"There are some indications that the police officer who was injured had been to the house, whereas there was a doctor who looked after the patients in the open, who hasn't been affected at all. So there maybe some clues floating around in here.'"As I pointed out in that piece, the phrase "some indications" was somewhat disingenuous, as The Metropolitan Police would have known by that time exactly where Mr Bailey had been. And in any case, there was no particular reason for Lord Blair to reveal this information.
The point I went on to make is that if it was known that he had been poisoned, which it was; if it was known that he'd been to the house, which it was; and if it was known that the poisoning didn't happen at The Maltings, which it was (at least according to investigators who ruled it out with surprising swiftness), then it MUST have been known that he was poisoned AT THE HOUSE. But if this was the case, why exactly was the house not locked down, with forensic scientists all over the house taking swabs? Why did it take nearly two weeks for that to happen?
Comment: And where exactly is Det. Sgt. Bailey? Hanging out with Sergei Skripal perhaps? Isn't it a bit odd that he hasn't been seen or heard from since he was released from the hospital?
