Okay, I've had a quick re-read over the posts, and since we don't have any maps done up for the layout of the manse we'll just go with plot-visibility. If anyone thinks their character would reasonably be in position to see / hear anything strange, they can be, and can act accordingly. For NPCs, again, if you think they're in position to see / hear things, go for it.<br/><br/>If you want to add a little randomness, give them a roll to see if they noticed. 4 dice is probably okay for a guards dice pool for something like this.
