, and much of what we have seen since then has been theatre and an attempt to cover up what actually took place.^[1]

Mr. Helmer is nothing if not meticulous in nailing down every last detail of whatever he's writing about. Quite an understatement let it be said. The events of the day when the Skripals were eventually found on the bench in town, the honking lack of a chain of custody of their blood samples taken at the hospital, the GRU "assassins" loud partying with whores story, the nerve agent in a perfume bottle disposed of in the trash, the extreme goosiness of Her Majesty's coroners respecting the death of Dawn Sturgess, and, last but not least, the ultra-uber weirdness of the case of the vanishing Skripals in whom the U.S. government apparently has an extreme interest have the internal coherence of a Monty Python script about an accountant wanting to become a lion tamer.

The supposed absolute necessity of tearing off the roof of Sergei's house is a major tell that all is not as it is being represented by the U.K. government, as Mr. Helmer points out. I wonder what it was that Skripal might have poisoned himself and his daughter with. If he did, whatever it was it wasn't a novichok agent as it took its sweet time taking effect. The Skripals clearly enjoyed a leisurely drink at a pub with Sergei's former or present MI6 handler, Pablo Miller, and then a meal before collapsing on the bench just as the chief nurse of the British army happened to be passing by. What a stroke of luck that was!

Ok. Moving right along. Maybe what supposedly poisoned the Skripals had nothing to do with the house but had everything to do with what they ate and/or drank in town. That way one doesn't have to explain the long delay between exposure and result and thus the question of the hour is what was actually in Sergei's house that required removal of the roof and extensive renovation?

I have no insight into that. Back in the years after WWII there was a couple who operated as Soviet spies in Britain. It was later discovered that they had rigged a radio antenna inside their attic but that hardly would be necessary in today's world of the internet of things if Sergei were acting as a triple agent all along. So something besides communication gear.

What was going on in Skripal's house is still a mystery to me but it had nothing to do with a nerve agent. Regardless, it was something hugely important to both the U.K. and U.S. governments. It's almost as though there were a connection between Porton Down and some kind of dangerous pathogen. Did Sergei accidentally reveal something about what was going on at Porton Down? I'm not insinuating there was but with the hindsight of 2021 one can understand why questions about biological research in Britain might be inconvenient. He did have to have a tracheostomy IIRC. Because he had breathing problems? I'll have to double check that.

My two cents.
