From The Grey House, Book One:
There were a few times that her cell alarm went off when he was in the room with her. Each time, he asked her what it was. Each time, he seemed utterly and completely surprised when she pulled out her cell. The man seemed to overlook technology that couldn’t be used as weapons. When she first realized how little regard he had for technology, Natalia found it really strange. Now, locked in a spiked closet, she found it very useful. She could only hope for signal in this strange little closest. She reached into her jacket pocket and pulled out the cell and flipped it open. The phone showed full battery life and more important, full signal bars.
