I’ve just read The Naval Treaty, and it made me wonder: does ACD’s 221b Baker Street have more than 2 bedrooms?
Because Sherlock says that Percy can stay in the ‘guest room’ (which would obviously be John’s old room, since he’s moved out after his marriage). And yet he knows John will spend the night there too.
John doesn’t even question the bedroom arrangements.
So when John checked up on Percy the next morning and “immediately went to Phelps’s room’, he had slept in Sherlock’s bed. No mention of finding it strange not to sleep in his own old room.
So, WTF? Was there always a third bedroom or had John already spent many nights in not the room upstairs?
