It was the third week of October and the school was already buzzing with talk of the up coming Halloween ball. Dawn felt herself wishing the students would concentrate more. This was unusual as these days she was very careful not to wish for anything whether thought or spoken. You never knew what could happen. She sighed as the children hurried off to their lunch. She hoped they would remember something of the last hour. She packed her journal and note book into her bag before heading off to the great hall herself.

Strolling down a long corridor she saw Professor Snape making his way towards her taking large amounts of points from random pupils as he made his way down the dark corridor and shot her a rather angry look as she passed him. She beamed at him despite his greeting. "Good morning Professor Snape." She chimed as he swept past in his billowing ropes.

So far he was the only member of the schools staff who hadn't greeted her with open arms; it had surprised and interested her. For years now she had been able to charm anyone she met, it just happened. At home though everyone seemed to have developed a resistance to whatever it was that made those around her so relaxed and helpful. Snape however seemed completely immune to her and she got the feeling he was interested in her too. It wasn't a pleasant feeling either.

In the doorway to the Charms classroom Professor Flitwick stood, she smiled at him and walked over. "Snape's not the friendly type, is he?"she stated while glancing in the direction said Potions Master had vanished. "Is he always like that?" Professor Flitwick nodded, "Afraid that's our professor Snape dear." "Has he ever cracked a smile?" Dawn laughed now. "Not that I can remember." The Charms Professor's jaw twitched before he felt himself laughing with the lady in white.

As he mad his hurried way back to his chambers after his class room Severus Snape felt his senses sharpen again, with each long stride his head seemed to get clearer until he was back to his usual cold and calculating self. Dawn could not have known how wrong she was in thinking she had no affect upon him, on the contrary it had taken all Severus' mental strength t old himself together whenever he was close to the mysterious Dawn Summers.

His pace sowed as he reached the dark wood door, he laid a hand on it before pausing briefly. He had been observing Summers since her arrival, hence his unusual presence in the great hall for supper these last few weeks, but she was still a complete mystery. Despite her friendly chat she never gave anything personal away or anything about her life before her appearance at Hogwarts.

Pushing the door open he entered and placed the books he had brought from the class room down and sat before the fire. He meant to continue observing the schools newest member of staff, she was hiding something. Her identity was indeed mystery and to Severus Snape a mystery had to be solved.

Gryffindor had a Defence Against the Dark Arts class after lunch with Hufflepuff. Harry and Hermione watched their professor as she smiled to herself while reading over the essays from the small pile of scrolls on her desk.

She was dressed differently again, she was wearing the trouser suit she had first arrived in but now she wore a cape over it. It had a high, stand collar that was rather pointed and fastened with a crescent shaped silver clasp.

The jacket part of her outfit hung open. Under it she was wearing a very lacy bustier, in white of course. Apparently white was the only colour she ever wore.

Her eyes were down as she read the texts before her. Harry managed to have a long look before she finally looked up. As she did he instantly returned his eyes to his own work. For some reason he couldn't meet her eye.
