This isn't my first fanfic really, I've actually done ALOT . . . I just didn't wanna post them up xD. Anyhow, this is however my first fanfic to be posted on ! I've been hooked on the 39 clues for a couple years (since it came out) and I just love the romance, action, adventure, mystery and comedy! Same goes for Unnatural History! And since both stories are of the same genre's, I felt they were a perfect match up, I couldn't resist! It's gunna get tricky the closer to the end I get, BUT THIS IS JUST TO DARN FUN ! ! ! xD

(Disclaimer! I don't own anything or anyone!)

CHAPTER 1

Look Out D.C.

Running as fast as they could, eleven year old Dan and his fourteen year old sister Amy Cahill make it safely back to their hotel as to where they have been staying. They just out ran the clutches of Ian and Natalie Kabra and once again, the teams had wound up in Paris, France.

Walking into their room and still trying to catch their breaths, they meet the gaze of their au pair, Nellie Gomez and their cat Saladin.

"You guys made it!" Nellie cheered, "I was able to see you two run all this way from down the street out the window!"

"There has GOT to be an easier way to escape those Cobras!" Dan said as he plopped himself onto the arm chair.

"Dan, do you still have box?" Amy asked her brother, "Now might be a good time to look through it." Dan bent forward in his seat grabbing his back pack that he had tossed into the seat next to him and pulled out the box. Nellie's eyes grew wide as she set her gaze upon a rusted old metal jewelry box with a gold round plate on the lid, also with the Madrigal 'M' crested onto it. "Ok," Amy started as she walked over to him in the chair, "Now let me-" but before she could finish asking for it, Dan had already taken the lid off. "D-Dan!" Amy shouted in fear that he could possibly mess things up.

"Chill Amy," Dan told her handing her the lid, "There's nothing but papers in here anyway." Amy examined it quickly, then placed it on the coffee table in front of them. Dan started rummaging through all the papers.

"Amy!" Dan called to his sister as he held up what seems to be an old photograph, "I found another picture . . . of Grace." They were curious now, why would the Madrigals have a picture of Grace in safe keeping? "Who's that with her?" Dan asked. "Never seen him before." Amy snatched the photo from him and looked. On the picture was Grace standing next to a man. It didn't look to old, almost 10 years. They were in a building and behind them was a smaller replica of an Easter Island head. It took a few minutes before Amy gasped at her realization.

"I know who this is!" She said excitedly, "I've seen him before, when my class took that field trip the museum of fine arts."

"So he's an artist?" Dan questioned.

"Try researcher. I remember being told that he works for the Smithsonian Museum."

"Isn't the Smithsonian the worlds biggest museum?" Nellie asked leaning on the back of the arm chair.

"And in Washington D.C." Amy smiled. Dan grabbed the picture back from her and looked over it once again.

Dan scrunched his eyebrows, "Do you remember what his name was? I want to see if there's any dirt on this guy. Maybe something that can tell us what he was doing with Grace." Amy thought for a moment, racking her mind for the man's name. But nothing came to her.

"For once, I don't know." Amy sighed in defeat. Dan and Nellie gasped.

"Yeah, now it's my turn!" Dan cheered. He handed the box of papers along with the photo to Amy. He grabbed his back pack again and got out his laptop. He logged on and began to do some research. After a few minutes of waiting, Dan finally found what they were looking for. "Found our man." He said. On the screen were some picture of the same man. Older, facial and white hair in a long ponytail behind him and dressed like he'd just arrived from Australia. Dan couldn't find anything that connected him and Grace, but by the looks of that picture says there is.

Nellie looked over his shoulder again, "It says his name is Dante Morneau. Yup, researcher at the Smithsonian Museum in D.C."

Amy took another good look at the photo of Grace and Dante.

"Hey, what's that written there?" Dan pointed to the back of the photo.

Amy flipped it around, "Happy Easter." She said reading the back aloud. Easter was all capitalized. "I get the feeling this is our next destination."

"What? The Easter Island heads that are out on the Pacific?" Dan questioned.

Amy rolled her eyes and looked to Dan, and he could tell what she was think, 'No you dweeb, the museum.' Dan slumped back in his chair with a pout, he didn't want to go to another museum, even if it was the biggest in the world.

All three of them had boarded the plane and made it out of Paris early morning. They would soon be landing at the Ronald Reagan Washington National Airport in D.C. Amy was sitting next to the window and looked outside. It then dawned on her that they could have been fallowed. She paled and gulped at the thought. 'Anyone could be fallowing behind us right now.' She thought worriedly, 'What if it's the Kabra's again!' Her eyes widened.

"Amy? You ok kiddo?" Nellie asked noticing her awkward quietness. Amy popped back into reality and twisted in her seat. Dan was there next to her, he looked at his sister questioningly; Then there was Nellie.

"I'm alright. Don't worry." Amy told them trying to put on a small fake smile. Dan and Nellie studied her for a few seconds before doing what they were doing before. Nellie was bobbing her head up and down as she was listening to her ipod which was most of the time on full blast and Dan was snacking on airplane snacks. Amy sighed, calming herself down and looked out her window once again. The straight streets and angles of D.C. finally came into view. The announcement over the intercom announced that they would soon be landing.
