Chapter 1: Quirrell

"Please don't do this." The man begged.

"Oh, but I have to. How else will I get his attention?" the voice said. It was distinctly female. It was silky and filled with false sympathy, a voice that made the man stop and look for the owner.

"Don't worry, your sacrifice won't be in vain." The voice assured him. The next sound was of pain. The man had been set on fire. When he was ash the owner of the voice brandished her wand again. The ashes were clothed and she disappeared.

It had been a few weeks since the Saturday that Harry had revealed his big secret. The rest of the memory tapes were viewed and there were some questions but they were mostly those that you would get in any cross culture experience. The team had settled down and were treating him like they had before. Tony was still annoying, Tim still a geek, and Ziva still … Ziva. Harry was relaxing at his desk, paperwork finished, when Gibbs walked in.

"Gear up, we got a calling card for us."

When they arrived Harry felt the blood empty out of his face. The room had stairs leading down into an area. On the same level as the top stair were pillars surrounding the area. The corpse, if it could be called that, was dressed in a robe. There was a full length mirror that had a point at the top. The room looked like, for all intense and purposes, the room where Harry had fought Quirrell. The only thing marring the room was a message.

'Your personal Chamber of Secrets has been opened Special Agent Potter. Let's see if you can catch me before I get through with you.' The message said. It looked like it had been written in blood.

"Uh, boss, I know this scene." Harry said.

"Or rather most of it." He informed Gibbs.

"How?"

"You remember how I was out of it for three days my first year?" Gibbs nodded slowly, wondering where this was going.

"This is a replica of the room it happened in." Harry explained.

"So give us a play-by-play of what happened."Gibbs said.

"I walked in and saw Quirrell, who is being played by our vic" This was accompanied by a hand gesture to the pile of ashes.

"He stuck me in front of the mirror. At the time it was the Mirror of Erised. Tony, stand in the front of the mirror and tell me what you see." Harry yelled out.

"Sure." Tony stood in front and center of the mirror.

"I see me, the crime scene. What am I supposed to be seeing?" He asked.

"Nothing. Just checking a hunch." Harry replied, he turned to Gibbs again.

"Anyhow, in the mirror I see myself telling me where to find the sorcerer's stone. I then try to lie to Quirrell about what I see. He catches me and reveals that he is possessed by Riddle." Harry said.

"Wait, the same Riddle that caused the war?" Gibbs asked.

"The one and the same. Anyhow after an attempt to convert me he ordered Quirrell to kill me. However, because of my mother's protection charm Quirrell burned when he touched me. I touched his face, which shortened his misery. He collapsed as more of him turned to ash. When he was dead, Riddle rushed through me and I fell on the steps." Harry concluded.

"So the blood wasn't actually part of the room." Ziva concluded.

"No, it's a reference to the Chamber of Secrets, which only the heir of Salazar Slytherin could open. It contained a basilisk that would only obey the heir. A basilisk is a giant killer snake." Harry explained.

"So what? The perp is going to release your inner basilisk?" Tim asked.

"No, I think that they're going to reveal some of the things I don't want to reveal." Harry said. Ducky and Palmer arrived then.

"I don't think I'm going to be of much use here Jethro." Ducky said.

"I think you're right Duck." Gibbs responded.

"Well we should gather the remains anyway." With that Palmer jumped into action. He began scooping the ashes into a bag. With that the team, who had stopped to listen to Harry's story, began doing their job again.

"Blood is probably from roosters." Harry said.

"Well Abby will be able to tell." Tim said as he swabbed the message. The team did the rest of the gathering of evidence silently.
