Your primary target for this mission is Sivert. Located within the iconic Notre Dame Cathedral, this assassination presents two distinct tactical opportunities: stealing the keys from the nearby pickpockets to unlock the upper clerestory windows for a "Secret Entrance," or using the "Duchesneau" opportunity to trigger a unique kill. By killing the accomplice Duchesneau in the graveyard and taking his place, you can enter the central confessional to assassinate Sivert while he believes he is speaking to his subordinate. use the cathedral's intricate verticality and crowded pews to maintain stealth, and ensure you have identified your leap-of-faith exit points before striking.
