Act 4: Interrogation the French

If this is done with Pierre Paré's blessing, it should go pretty smoothly. If not, they may get the Signoria on their case.

Scene 1: Zeroing In On Ambroise Amyot

Setting: Probably at the Loggia della Signoria , in the Piazza della Signoria, where the French delegation is staying.

Activities:

Interrogation
Everyone has an alibi
Detect Lies
Amboise Amyot is lying.
Influence
To keep the Signoria out of it

Success: They know only Amboise Amyot does not have an alibi. Most likely the MHs will shadow him until he goes werewolf, at which point they fight to the death.

Failure: They gain not useful information and may have involved the Signoria, Act 5.
