David went and waited outside the apartment Anne lived in. He waited until evening, when Anne returned to her apartment. Once David spotted her, he went up to her and knocked her unconscious. David carried Anne and brought her to the roof of her apartment building.
On the roof, David dragged Anne's body to the edge and released his Hidden Blade. "Sorry, fellow mercenary. But you are a traitor, and traitors have to die." David searched Anne and found a dagger and a note. Seeing the dagger, David kept his Hidden Blade and instead used the dagger to slit Anne's wrists. After making sure Anne was not breathing anymore, David placed the dagger in her hand. David looked around the building from the roof and saw five men walking towards the building. Examining them closely, David saw that they were armed.
David climbed down the building and read the note while walking. After he finished reading the note, David tucked it into his robes. The note was from Anne's Templar contact, who had signed off as 'Zeus'. The note stated the location and timing for Anne to meet the contact.
Fifteen minutes later, David sat down at the bar and ordered himself a glass of beer. He sipped from the beer as he scanned the bar for anyone who could be the Templar contact. David saw a bearded man a few tables away, who was not drinking anything and seemed to be waiting for someone. Examining him closely, David saw that the man was wearing a Templar ring.
At the same time, the bearded man spotted a clean-shaven man looking at him. The man looked like a fairly wealthy businessman to him, but his clothing seemed like an Assassin's. The bearded man caught David's eyes looking at his hands. The bearded man determined that the other man was an Assassin and that he was there to kill him, a Templar. And he was right.
The bearded Templar reached for his pistol while David pulled out his pistol. Both stood up and aimed the pistols at one another. "Damn Assassin, you're here to kill me, are ya? Ya probably killed Anne too, you bastard!" the Templar snarled.
David retorted, "Of course I did! We Assassins are stronger than the Templars in America. We knew about O'Neemas! Luckily, she was killed before she became too much of a pain!"
The bearded Templar opened his mouth to say something, but David had fired a round into the Templar's throat. The force of the round hitting the bearded Templar's throat caused him to tip the chair backwards. The bearded Templar ended up on the floor, his blood getting on the chair.
David stood up and walked over to the Templar. He knelt and searched the dying Templar and took his Templar ring and money. David got up, kept the money, ring and his pistol and walked out of the bar.
David returned to the mercenary hideout and saw that Joseph Caysee and a group of mercenaries were at the ground floor. All were sitting and discussing about things. David asked, "Why are you all here?"
Joseph looked up at David and informed, "Lieutenant Anne O'Neemas was found dead half an hour ago. She was found holding her dagger and her wrists were slit. Looks like she killed herself."
One of the mercenaries sobbed as he said, "Impossible! Why would Anne kill herself! This must be a set-up!" David told the group, "I will try my best to hunt the killer, if there is one."
Joseph took a small bow at David. "Thank you, David."
