Violet eased back behind an imitation palm tree, wedging open a slit in the branches with her fingers. Just the mention of a lie detector made her squirm, almost like she had worms crawling in and out of holes in her chest, but this extractor thing, ripping truth from bowels, that was another matter entirely. She had studied polygraphs, fretting for years over how to fool one in case she was ever confronted by one. According to Sloan, the assistant librarian at the city library, lie detectors were nothing but junk science. He had given her a book, The Polygraph: Lies You Tell, The Lies You're Told, and she had studied it, even practiced the countermeasures. Lie detectors were fallible. She was pretty sure she could beat one of those if it ever came to that.
