Ace Up My Sleeve: It's not a playing card though. Talk to Paola again and she'll give you the hookup with a cool weapon. Problem is, it doesn't work yet. You need to bring it to Leonardo da Vinci, who's just across town. Make your way to him and knock on his door for a lengthy cut scene.
After giving you the hidden blade, Leonardo is interrupted by a guard at the door. While Leonardo is taking his beating, equip the blade and walk up behind the guard. Press the attack button for an instant assassination. At Leonardo's request, pick up the body and carry it into his workshop. Drop the body in the wisp of white light to complete the mission. For more info, watch the whole gameplay.
