From Protector of the Grey House:
“Let her walk on her own.” Vincent’s voice was unreadable.
Mierka looked to Joseph. A look passed between them, and Joseph nodded minutely. Mierka released Natalia then quickly walked to Vincent’s side. Unseen, she withdrew something from a secret pocket, and waited for the inevitable.
As her body shook, Natalia started forward, and refused to look anywhere but the floor. She took one step then another, and allowed herself to relax as she drew closer to Joseph. She couldn’t get through him; she was safe. She was a step away from him when she felt the presence in her mind again. It urged her to place the small insignificant metal band on her pinky. As the ring called again, she shook then lunged toward Joseph.
