Chapter 1

Vivian Potter was not a morning person. Due to this, and her late return from London last night, she was not a happy camper this morning. Only on her second cup of coffee, it took her a few moments to remember that there was a book signing at her store today. David Rossi, retired Special Agent, Profiler, and ex Marine was signing his new book: Frenzy: America's Worst Spree Killers tonight at 5pm. This would make it a long day for Vivian.

After the war, the Wizarding World was exposed to the Muggles. There had been varied reactions to this revalation. Due to her part in the war, she was forced into the limelight, and became somewhat of an Ambassador to the Magical World. For someone who hated attention, this was a nightmare. After a couple of years, she had decided she needed a change of pace.

Vivian had always been rather quiet, and preferred peaceful pastimes over loud, boisterous ones. She decided to use some of her inheritance to open a Bookstore. Eighteen years later, and she had a chain of bookstores across the UK, and US - thirty two and counting. She was very proud of Spellbound Books. They sold both Magical, and Muggle titles.

She had settled down, married, and started a family. After her second child was born, her marriage started to slowly deteriorate. The stresses of their jobs, and the fact that they rarely saw each other, caused a rift between her and Kingsley. They finally decided to seperate before they started hating each other. They had a much better relationship now, than the last few years of their marriage.

She had returned home from London just last night, after dropping her children off with their Father. They had shared custody, and as both went back to Hogwarts in two weeks, she wouldn't see them in person until Christmas. Unless she went to watch a Quidditch game. She usually came for the Ravenclaw/Gryffindor game, since she had a son on each team.

Vivian hopped in the shower, and washed her long, wavy, dark brown hair. After that, she fixed her hair and make up. Less than half an hour later, she was on her way to her Downtown, DC location.

Dave Rossi had just come back to Virginia, by way of Spain. He was finishing up his latest book tour in his own backyard. He had decided to return to the BAU. Some of his unsolved cases had made him want another crack at them. He had unfinished business. He had a month off before he went back, and he needed it to decompress. Traveling so much for work was difficult, and he just needed to relax.

Several hours later, Rossi walked into Spellbound Books with his agent Christopher. He had never been in here, and he was very impressed with the warm, comfortable atmosphere. It was a large store, but still felt cozy- like you were at home, curled up reading on a rainy day. He could hear Frank Sinatra playing lowly throughout the store, and the smell of coffee permeated the air. The place was decorated in warm colors, and there were many inviting seating areas scattered throughout the space.

While he was looking around, Christopher was talking to a sales girl, asking her were to set up. "We have the perfect area set up for you, Mr Rossi. Ms. Potter, the owner, already has everything ready. Just let me call her, and let her know you are here." The bubbly girl said, picking up the phone at the service desk. "Ms. Potter? Mr. Rossi has arrived. Yes Ma'am." She said, then hung up. "Ms. Potter will be right down. Can I get you gentlemen a drink? Our coffee and tea selection is to die for!" She asked, bouncing up and down on the balls of her feet.

'Have I ever been that energetic?' Rossi thought, bemused. "That sounds wonderful. I'll have a double expresso, please. Two sugars." Rossi said. Christopher added his order, and she flounced off to get it. He heard the clatter of heels on metal, and turned his attention to the iron, spiral staircase on the left side of the store. The upstairs appeared to be offices, and a woman was descending from that direction.

At first, all he could see was her back, but as she came around the curve, he sucked in a quick breath. The woman was lovely- no, that didn't do her justice. She was gorgeous. She was a petite little thing, but other than her short stature, she was definitely all woman. She had long, wavy, dark brown hair cascading to well below her shoulders, full lips, sharp cheekbones, and creamy pale skin. She was wearing a black, kilt-like skirt that came to mid thigh, and black stockings. Her three inch heels added definition to her shapely legs, and she was wearing a kelly green, silk shirt that set off her best feature -her sparkling green eyes.

Vivian smiled warmly at Rossi and Christopher. "Welcome to Spellbound Books! My name is Vivian Potter, Founder and owner." She said, holding out her hand towards Rossi.

Dave took her hand, and instead of shaking it, kissed the back of it while giving her a subtle once-over. "Thank you. I am David Rossi, and this is my agent Cristopher Newgate. It is a genuine pleasure to meet such a bella signora." He said, causing her to blush lightly.

"What a charmer! No wonder there is a line of females out the door." She said, giving him a sexy grin. "Let's get you boys settled. Did Stephanie offer you something to drink?" Vivian asked, turning around and leading them to a table with a large display of his book around it. Both men took the opportunity to stare at her round, firm bottom. "I hope this is satisfactory?" She asked. There was a glass full of sharpies, spare paper, and promotional pictures on the table, with a banner behind it.

"It's perfect, thank you." Rossi said, accepting his expresso from the perky girl from earlier. "Thank you." He said to the girl, before looking back at Vivian.

"Here you go, boss. Half hot chocolate, half pumpkin latte." She said, handing a large cup of the strange concoction to Vivian.

"You are a Saint! Remind me to nominate you for canonisation later." Vivian said wryly, giving Rossi a wink before taking a drink.

'Is she flirting with me? Surely not.' Dave thought, hoping that she was. A few minutes, and more small talk later, and the book signing started. She kept his drink fresh, and brought him a glass of ice water, asking each time by whispering in his ear so as not to disturb his fans. It was driving him slightly mad, his ears were very sensetive! Worse than that, she would place her hand on his shoulder, lean down until she was a scant inch from his back, and whisper. Her breath against his neck was turning him on, bigtime!

The question was, was she doing it on purpose? Or was it all a misunderstanding?

The signing ended at 7:30. By the time everyone had left the line, it was 8pm, and the store was closing. As he gathered his things, he watched her talk to the store Manager, then her heard her stomach growl. "Did you eat lunch, boss?" He asked, giving her a stern look.

She looked at him sheepishly, shaking her head. "I got sidetracked by that call from Scotland, then started setting up. I'll get something on the way home, don't worry Mitchell." She said.

'Well, this is as good of an opportunity as any.' Rossi thought, slightly nervous. "Why don't you let me out for Supper? I'd like to thank you for all your help today." Dave said smoothly, voice luckily not betraying his nerves.

'Wait a minute, is he asking me out on a date?' Vivian wondered. Only one way to find out, she thought, summoning her Gryffindor Courage.

"That sounds wonderful, Mr. Rossi." She said with a shy smile.

"Please, call me Dave, or David." Rossi said, not quite believing his luck.

"Only if you call me Vivian." She said, then they left the store together.
