Unsuspecting Guard

This was a really good mission; it definitely felt like a busy, inhabited castle/mansion with the readables, detailed decoration, and so many occupants. I thought that all the 'shift change' notices were just for atmosphere, so had a real shock when I came back to the barracks (which I thought I'd cleared out already) to find 3 different guards hanging around. I'm usually quite dependent on the blackjack, but next time I play this I'll KO as few people as possible to get the most of the shift change mechanic.
