There’s a Sherlock Holmes line that gets repeated in nearly every adaptation verbatim. It’s a note from Sherlock to Watson:
Come at once if convenient. If inconvenient, come all the same.
They always find comical ways to make the letter are at the most inconvenient times. And Watson does always come right away, out of loyalty and curiosity (though often tempered with a fair amount of annoyance ;)).
But I’ve been reading the original Sherlock Holmes stories for the first time because of a roundabout chain of events. Seeing Dr. Strange on a flight led me to rekindle my curiosity in the British Sherlock series starring Benedict Cumberbatch.
