Karyn figured that the best approach was the direct approach. She decided to go straight to Sarah's house, sneak in, and steal back the stone.
"Wait here, Jon. I'll be right back," she said.
"Be careful, Karyn."
Karyn ran down the street until she was standing just outside Sarah's house. There were no lights on at all at the front, so cautiously, she snuck around the side of the house to the back.
At the back, a single upstairs light was showing through drawn curtains. Karyn figured it was a good bet that it was Sarah's room. Fortunately for her, there were climbing roses entwined around a wooden frame, just next to the window with the light. Ever so carefully, Karyn climbed up the frame until she was level with the window. She picked up a few painful cuts on the way from the thorns, but soon had herself in a position where she could lean over and peek through a gap at the edge of the curtains and into the room.
Karyn hestitated a few seconds before leaning across. She reassured herself that this was Sarah's house and room and that she wouldn't find herself quickly arrested for peeking at some old lady in her underwear.
With a deep breath, Karyn leaned across and looked in the gap. She was relieved to see that it was indeed Sarah's bedroom. She was looking at herself in a mirror, wearing just her panties and bra. And in her hand was the stone!
"Bitch," Karyn whispered. Unfortunately, Karyn's voice was loud enough for Sarah to hear her. Sarah walked over to her window and pulled back the curtain.
Karyn's eyes went wide and lost her grip and began to fall backwards, but then her location changed. She was in Sarah's room. Apparently, Sarah wished her there.
"Spying on me, huh? What kind of weirdo are you?" Sarah said.
