From The Grey House:
Rebecca was drinking a bad cup of coffee, wishing the safe house were across the street from a good coffee shop. She had been in worse surveillance situations though and shut her mind to the chatter. She watched Natalia out of the corner of her eye, wondering how she was going to get the homing device on the woman. It was a small device, designed to look like a quarter. It was marred on one side, as if someone had scratched up the backside. Rebecca was now twirling it slowly between her fingers, considering her options.
