Prentiss on protection detail

Prentiss got out of her car and looked around her at students milling about. She was standing on the campus of an exclusive finishing school, looking for her assignment. After a few moments she spotted a pretty dark-haired girl walking with a group of friends, all of them dressed like the others in light blue blouses, dark blue plaid skirts and straw boaters.

"Excuse me..." Prentiss made her way through the schoolgirls until she reached the girl she was aiming for, "Helen Martinelli?"

"Yes?" the girl looked up at Prentiss.

"My name's Emily Prentiss, I'm with the FBI. We have reason to believe you're at risk."

"What kind of risk?"

"Well, that's difficult to explain..."

"Why me, then?"

"Your father is the district attorney, and you turned eighteen a couple of months ago."

"What does that mean?"

"There's a criminal on the loose, he's targeting pretty girls who are linked to law enforcement in some way..." Prentiss glanced about at Helen's friends, who were looking her over judgmentally.

"Oh, that guy who leaves girls naked on the street?" Helen smiled, then her smile faded. "You think he'd do that to me?"

"It's a possibility, you're one of the people we think might be particular targets. I'm here to prevent that happening."

"Oh my god, look!" a girl said from behind her, causing Prentiss to squirm round.

"What?" Prentiss asked, seeing the girls taking out phones to photograph her.

"She can't even protect her own ass!" the girl laughed.

"Oh wow, look at the size of that!" another added.

Prentiss grabbed at the seat of her yoga pants and found it missing, clutching only her bare buttocks, her brightly-coloured thong not providing any cover. She tried to remember when that might have happened. Her cheeks began to burn as more schoolgirls gathered around, pointing and laughing at her bare behind.

"Please, Helen," Prentiss tried to ignore the humiliating situation, "We need to get you to..." Prentiss blinked and looked around.

Helen was gone.
