Equipment began to show up via FedEx, disguised as prototypes of consumer electronics devices that her pretend clients wanted to have mass-produced in China. The disguise was pretty easy to maintain; all electronic devices looked the same under the hood, being just circuit boards with chips on them. It was known that Chinese intelligence had begun to embed custom chips in circuit boards that were being shipped to the West, chips that were programmed to phone home and send back intelligence, and Olivia suspected that her original destiny—the one she’d been groomed for—had been to investigate that problem. So there was some symmetry, and a bit of satisfaction, in turning the tables. Following elaborate instruction sheets, sent to her, encrypted, by boffins in London and Fort Meade, she got these devices running in the office, listening in on any electromagnetic signals emanating from the apartment building. Data streamed in and got compressed and encrypted and squirted back to London and Fort Meade, where people who actually understood this stuff could pick it apart and make sense of it.
