[hider=Spoiler]It was me, in another thread, mentioning an episode where it came up. :hehe

Also, funny thing, I actually guessed that Missy was the Master waaay back when Into the Dalek came out (mainly because of the whole Missy/Mistress/Master name thing), but then I abandoned the theory like halfway through the season, especially when The Caretaker implied that she was God and I started thinking, "Yeah, this scheme is way too elaborate to be the Master", sooooo by this point I was no longer expecting it. o.o 

What's amazing, though, is the way that Missy kept dropping hints that she was the Master as the episode went on, just waiting for the Doctor to figure it out (and thus leading me to realize that the theory from early on actually was correct, much to my surprise)... but then by the end she's like, "Come on, Doctor - Missy, Mistress, Master..." just spelling the whole thing out for him with something that a bunch of fans had figured out a long time ago.
