Hello, I'm new to this forum but I just had to register just to get these crazy theories out there! :D

So in the Baskerville episode, we see Watson decipher a morse code that spells out UMQRA. Later it turns out that it was completely insignificant (in a hilarious way I must add!), but the whole thing has just been nagging me after seeing the season 2 finale. Could it really be just meaningless?

The following theories are pretty wild, but give them a chance...

So the morse spells out UMQRA. A meaningless letter combination. But what if the person signalling this code was repeating the code in a cycle, and John Watson just got the letters in a wrong order?

Here are all the possible combinations, if the letters U, M, Q, R, and A are repeated in a cycle:
UMQRA
MQRAU
QRAUM
RAUMQ
AUMQR

Now, I did some research. The only letter combinations that make any sense would be QRAUM and RAUMQ: a quick Wikipedia search lead me to this page on Wikipedia, about a mathematical theory of complete metric space, in German. Whether the mathematical theory itself is significant, I will address later.

Now, "raum" in German means "space", "area", "room". But what about Q? I'm not an expert in the German language (I can say lederhosen and that's pretty much it) but the Source Q theory of the Bible came to mind - "source" or "spring" in German is "quelle". (Also means "well".)

I came up with two wild theories. SPOILERS AHEAD IF YOU HAVEN'T SEEN THE SECOND SEASON OR READ THE ORIGINAL STORIES

So let's say "raum" was meant to mean "room" and Q, standing for "quelle", means "source". Could this be a signal to someone, maybe Sherlock himself, that the "key to open all doors", the absolute source of all knowledge and wealth, can be found in Sherlock's room? The hitmen in the Reichenbach episode we know about were Russian and Albanian, but could there have been a German one? Did Moriarty want to give Sherlock a clue about what is about to come?

The second theory, which kind of melts my hear
