Thanks to Tumblr user mushi0131 who wanted a story written with this prompt, and who am I to argue? I'm a sucker for nalu and writing stories when I have 10 others that aren't completed.

He'd been staring furiously at the papers all day, trying to commit all the information they contained to memory. It was like throwing a bunch of darts at a board and hoping they all stuck. Natsu had never been good at darts but he was a good detective and this was possibly the biggest bust of his career. He'd do whatever it took to take them down, even if it meant memorizing every detail about the fake company, Lucky Lucy, and the companies CEO and daughter.

Natsu leaned back in his too small chair and stretched, feeling every joint in his body crack. Sitting at a desk all day was not what he signed up for when becoming a detective, but as with most things in his life, not a lot went according to plan. Besides, soon enough he'd be out in the field.

"Too much for you, Natsu?" Gray asked, raising his eyebrows, smirking. "If you can't handle it I can gladly take over. You've never been much with the ladies after all."

Gray, Natsu's deskmate, and longtime partner, had to be the cockiest and most insufferable person he'd ever met. Coincidentally, Gray felt the same way about Natsu.

"Shut your trap," Natsu growled, cracking his neck. "You couldn't handle this if Heartfilia gave you his transaction logs himself."

Jude Heartfilia, owner of the company Lucky Lucy, a business that made and sold locks and keys, was a front for arms trafficking to distant countries, or at least that's what the police suspected. They'd been investigated for years with no full proof evidence, driving the police up the walls. But there was finally a break in the case when it was revealed that Jude had a daughter, something he'd clearly been trying to keep a tight lid on. Word spread fast when it came out that a girl with the same likeness and last name as him had published a book and worked at a huge newspaper in town.

Gray ignored the invitation for a fight if only because Makarov, their captain was watching with narrowed eyes. One raised fist and they'd both be forced to desk duty for the rest of their lives.

"You know," Gray drawled, leaning closer to Natsu over their desks, "I hear the daughter is quite a catch. Make sure not to fall in love, yeah?"

Natsu snorted. He glanced back down at the file on his desk containing all the information about dear old Lucky Lucy Heartfilia. Twenty-three, a year behind him, she grew up isolated from the world and kept completely secret. Not much is known about her before she got a job at a newspaper company and published a book that sold over a million copies just a few months ago.

Natsu's task was simple. Go undercover, gain her trust and then, of course, take down one of the most renowned arms trafficking businesses.

He wasn't sure how much she knew about her father's business, but since she still lived with him, it at least gave him an in. He'd do whatever it took to take them down.

"Fat chance," Natsu drawled back. "I'm more concerned about her falling in love with me," he snickered. His amusement was short-lived when he felt a sharp slap hit him in the back of the head.

"Don't you dare play with a woman's heart, Natsu," a sharp voice commanded. Natsu flinched and turned. Erza, their sergeant stood over him, glaring daggers. He nodded quickly, not bothering to explain that he was joking; it likely wouldn't help. Erza wasn't one for humor when it came to love. Seeming satisfied, she said, "Are you ready, Natsu? You should head out soon."

Natsu glanced down at his watch. Nearly noon.

Nodding, he stood and grabbed his jacket, leaving his gun and badge on the desk. Instead of the tie and semi-professional clothes he usually wore, he'd donned a casual T-shirt and jeans with sneakers, perfect for the occasion. His died pink hair was left loose instead of slicked back like usual.

Levy, their resident nerd and computer programmer, called a quick good luck as he stalked out of the bustling station. He grinned, feeling the adrenalin rush through his system. Here were his first few steps to the biggest bust in his career.

It was a couple block walk, enough to make him start to sweat under the beating sun. Natsu was secretly grateful for it. The more he looked like a guy coming straight off the street, the better.

Finally, he arrived at his destination. A little café snugged between a bookstore and a small grocery store. Every Wednesday Lucy Heartfilia showed up at noon, sat in a corner and wrote.

It only took him a second to locate her head, bent over the table, writing furiously in a notebook. He ordered a cup of coffee and walked towards her. He stopped in front of her and smiled in amusement when she didn't even notice him. He cleared his throat, causing her head to snap up in surprise.

"Mind if I sit here?"
