Case File:

"I swear you get more annoying by the minute." Liam chided as he and Louis walk down the hallway.

"I'm not annoying. I'm simply persistent." Louis rebuttals. He hates when people call him annoying. He is not annoying, but rather insistent on getting answers. "If you would just tell me why you didn't answer my texts yesterday, I'd leave you alone."

"I've already told you, I fell asleep."

"Don't believe it."

"Well then that's your problem." Louis just scowls, reaching his locker and turning the dial. He pulls it open only to reveal a neatly folded envelope sitting on his textbooks. He gives it a curious glance before picking it up to examine it further. He unfolds it to find that it's some sort of letter.

Dear Louis,

So like I realize how cheesy this is, but I'm writing you a love letter. It's silly I know, but I didn't know how else to tell you. Louis you're incredible did you know that? You are like the most amazing human being I've ever met. Sometimes I get so lost in your eyes. When you're really happy they're a bright blue, When you're angry their a vibrant teal. There are days when all I can think about is the way you talk or laugh, wishing I could spend the rest of my life hearing you. You have such a crazy personality, yet you can be so serious when I need your help. I think it's crazy how hard I've fallen in such a short amount of time. I guess it was a long time coming Oh I also love how sweet and kind you always are. You make sure to help your sisters when they need it or your mum when she needs a babysitter. You are such a wonderful person and I don't know how it's possible I got so lucky in meeting you. xanonymousx

"What's that?" Liam asks, trying to peek over his shoulder to read it.

"I think it's a love letter." He hands it to Liam who skims through the words quickly.

"Oh my God, you have a secret admirer." Louis blinks. He can't believe it. He honestly never thought this would happen to him. No one has ever told him they've had feelings for him before, much less given him a love letter. "I have to know who wrote this."

"But they didn't leave a name." Louis gives him a blank look then smacks his arm.

"Obviously, it's called a secret admirer for a reason." Louis has to know, no, he needs to know who wrote this letter. The only thing he knows so far is that this person is pretty close to him. "We have to figure out who it is." Liam scratches his head, thinking of a way to help his friend.

"I've got it!"

"What? What!?" Louis asks, shaking his shoulders to get the words out of him.

"We could be like those FBI agents on TV." Louis drops his hands and stares at Liam incredulously.

"What?"

"Just call me Detective Payne."
