Stealth Assassination (Garnier de Naplouse)

Stealth Assassination (Garnier de Naplouse) was a virtual representation of one of Altaïr Ibn-La'Ahad's genetic memories, relived by Desmond Miles in 2012 through the Animus.

Description
Altaïr met another Informant in the city, who requested the Assassin's help in exchange for information on Garnier.

Dialogue
Altaïr approached the Informant hiding near the city wall. Altaïr agreed to help, and eliminated the Hospitalier shortly after, before returning to the Informant.
 * Informant: Altaïr! He's after me! He saw me! He will kill me! And my wife and children! What a mess! Have you come to end my misery? No? Al Mualim has more compassion than I thought. Could you help me then? A Knight of the Hospitalier's after me. If you could eliminate him, you would do a fellow a real honor. I've been here in Acre since the Crusaders were laying siege. I can give you important information in return.
 * Informant: It is done? He's dead? Oh, I am extremely grateful. So, here is what I know about Garnier de Naplouse, Grandmaster of the Hospitalier. Garnier lets his patients roam the halls of his fortress. No one, save scholars, may enter his personal workspace, and the rooftops are guarded by archers. I'm sure this information will help deliver Garnier, to the gates of hell.

Outcome
Altaïr assassinated the target specified by the Informant, and learned that Garnier let his patients roam the fortress freely. He also learned that only the scholars had access to Garnier's personal workspace.
