The Hound of the Baskervilles tonight & - as I said to two of my students (self-confessed Cumberbitches) - I begin each new episode with trepidation: will it be as good? When will there be that sickening feeling of realisation that the magic has gone ... the writing thins ... ?

Pleased to report: not yet!

(Utterly absurd, of course, that Mycroft's card could get them into the base so easily ... or maybe it is all part of a grander scheme? My money is on some kind of mind control - rather than an actual genetic monstrosity - & this would explain why Sherlock is so disturbed. Don't mess with the mind palace ... ).

Paused at 45 mins. The rest tomorrow ...
