I like the flavour text as is.

There's certainly a good argument that it's 'giving away too much' and it may end up being unbalanced as hell, but it kinda adds a layer of a murder mystery RPG to the whole thing. It's like we're being led through an adventure by a DM and there are external clues to find, rather than leaving it purely up to the interactions of the participants. And honestly I think there's good reasons to try it like that as well - I've played plenty of Secret Hitler that just descends into circular arguments, baseless accusations and shouting matches because deducing the truth from player's behaviour alone proves to be too difficult.
