“ What exactly is it you'd like to know? [the book store manager asked]. He had an odd expression, like he was asking her a trick question. [Katherine] thought a minute. What DID she want to know? Why had she taken the trouble to come out in the cold to learn about a woman she'd never heard of until yesterday? She had that feeling she got when she was doing her art and suddenly discovered the missing piece that ties everything together: a tingling in the back of her neck, a crazy buzzed-rush of a feeling that spread through her whole body. She didn't understand the role that Sara Harrison Shea, the ring Gary had given her, or the book he had hidden would play, but she knew that this was important, and that she had to give herself over to it and see where it might lead. ”
