From Protector of the Grey House:
“How did you escape?” Mierka’s voice was almost too quiet to hear.
Natalia turned her head to look at the lady. She sighed heavily and continued. “The one who believed me gave me back my cell phone in secret. When I was sure they had all left the house, I used my cell phone to call the police.” She paused, an odd look in her eye. The youngest Slayer, Ashley, gave her back her cell and confirmed she believed Natalia. She shook her head and continued her story.
