Disclaimer: I don't own the 39 Clues. I don't own any of the 39 Clues characters. I do, however, own the character Eímai Katáskopos. And I can send him after you anytime I want… *bwahahahaha*

Eímai got out of the limo and onto the busy Swedish street. A few people stared as he went into the lobby of Dan and Amy's hotel. Who wouldn't? To other people he looked like a walking trench coat in sunglasses and a hat.

Once in the lobby, he paid two shifty-looking men five hundred kronor (about 70 US dollars) to get into a fight. This they did happily, causing the manager at the check-in desk to scurry over and try to break up the fight. Eímai slipped behind the desk and used the computer to find the Cahill's room number. 432. He then shuffled into the elevator and pressed the button for the fourth floor, glad there wasn't a security camera (he had to jump to reach the button).

The elevator stopped to let on a chattering Swedish family. They hardly noticed the midget in a trench coat watching their every move.

Dan dozed as his history-addicted sister read an unbelievably boring book on Swedish history. "Dan, listen to this! Isn't it interesting?"

He lazily opened one eye. "No."

Amy rolled her eyes. "Whatever. Here, I bet you'll like this book. Read it until Nellie gets back with dinner."

She tossed him a guidebook that she'd bought at the castle's gift shop. Dan started to toss it back when he saw the cover. It had a picture of a Viking longship on the front. He didn't want to admit it, but he was vaguely interested. Flipping to a random page, he saw what he wanted. "Hey, this actually pretty cool. Look at this sword!"

"Told you you'd like it." Amy picked up Saladin, who was dozing on one of the beds. He looked up at her lazily with golden eyes.

"Don't worry, kitty. Nellie's going to be back soon with all sorts of food. I bet you'll love it. Knowing Nellie, she'll get something traditional. Around here, that means fish." Amy petted the cat.

Saladin lazily groomed himself while staring at Amy in that way that cats do. You know, like they know something you don't. The reason that cats do this is because they usually do know something you don't. They just don't care. They have all their mysterious kitty secrets that could they could destroy the world with if they wanted to.

"Where's Nellie? She should have been back by now." Amy went to the window and looked out.

"No idea. Hey! I could be a Viking berserker! Awesome!" Dan swung a pretend sword around and made battle noises.

Not again, thought Amy. At least we're not in public this time.

There was a knock on the door. "It's probably Nellie. She left her keycard here by accident." Dan sat down on the bed with the Viking book. "You get it. I'm busy."

Amy rolled her eyes, but went to the door anyways. She opened the door a crack. Sure enough, there was Nellie, her arms full of grocery bags. "You gonna let me in?" she said. "I got dinner."

Amy held the door wide and Nellie stepped in. As Nellie set the bags down on the table, Amy could have sworn she saw something dart into the hotel room from the hallway, but when she checked, there was nothing there. Probably just a shadow, she thought, mentally shrugging.

"Yay! Food! Watcha get?" Dan dropped the book.

"Whoa, am I going crazy or was Dan Cahill actually reading a book?" asked Nellie, pulling things from a grocery bag.

"Well, it's about Vikings, so I've got an excuse…" Dan grabbed a cylinder-shaped package. "Are these cookies?"

Nellie snatched it back. "Yes, they're cookies, and they're for after dinner."

"Awww…"

Amy helped Nellie put the food in the bedroom's minifridge while Dan examined it. "Seems almost exactly like American food," he said, unwrapping a deli sandwich.

"I could have gotten lutefisk, but I figured you'd kill me if I did." Nellie turned on the TV and munched on some potato chips. "Crud, it's all in Swedish. Oh well."

"What's lutefisk—no, nevermind, I don't want to know." Dan went back to his Viking book while eating a sandwich. "Ooh! A battle axe! Bet I could beat the Holt dolts with that!"

Amy settled down in a comfy chair with a guidebook and a sandwich. She opened the book and started reading about the thousand-year-old town Knivsta. She was soon so lost in the book that she wouldn't have noticed if the building exploded.

Nellie was absorbed in a Swedish cooking show, Dan was deciding that there might be something worth learning about besides ninjas, and Amy was as good as in Knivsta. Which is why no one noticed what would have appeared to be a trench coat wearing a hat hiding behind the curtain.

Eímai was in the targets' bedroom. And he was ready to take them out.
