( . . . Martin Freeman is the one who reminds Sherlock that they have to pay the electric bill, that the refrigerator is not the place to store severed heads and that his ‘useless’ blogging of Sherlock’s exploits is what brings in the customers. )

And yet another thought pops into my head: one common thread through all of the contemporary (and written, although to a lesser extent) incarnations of Sherlock, and a key part of his character is that he gets more than a little crazy when he gets bored.

Something else you could readily transport to the third imperium version...
