...and what was the stag night all about?
Why did they take that case when they were pissed?
Did she have an appointment?
We had already established that Sherlock had a 'full inbox' of cases, but wasn't taking them on.
So how did she get through the net?
Plus they had to engineer(badly) that they came back from their stag night early to make it even faintly plausible that they'd interview a client at that time of night.
As my wife said " Let's hope it gets back to being Sherlock next week."
Little hope of that, I should imagine, as the next one is the "Season Finale" so will spend the whole episode building up the next cliff hanger.
I think they've really f**ked this up.
Bloody tragic.
