A/N: I'm not going to go into too much detail within the story, so I'll just let you know some of the basics. Harry, Ron and Hermione run an independent Auror organization called Trio. They solve cases that are handed over to them by the ministry as well as some private cases.

Harry Potter walked through the threshold of the small London flat. No matter how often he did it, his heart dropped every time he walked into a crime scene. He approached a young wizard standing over the body of a girl.

"Mr. Potter, sir," the wizard said, acknowledging him.

"Roarke," Harry greeted. "Report please."

"Yes sir. The victim has been identified as Stella Donahue. Age 19. Occupation, barmaid and waitress at the Leaky Cauldron. A co-worker noticed that she wasn't at work today. She came over to see if she was alright and found her like this. She sent a floo call to Magical Law enforcement from a neighbors flat.

Harry eyed the body while Roarke continued.

"So far there's no evidence to suggest any foul play. According to those who were first on scene, the wards were still up when they arrived."

"How did the coworker get in?" Harry asked.

"She said that she was allowed in through the wards."

Roarke looked at the girl and shook his head. "Sir, I must say that this is probably one of the most bizarre crime scenes I've ever encountered."

"Why is that?"

"There's nothing here. There's only one cup of coffee on the table. She's in her work robes. The victim looks completely healthy and there's no sign that anyone else had entered this apartment. It's almost as if there has been no crime committed. How does a healthy 19 year old girl drop dead?"

Harry looked at his colleague. "That's why the ministry called us, isn't it."

Not for the first time in his life, Ron Weasley was completely dumbfounded.

"This is unbelievable," Ron said looking over the piece of parchment in his hand. He had just received the preliminary report on their victims condition.

"What is it?" Hermione asked.

"Nothing. Absolutely nothing."

Hermione grew irritated and snatched the parchment out of his hand.

"Oh," she said after she read over the paper.

"See? Nothing. There's no poison in her system. All of her organs appear to be in perfect condition. She seems to have taken good care of herself. I haven't had a chance to look over the body myself, but I'm pretty sure I'll get the same results. Bloody hell. Three years of healer training, and I'm baffled."

"Are you going to check for spell damage?"

"I thought it was already decided that no one else had entered her flat?"

"Not exactly. We're wizards Ron. We can cover our tracks. Let's just get all of our bases covered."

"What?" Ron asked, confused.

Hermione sighed. "I mean, just check for any spell damage. I'm going to go find Colin to see if he's gotten those crime scene photos developed."

"I still don't understand why you lot were called. It doesn't look as though you're even dealing with a murder," Ginny Weasley said as she sat across from Harry at his desk.

"I know, but you you know how the ministry is. If things look suspicious, they call us."

"What have you got as far as evidence?" she asked.

"Not much, but even if we did I'm not totally sure I'd be able to share it with you," Harry replied.

"You're lucky that this isn't a high profile case. You'd have to come up with something better than that. You still don't even know how the girl died."

Ginny rose from her seat. "Good luck. I'm off to practice." She walked around to him and kissed him.

As Ginny walked out, Delia, the secretary walked in.

"Mr. Potter?"

"Yes Delia," Harry said.

"I've got the address for the victim's next of kin. I was supposed to give it to Mr. Weasley, but he's not here."

"That's fine Delia. I'll give him the message."

"Alright." She turned to leave, but hesitated.

"Is everything okay Delia?" Harry asked, noticing her hesitation.

"Er, yes. It's just...I was wondering..."

"What?"

"If you could get your girlfriend's autograph for me. Well, not for me. I'm not really into Quidditch. But my sister is 14 and she loves the Harpies, and Ginny is her favorite player."

Harry couldn't help but smile. If it weren't for the fact that he knew how brilliant Delia actually was, he'd assume that she was completely superficial. It was times like that Harry had to remind himself that Delia was an extraordinarily talented witch and an very intelligent woman.

"Sure Delia. I'll ask her."

"Thanks. Oh and I owled your preliminary reports to the minister and Magical Law Enforcement."

"Thank you Delia."

Harry was left to ponder the case on his own as she left.

"How in the hell did this girl die? How can we solve this case if we don't even know what happened?" Harry asked himself aloud.

Almost as if on cue, Ron rushed into Harry's office.

"I did some double checking on Donahue's body," said Ron.

"And?"

"She was murdered."

"How?"

"The killing curse."

"I don't know exactly what it is you're looking for Hermione, but I doubt you'll find it in these photographs," said Colin Creevey. Photos of witches and wizards moving about the victim's flat lay sprawled across Hermione's desk.

"I've looked over these pictures, and nothing really stands out."

"There's got to be something Colin. Something killed this girl and something in these photos will give me a clue."

Hermione inspected photo after photo and had almost given up, until Colin spotted something.

"Damn it! Why didn't I notice it? I was there," he shouted.

"What is it?" Hermione asked.

"Do you see that?" he asked, pointing to one of the agents in the picture.

"What is she doing?"

"I remember, it was bloody freezing in there, so Matthews closed the window," said Colin.

"Meaning the window was open when you all arrived?" Hermione asked, catching on.

"Yes."

"Excellent." she said before she rushed to Harry's office.

A/N: Sorry the chapter is short. The rest will probably be short as well. Anyway, like I said I'm not going to go into much detail about Trio in the story, so if you have any questions about anything, just ask. Also, I know the thing about Ron going through healer training seems a little far-fetched, it's for the sake of the story. It's that way because I want it to be. He's not really a fully qualified healer. He's sort of like a Medical Examiner.
