Disclaimer: Yup, don't own anything. Wish I did, but I don't. This was just a fun idea I came up with the other day in a dream so I had to write it down. Sorry the Prologue is kinda slow.



It was set to be yet another exciting year at Hogwarts. The sorting hat had just finished placing the first year's into their new houses and the feast had begun. Harry, Ron, and Hermione sat at their usual places at the end of the Gryffindor table; now that they were entering their sixth year at the school the ceremony had become almost so routine that they could predict to the number of seconds that would pass between the student sitting down and the house being named. Little did they know however that a mysterious string of events were about to be unraveled.

Almost half way through the feast, Dumbledore stood and asked for everyone's attention. "Students, I have a special treat for you. Your newest Charms teacher has just arrived. Will everyone please welcome Ms. Serena Martin." The two large doors leading to the Great Hall were opened and a petite, brunette stepped through. A dark black cloak was wrapped firmly about her and Filch stepped to her to take it.

"Thank you so much Mr. Filch. And hello to you as well Mrs. Norris." She smiled giving the cat a quick pat. It was amazing what that cloak had kept concealed, and almost every male at Hogwarts could not help but stare. On several occasions a substitute professor had not been much older than the students, but Ms. Martin was a totally different story. Her beauty seemed timeless and she possessed an eerie sort of aura that hinted of her true powers. As she walked between the tables towards the head table where the professors dined, every head turned to follow her. Her dress was a fiery red with black trim and very flattering on her curvy figure, even her black robe could not hide her alluring shape.

She walked behind the seated professors and sat at the closest available seat, which was located next to Snape. He quickly rose and pulled her chair out for her.

"Thank you Professor Snape." For almost a moment it appeared as if Snape actually looked hurt by the pleasantry.

"You're welcome Professor Martin."

The feast continued and at its end the students were released to their separate dorms. Harry, Ron, and Hermione lagged behind to have a more intimate conversation about their newest teacher.

"Wasn't it weird! That was completely an odd moment up there!" Ron exclaimed.

"I know! It was almost as if Snape was going to be polite." Harry and Ron shared a good laugh over the thought of their dreaded Potions professor being polite.

"Well do you want to know what I thought was weird?" At their silence, Hermione continued. "The way that she came in and acted like she knew who Filch and Mrs. Norris were."

Ron looked at her completely puzzled. "That was what you thought was weird? Hello! Did you not notice the Snape thing at all?"

"Ron's right. We don't know anything about her. For all we know she could have been a student here a few years before us and that's why she knows who they are."

Hermione's eyes lit up with excitement. "For once Harry you had a great idea before me!"

"I did?" Harry asked looking to Ron for support on what exactly this great idea was.

"Yes! Now come on we've got to go to the library!"

Ron and Harry exchanged glances knowing that nothing they could do could possible deter Hermione from her job at hand.
